SAFETY INSTRUCTIONS

WARNING

Radio Frequency Radiation Hazard

The radar antenna emits electromagnetic radio frequency (RF) energy which can be

harmful, particularly to your eyes. Never look directly into the antenna aperture from a

close distance while the radar is in operation or expose yourself to the transmitting

antenna at a close distance.

Distances at which RF radiation levels of 100 and 10 W/m²exist are given in the table

below.

Note: If the antenna unit is installed at a close distance in front of the wheel house,

your administration may require halt of transmission within a certain sector of antenna

revolution. This is possible. Ask your FURUNO representative or dealer to provide

this feature.

SAFETY INSTRUCTIONS

WARNING

Use the proper fuse.

WARNING

ELECTRICAL SHOCK HAZARD

Do not open the equipment.

Use of a wrong fuse can result in damage

to the equipment or cause fire.

Only qualified personnel

should work inside the

equipment.

Keep heater away from equipment.

Turn off the radar power

switch before servicing the

antenna unit. Post a warn-

ing sign near the switch

indicating it should not be

turned on while the antenna

unit is being serviced.

Heat can alter equipment shape and melt

the power cord, which can cause fire or

electrical shock.

Do not place liquid-filled containers

near the equipment.

Fire or electrical shock can result if a liquid

spills into the equipment.

Prevent the potential risk of

being struck by the rotating

antenna and exposure to

RF radiation hazard.

Do not operate the equipment with wet

hands.

Wear a safety belt and hard

hat when working on the

antenna unit.

Electrical shock can result.

Before servicing the radar, turn off

the appropriate external breaker.

Serious injury or death can

result if someone falls from

the radar antenna mast.

Power is not removed from the radar simply

by turning off its power switch.

Do not disassemble or modify the

equipment.

Fire, electrical shock or serious injury can

result.

Immediately turn off the power at the

ship's mains switchboard if water

leaks into the equipment or the equip-

ment is emitting smoke or fire.

Continued use can cause fatal damage to

the equipment.

SAFETY INSTRUCTIONS

CAUTION

The plotting accuracy and response of

this ARP meets IMO standards.

Tracking accuracy is affected by the

following:

WARNING

No one navigational aid should be relied

upon for the safety of vessel and crew.

The navigator has the responsibility to

check all aids available to confirm

position. Electronic aids are not

• Tracking accuracy is affected by course

change. One to two minutes is required to

restore vectors to full accuracy after an

abrupt course change. (The actual

amount depends on gyrocompass

specifications.)

• The amount of tracking delay is inversely

proportional to the relative speed of the

target. Delay is on the order of 15—30

seconds for high relative speed; 30—60

seconds for low relative speed.

a substitute for basic navigational

principles and common sense.

• This ARP automatically tracks

automatically or manually acquired radar

targets and calculates their courses and

speeds, indicating them by vectors. Since

the data generated by the auto plotter

are based on what radar targets are

selected, the radar must always be

optimally tuned for use with the auto

plotter, to ensure required targets will not

be lost or unwanted targets such as sea

returns and noise will not be acquired

and tracked.

The data generated by ARP, AIS and

video plotter are intended for

reference only.

Refer to official nautical charts for

detailed and up-to-date information.

• A target does not always mean a land-

mass, reef, ships or other surface vessels

but can imply returns from sea surface

and clutter. As the level of clutter changes

with environment, the operator should

properly adjust the A/C SEA, A/C RAIN

and GAIN controls to be sure target

echoes are not eliminated from the

radar screen.

WARNING LABEL

Warning labels are attached to the

equipment. Do not remove any label.

If a label is missing or damaged,

contact a FURUNO agent or dealer

about replacement.

Precautions for high speed targets

Assume your ship is making 40 kt and a target ship is approaching at 40 kt right toward you. Then

the relative speed is 80 kt. With the antenna rotating at 42 rpm, the target blip appears jumping to a

new location 59 m nearer. This jump corresponds to 19 mm on the display using the 0.25 nm range

scale. On such a short range you may lose the track of a target in the midst of sea clutter, random

noise or other targets. Use one step larger range scale.

ARPA can fail to track a target when the relative speed exceeds 100 kt.

1. RADAR OPERATION

1.1

Turning on the Power

The [POWER] switch ( ) is located at the left corner of the control unit. Open the

POWER switch cover and press the switch to turn on the radar system. To turn

off the radar, press the switch again. The screen shows the bearing scale and

digital timer approximately 30 seconds after power-on. The timer counts down

three minutes of warm-up time. During this period the magnetron (transmitter

tube) is warmed for transmission. When the timer has reached 0:00, the

indication “ST-BY” appears at the screen center, meaning the radar is now ready

to transmit pulses.

In the stand-by condition, markers, rings, map, charts, etc. are not shown.

Further, ARP is cancelled and the AIS display is erased.

In warm-up and stand-by condition, ON TIME and TX TIME counts in hours and

tenths of hour appear at the screen center.

Note: Avoid turning the power on directly after it has been turned off. Wait

several seconds before reapplying the power, to ensure proper start up.

1.2

Transmitter ON

After the power is turned on and the magnetron has warmed up, ST-BY appears

at the screen center, meaning the radar is ready to transmit radar pulses. You

may transmit by pressing the [STBY/TX] key on the full keyboard or roll the

trackball to choose the TX STBY box at the bottom left corner of the display and

then push the left button (above the trackball). The label at the left-hand side of

the guidance box at the bottom right corner of the screen changes from TX to

STBY.

1. RADAR OPERATION

The radar is initially set to previously used range and pulse length. Other

settings such as brilliance levels, VRMs, EBLs and menu option selections are

also set to previous settings.

The [STBY/TX] key (or TX STBY box) toggles the radar between STBY and

TRANSMIT status. The antenna stops in stand-by and rotates in transmit. The

magnetron ages with time resulting in a reduction of output power. Therefore, it

is highly recommended that the radar be set to stand-by when not used for an

extended period of time.

Quick start

Provided that the radar was once in use with the transmitter tube (magnetron)

still warm, you can turn the radar into TRANSMIT condition without three

minutes of warm-up. If the [POWER] switch has been turned off by mistake or

the like and you wish to restart the radar promptly, turn on the [POWER] switch

not later than 10 seconds after power-off.

Echo area

The echo display area for the non-IMO radar is available in three configurations:

round, wide, and full screen. You can select configuration with 7 ECHO AREA on

the ECHO menu.

Operation Using the On-Screen Boxes

All radar functions can be accessed by using the trackball alone. This is done by

choosing the appropriate on-screen box with the trackball and operating the

trackball module to choose item and option. (See paragraph 1.9 for location of all

on-screen boxes.) On-screen boxes come in two varieties: Function selection

and function selection w/pop-up menu. On-screen boxes of the latter type have

“►” at the right side of their boxes, as in the MARK box shown below.

To operate the radar using on-screen boxes, do the following:

1. Roll the trackball to place the trackball marker inside the box desired.

Note: The trackball marker changes its configuration according to its location.

It is an arrow when placed outside the effective display and a cursor

(+) when inside the effective display. See the illustration on the next

page for further details.

For example, choose the MARK box, which is at the bottom left corner.

1. RADAR OPERATION

1.12.2 Description of presentation modes

Head-up mode

The head-up mode is a display in which the line connecting own ship and the top

of the display indicates own ship’s heading.

The target pips are painted at their measured distances and in their directions

relative to own ship’s heading.

A short line on the bearing scale is the north marker indicating heading sensor

north. A failure of the heading sensor input will cause the north marker to

disappear and the readout to show ***.*° and the message HDG SIG MISSING

appears in red at the lower-right corner of the screen.

Heading Line

North Marker

Note: When display is off-centered,

the heading mark appears at 000 degrees.

Head-up mode

Course-up mode

The course-up mode is an azimuth stabilized display in which a line connecting

the center with the top of the display indicates own ship’s intended course

(namely, own ship’s previous heading just before this mode has been selected).

Target pips are painted at their measured distances and in their directions

relative to the intended course, which is maintained at the 0-degree position. The

heading line moves in accordance with ship’s yawing and course change. This

mode is useful to avoid smearing of picture during course change.

1. RADAR OPERATION

Head-up TB (True Bearing) mode

Radar echoes are shown in the same way as in the head-up mode. The

difference from normal head-up presentation lies in the orientation of the bearing

scale. The bearing scale is heading sensor stabilized. That is, it rotates in

accordance with the heading sensor signal, enabling you to know own ship’s

heading at a glance.

This mode is available when the radar is interfaced with a gyro heading sensor.

If the gyro heading sensor fails, the bearing scale returns to the state of head-up

mode.

North-up mode

The north-up mode paints target pips at their measured distances and in their

true (heading sensor) directions from own ship, north bearing maintained at the

top of the screen. The heading line changes its direction according to the ship’s

heading. Requires heading signal.

If the compass fails, the presentation mode changes to head-up and the north

marker disappears. Also, the HDG indication shows ***.*°. And the message

HDG SIG MISSING appears in red at the lower-right corner of the screen.

North Marker

Heading Line

North-up mode

Stern-up mode

The stern-up mode rotates the

dual-radar tugboats when backing up;

one radar shows head-up and another

shows stern-up. To enable the

stern-up mode, turn on STERN-UP on

the 7 OPERATION menu. Stern-up is

not available on the IMO or A type.

1. RADAR OPERATION

True motion mode

Own ship and other moving objects move in accordance with their true courses

and speed. In ground stabilized TM, all fixed targets, such as landmasses,

appear as stationary echoes. In the sea stabilized TM without set and drift inputs,

the landmass can move on the screen. Note that true motion is not available on

the 72 nm (non-IMO type only) or 96 nm range scale. If COG and SOG (both

over the ground) are not available on TM mode, enter the set (tide direction) and

drift (tide speed) manually referring to the Tide Table.

When own ship reaches a point corresponding to 50% of the radius of the

display, own ship position is automatically reset to a point of 75% radius opposite

to the extension of the heading line passing through the display center. You may

also reset the own ship symbol manually by pressing the [CU/TM RESET] key,

or roll the trackball to choose the CU/TM RESET box at the bottom right corner

of the display and then push the left button.

If the heading sensor fails, the mode is changed to the head-up and the north

marker disappears. The HDG readout shows ***.*° and the message HDG SIG

MISSING appears in red at the lower-right corner of the screen.

1. RADAR OPERATION

1.16 Adjusting the Sensitivity

The gain control adjusts the sensitivity of the receiver.

The proper setting is such that the background noise is just visible on the screen.

If you set up for too little sensitivity, weak echoes may be missed. On the other

hand excessive sensitivity yields too much background noise; strong targets may

be missed because of the poor contrast between desired echoes and the

background noise on the display.

To adjust receiver sensitivity, adjust the gain control so background noise is just

visible on the screen.

By keyboard

While monitoring the gain level indicator at the top of the screen, operate the

[GAIN] control to adjust the sensitivity.

1.17 Suppressing Sea Clutter

Echoes from waves cover the central part of the display with random signals

known as sea clutter. The higher the waves, and the higher the antenna above

the water, the further the clutter will extend. When sea clutter masks the picture,

suppress it by the A/C SEA control, either manually or automatically.

1. Roll the trackball to choose SEAAUTO or SEA MAN (whichever is shown) at

the top of the display.

2. Push the left button to display SEAAUTO or SEA MAN as appropriate.

1.17.2 Automatic adjustment by the A/C SEA control

Auto A/C SEA allows for fine tuning of the A/C SEA circuit, within ±20 dB.

Accordingly, with the bar reading set to 100, gain is not lowered to minimum as

with manual A/C SEA on close-in ranges. Further, the auto A/C SEA level is low

because the average value of the original input echo is low in areas where there

are no sea surface reflections. For example, when the ship is alongside a quay

and the radar picture shows echoes from both land and sea, you can observe

the size of echoes because the STC curve is different depending size of echoes.

Note: The auto A/C function can erase weak target echoes. Adjust the control

carefully, watching the display.

By keyboard

1. Choose SEAAUTO following the procedure in paragraph 1.17.1.

2. While observing the A/C SEA level indicator, adjust the A/C SEA with the [A/C

SEA] control. 100 levels are available.

increase the A/C SEA or upward to decrease it. 100 levels (0-100) are

available.

1.17.3 Manual adjustment of A/C SEA

The A/C SEA control reduces the amplification of echoes at short ranges (where

clutter is the greatest) and progressively increases amplification as the range

increases, so amplification will be normal at those ranges where there is no sea

clutter.

The proper setting of the A/C SEA should be such that the clutter is broken up

into small dots, and small targets become distinguishable. If the setting is set too

low, targets will be hidden in the clutter, while if the setting is too high, both sea

clutter and targets will disappear from the display. In most cases adjust the

control until clutter has disappeared to leeward, but a little is still visible

windward.

1.18.2 Adjusting A/C RAIN

The vertical beam width of the antenna is designed to see surface targets even

when the ship is rolling. However, by this design the unit will also detect rain

clutter (rain, snow, or hail) in the same manner as normal targets.

The A/C RAIN control adjusts the receiver sensitivity as the A/C SEA control

does but rather in a longer time period (longer range). The higher the setting the

greater the anti-clutter effect. When echoes from precipitation mask solid targets,

adjust the A/C RAIN control to split up these unwanted echoes into a speckled

pattern, making recognition of solid targets easier.

1.19 Interference Rejector

Mutual radar interference may occur in the vicinity of another shipborne radar

operating in the same frequency band. It is seen on the screen as a number of

bright spikes either in irregular patterns or in the form of usually curved

spoke-like dotted lines extending from the center to the edge of the picture.

Activating the interference rejector circuit can reduce this type of interference.

The interference rejector is a kind of signal correlation circuit. It compares the

received signals over successive transmissions and suppresses randomly

occurring signals. There are three levels of interference rejection depending on

the number of transmissions that are correlated.

1.20 Measuring the Range

The range to a target may be measured three ways: with the fixed range rings,

with the cursor, or with the VRM.

Use the fixed range rings to obtain a rough estimate of the range to a target.

They are the concentric solid circles about own ship, or the sweep origin. The

number of rings is automatically determined by the selected range scale and

their interval is displayed at the upper-left position of the screen. Count the

number of rings between the center of the display and the target. Check the

range ring interval and judge the distance of the echo from the inner edge of the

nearest ring.

1.20.1 Turning range rings on/off

1.22 Collision Assessment by Offset EBL

The origin of the EBL can be placed anywhere with the trackball to enable

measurement of range and bearing between any targets. This function is also

useful for assessment of the potential risk of collision. It is possible to read CPA

(Closest Point of Approach) by using a VRM as shown below (Figure (a)). If the

EBL passes through the sweep origin (own ship) as illustrated (Figure (b)), the

target ship is on a collision course.

1.22.1 How to assess risk of collision by the offset EBL

By keyboard

1. Press the [EBL ON] key to display or activate an EBL (No. 1 or No. 2).

2. Place the cursor (+) on a target appearing as threatening (A in the illustrated

example on the next page) by operating the trackball.

3. Press the [EBL OFFSET] key, and the origin of the active EBL shifts to the

cursor position. Press the [EBL OFFSET key] again to anchor the EBL origin.

4. After waiting for a few minutes (at least 3 minutes), operate the EBL rotary

control until the EBL bisects the target at the new position (A'). The EBL

readout shows the target ship's course, which may be true or relative

depending on the EBL bearing reference setting.

Note: If relative motion is selected, it is also possible to read CPA by using a

VRM as shown in left-hand figure at the top of the next page. If the

EBL passes through the sweep origin (own ship) as illustrated in the

right-hand figure at the top of then next page, the target ship is on a

collision course.

5. To return the EBL origin to the own ship's position, press the [EBL OFFSET]

key twice.

By trackball

1. Display an EBL, following steps 1-3 in “By trackball” in paragraph 1.21.1.

2. With the cursor inside the effective display area, push the left button, roll the

wheel to show “EBL OFFSET / EXIT” in the guidance box and then push the

left button.

3. Roll the trackball to place the offset EBL on a target appearing as threatening

(A in the illustrated example on the next page) and then push the left button

to anchor the EBL origin.

4. After waiting for a few minutes (at least 3 minutes), operate the EBL used in

step 1 until it bisects the target at the new position (A'). The EBL readout

shows the target ship's course, which may be true or relative depending on

the EBL bearing reference setting.

To return the EBL origin to the screen center, show “EBL OFFSET / EXIT” in the

guidance window and then push the left button.

1.25 Off-Centering the Display

Own ship position, or sweep origin, can be displaced to expand the view field

without switching to a larger range scale. The sweep origin can be off-centered

to the cursor position, but not more than 75% of the range in use; if the cursor is

set beyond 75% of the range scale, the sweep origin will be off-centered to the

point of 75% of the limit.

This feature is not available on the 72 nm (Non-IMO type only) or 96 nm range

scale nor in the true motion mode.

To off-center the radar picture, do the following:

By keyboard

1. Roll the trackball to place the cursor at a position where you wish to move the

sweep origin.

2. Press the [OFF CENTER] key. Then, the sweep origin is off-centered to the

cursor position.

3. To cancel off-centering, press the [OFF CENTER] key again.

By trackball

1. With the cursor inside the effective display area, roll the wheel to display

“OFF CENTER / EXIT” in the guidance box and then push the wheel or the

left button.

2. Roll the trackball to place the cursor where you want to locate the screen

center.

3. Push the left button to off center the sweep origin.

The echo stretch feature enlarges targets in the range and bearing directions to

make them easier to see, and it is available on any range. There are three types

of echo stretch, 1, 2 and 3, and the higher the number the greater the amount of

stretching.

Note: The echo stretch magnifies not only small target pips but also returns

(clutter) from sea surface, rain and radar interference. For this reason,

make sure these types of interference have been sufficiently suppressed

before activating the echo stretch.

1.27 Echo Averaging

The echo averaging feature effectively suppresses sea clutter. Echoes received

from stable targets such as ships appear on the screen at almost the same

position every rotation of the antenna. On the other hand, unstable echoes such

as sea clutter appear at random positions.

To distinguish real target echoes from sea clutter, echoes are averaged over

successive picture frames. If an echo is solid and stable over successive frames,

it is presented in its normal intensity. Sea clutter is averaged over successive

scans and its brilliance reduced, making it easier to discriminate real targets

from sea clutter.

Echo averaging uses scan-to-scan signal correlation technique based on the

true motion over the ground of each target. Thus, small stationary targets such

as buoys will be shown while suppressing random echoes such as sea clutter.

True echo averaging is not however effective for picking up small targets running

at high speeds over the ground.

Note 1: Do not use the echo averaging function under heavy pitching and

rolling; loss of targets can result.

Note 2: Echo averaging can be used without a heading sensor. For further

details, contact your dealer.

Note 3: Echo averaging requires heading, position and speed data.

To properly use the echo averaging function, it is recommended to first suppress

sea clutter with the A/C SEA control. Then, do as follows:

1. Roll the trackball to choose the PICTURE box at the left side of the display.

2. Push the right button to show the PICTURE menu.

3. Roll the wheel to choose 3 ECHO AVERAGE and then push the wheel or the

left button.

high-speed craft, you should use “2” together with Wiper.

1.28 Target Trails

The trails of the radar echoes of targets may be displayed in the form of

synthetic afterglow. Target trails are chosen either relative or true and may be

sea or ground stabilized. True motion trails require a compass signal and own

ship speed input.

1.28.1 True or relative trails

You may display echo trails in true or relative motion (only true trail on TM).

Relative trails show relative movements between targets and own ship. True

motion trails require a gyrocompass signal and own ship speed input to cancel

out own ship's movement and present true target movements in accordance with

their over-the-ground speeds and courses.

1. RADAR OPERATION

1.33 Automatic Picture Setup According to

Navigation Purpose

Every time your navigating environment or task changes, you must adjust the

radar, which can be a nuisance in a busy situation. Instead of changing radar

settings case by case, it is possible to assign the function keys to provide

optimum settings for often encountered situations.

The radar's internal computer offers several picture setup options to be assigned

to each function key for your specific navigating requirements. For instance, one

of the functions is assigned the buoy detecting function and labeled SHIP on the

on the PICTURE box. By choosing SHIP, the radar will be instantly set for

optimum detection of ships.

Four user-programmable setups are also provided (labeled

PICTURE1-PICTURE4), so that you may have the radar automatically adjusted

to those conditions which are not covered by the provided setup options.

Below are the preset picture setup options provided with this radar.

*¹Models other than FAR-2157, FAR-2167DS

*²FAR-2157, FAR-2167DS only

Each picture setup option defines a combination of several radar settings for

achieving optimum setup for a particular navigating situation. Those involved are

interference rejector, echo stretch, echo average, noise rejector, automatic

anti-sea and anti-rain clutters, video contrast, pulselength and sea and radar

conditions.

Adjusting these features from the PICTURE menu changes the original function

key settings. To restore the original settings for a particular picture setup option,

it is necessary to choose the default setting. For this reason, we recommended

that you use the user-programmable function sets when frequent adjustment of

the radar picture is necessary.

Note 2: In the dual radar display, a guard zone set on the main radar is also

accommodated on the external radar. When the position of the antennas

for the main and external radars is different and the No. 2 guard zone is set

on a close-in range, the on-screen guard zone may be shifted slightly from

both the main radar antenna reference and external radar antenna

reference. Accordingly, on the dual radar display, the actual guard zone

area may be shifted slightly. For example, the guard alarm sounds against

a target which has almost entered the guard zone. The further the range

the smaller the shift; however, there is little shift with the No.1 guard zone

(3-6 mile range, fixed). Further, do not set a guard zone such that it

straddles a boundary line of the dual radar sector.

A guard zone cannot be set while the dual radar display is active. Set a zone

before activating the dual radar display.

2. RADAR OBSERVATION

2.1

General

2.1.1

Minimum and maximum ranges

Minimum range

The minimum range is defined by the shortest distance at which, using a scale of

1.5 or 0.75 nm, a target having an echoing area of 10 m²is still shown separate

from the point representing the antenna position.

It is mainly dependent on the pulselength, antenna height, and signal processing

such as main bang suppression and digital quantization. It is a good practice to

use a shorter range scale as far as it gives favorable definition or clarity of

picture. The IMO Resolution MSC.64(67) Annex 4 (Shipborne radar) and A.820:

1995 (High Speed Craft Radar) require the minimum range to be less than 50 m

and 35 m, respectively. This series of radars satisfy this requirement.

Maximum range

The maximum detecting range of the radar, Rmax, varies considerably

depending on several factors such as the height of the antenna above the

waterline, the height of the target above the sea, the size, shape and material of

the target, and the atmospheric conditions.

Under normal atmospheric conditions, the maximum range is equal to the radar

horizon or a little shorter. The radar horizon is longer than the optical one by

about 6% because of the diffraction property of the radar signal. The Rmax is

given in the following equation.

R_max= 2.2 x ( h1 + h2 )

where

Rmax: radar horizon (nautical miles)

h1:

h2 :

antenna height (m)

target height (m)

Radar horizon

Optical horizon

For example, if the height of the antenna above the waterline is 9 meters and the

height of the target is 16 meters, the maximum radar range is;

R_max= 2.2 x ( 9 + 16 ) = 2.2 x (3 + 4) = 15.4 nm

It should be noted that the detection range is reduced by precipitation (which

absorbs the radar signal).

2. RADAR OBSERVATION

X-band and S-band

In fair weather, the equation on the previous page does not give a significant

difference between X- and S-band radars. However, in heavy precipitation

condition, an S-band radar would have better detection than an X-band radar.

Radar resolution

There are two important factors in radar resolution (discrimination): bearing

resolution and range resolution.

Bearing resolution

Bearing resolution is the ability of the radar to display as separate pips the

echoes received from two targets which are at the same range and close

together. It is proportional to the antenna length and reciprocally proportional to

the wavelength. The length of the antenna radiator should be chosen for a

bearing resolution better than 2.5° (IMO Resolution). This condition is normally

satisfied with a radiator of 1.2 m (4 ft) or longer in the X-band. The S-band radar

requires a radiator of about 12 feet (3.6 m) or longer.

Range resolution

Range resolution is the ability to display as separate pips the echoes received

from two targets which are on the same bearing and close to each other. This is

determined by pulselength only. Practically, a 0.08 microsecond pulse offers the

discrimination better than 35 m as do so with all FURUNO radars.

Test targets for determining the range and bearing resolution are radar reflectors

having an echoing area of 10 m².

Bearing accuracy

One of the most important features of the radar is how accurately the bearing of

a target can be measured. The accuracy of bearing measurement basically

depends on the narrowness of the radar beam. However, the bearing is usually

taken relative to the ship’s heading, and thus, proper adjustment of the heading

line at installation is an important factor in ensuring bearing accuracy. To

minimize error when measuring the bearing of a target, put the target echo at the

extreme position on the screen by selecting a suitable range.

Range measurement

Measurement of the range to a target is also a very important function of the

radar. Generally, there are two means of measuring range: the fixed range rings

and the variable range marker (VRM). The fixed range rings appear on the

screen with a predetermined interval and provide a rough estimate of the range

to a target. The variable range marker’s diameter is increased or decreased so

that the marker touches the inner edge of the target, allowing the operator to

obtain more accurate range measurements.

2. RADAR OBSERVATION

2.2 False Echoes

Occasionally echo signals appear on the screen at positions where there is no

target or disappear even if there are targets. They are, however, recognized if

you understand the reason why they are displayed. Typical false echoes are

shown below.

Multiple echoes

Multiple echoes occur when a transmitted pulse returns from a solid object like a

large ship, bridge, or breakwater. A second, a third or more echoes may be

observed on the display at double, triple or other multiples of the actual range of

the target as shown below. Multiple reflection echoes can be reduced and often

removed by decreasing the gain (sensitivity) or properly adjusting the A/C SEA

control.

True

Multiple

Multiple echoes

Sidelobe echoes

Every time the radar pulse is transmitted, some radiation escapes on each side

of the beam, called “sidelobes.” If a target exists where it can be detected by the

side lobes as well as the main lobe, the side echoes may be represented on

both sides of the true echo at the same range. Side lobes show usually only on

short ranges and from strong targets. They can be reduced through careful

reduction of the gain or proper adjustment of the A/C SEA control.

A relatively large target close to your ship may be represented at two positions

on the screen. One of them is the true echo directly reflected by the target and

the other is a false echo which is caused by the mirror effect of a large object on

or close to your ship as shown in the figure below. If your ship comes close to a

large metal bridge, for example, such a false echo may temporarily be seen on

the screen.

SART (Search and Rescue Transponder)

2.3.1

SART description

A Search and Rescue Transponder (SART) may be triggered by any X-Band (3

cm) radar within a range of approximately 8 nm. Each radar pulse received

causes it to transmit a response which is swept repetitively across the complete

radar frequency band. When interrogated, it first sweeps rapidly (0.4 µs) through

the band before beginning a relatively slow sweep (7.5 µs) through the band

back to the starting frequency. This process is repeated for a total of twelve

complete cycles. At some point in each sweep, the SART frequency will match

that of the interrogating radar and be within the pass band of the radar receiver.

If the SART is within range, the frequency match during each of the 12 slow

sweeps will produce a response on the radar display, thus a line of 12 dots

equally spaced by about 0.64 nautical miles will be shown.

When the radar to the SART is reduced to about 1 nm, the radar display my

show also the 12 responses generated during the fast sweeps. These additional

dot responses, which also are equally spaced by 0.64 nautical miles, will be

interspersed with the original line of 12 dots. They will appear slightly weaker

and smaller than the original dots.

Showing SART marks on the radar display

This radar is equipped with a feature which optimally sets up the radar for SART

detection. This feature automatically detunes the radar receiver out of its best

tuning condition. This erases or weakens all normal radar echoes, but the SART

marks are not erased because the SART response signal scans over all

frequencies in the 9 GHz band. When the radar approaches the SART in

operation, the SART marks will enlarge to large arcs, blurring a large part of the

screen.

To set up for SART detection do the following:

1. Roll the trackball to choose the MENU box and then push the wheel or the

2. RADAR OBSERVATION

2.3.3

General remarks on receiving SART

SART range errors

When responses from only the 12 low frequency sweeps are visible (when the

SART is at a range greater than about 1 nm), the position at which the first dot is

displayed may be as much as 0.64 nm beyond the true position of the SART.

When the range closes so that the fast sweep responses are seen also, the first

of these will be no more than 150 meters beyond the true position.

Radar bandwidth

This is normally matched to the radar pulselength and is usually switched with

the range scale and the associated pulselength. Narrow bandwidths of 3-5 MHz

are used with long pulses on long range scales and wide bandwidths of 10-25

MHz with short pulses on short ranges.

A radar bandwidth of less than 5 MHz will attenuate the SART signal slightly, so

it is preferable to use a medium bandwidth to ensure optimum detection of the

SART.

Radar side lobes

As the SART is approached, side lobes from the radar antenna may show the

SART responses as a series of arcs or concentric rings. These can be removed

by the use of the anti-clutter sea control although it may be operationally useful

to observe the side lobes as they may be easier to detect in clutter conditions

and also they will confirm that the SART is near to own ship.

RACON

A RACON is a radar beacon which emits radar receivable signals in the radar

frequency spectrum (X- or S-band). There are several signal formats; in general,

the RACON signal appears on the radar screen as a rectangular echo

originating at a point just beyond the position of the radar beacon. It has a Morse

coded pattern. Note that the position on the radar display is not accurate.

3. ARP OPERATION

3.1

Usage Precautions

• This function is designed to meet the IMO requirements of both ARPA and

ATA, and the desired function is selected during the installation of the

equipment. For sake of brevity, this manual uses “ARP” when referring to

ARPA or ATA.

• The plotting accuracy and response of this ARP meets IMO standards.

Tracking accuracy is affected by the following:

• Tracking accuracy is affected by course change. One to two minutes is

needed to restore vectors to full accuracy after an abrupt course change.

(The actual amount depends on gyrocompass specifications.)

• The amount of tracking delay is inversely proportional to the relative speed

of the target. Delay is on the order of 15-30 seconds for high relative

speed; 30-60 seconds for low relative speed.

• The data generated by this ARP are intended for reference only. Refer to

official nautical charts for detailed and up-to-date information.

• A target measuring 800 m or more in the radial or circumferential direction is

regarded as a landmass and not acquired or tracked. Echoes smaller than

800 m are regarded as targets to be tracked.

3.4 Entering Own Ship's Speed

The ARP requires own ship's speed and heading data. The speed can be STW,

BT, SOG or echo-referenced speed (based on 3 max. stationary objects).

Manual input is also possible.

For automatic or manual input, see paragraph 1.13. For echo-referenced speed

input follow the procedure below.

3.4.1

Echo-referenced speed input

The use of echo-referenced speed is recommended when:

• The speed log is not operating properly or not connected to the radar.

• The vessel has no device which can measure ship's leeward movement

(Doppler sonar, speed log, etc.) when leeward movement can not be

disregarded.

If you select echo-referenced speed, the ARP calculates own ship's speed

relative to a fixed reference target. The number of targets may be 1, 2 or 3. They

appear as tracked targets, each shown in a small circle. When a plural of objects

are selected, the mean value is used for stabilization and speed.

1. With the cursor inside the effective display area, roll the wheel to display

“REF MARK / EXIT” in the guidance box.

2. Select a small fixed island or any radar prominent point located at 0.2 to 24

nm from own ship.

3. Roll the trackball to place the cursor (+) on the target selected at step 2.

Notes on speed input by reference target

• When the reference target is lost or goes out of the acquisition range, the

reference target mark blinks and the speed reads “*.*” Select a different

reference target in this case.

• When all targets are deleted, the reference target mark is also deleted and the

target-based speed becomes invalid. The speed is indicated as KTBT where

BT means Bottom Track (speed over ground).

• Reference targets may be marked with a vector. This can be done with 3 REF

Meaning

Symbol

Immediately after acquisition, this plotting symbol is shown in

broken lines.

Within 20 scans (3 s for HSC with antenna running at 42 rpm)) of

the antenna after acquisition, a vector appears to show a trend of

movement.

Within 60 scans (20 scans for HSC with antenna speed of 42 rpm)

of the antenna after acquisition, the plotting symbol changes to a

small circle, indicating steady-state tracking condition.

Note 1: For successful acquisition, the target to be acquired should be within 0.2

to 32 nm from own ship and not obscured by sea or rain clutter.

Note 2: When the capacity for manual acquisition is reached, the message

“TARGET-FULL(MAN)” is displayed at the screen bottom. Cancel

tracking of non-threatening targets if you wish to acquire additional

targets manually.

Note 3: Target number is normally not shown. On the A, B, C and W type radars

it appears when the cursor is placed on an ARP symbol.

CAUTION

Target Swap

When a target being tracked nears another

target being tracked, the targets may be

"swapped". When two targets acquired

either automatically or manually come close

to each other, one of the two may become

a Lost Target. Should this happen, manual

re-acquisition of the Lost Target may be

required after the two have separated.

Displaying Target Data

The ARP mode provides the full functionality of ARP as required by the IMO

Resolution A.823(19) and IEC 60972-1, including display of range, bearing,

course, speed, CPA and TCPA of all plotted targets.

In head-up and head-up true bearing modes, target bearing, course and speed

shown in the upper-right target data field become true (suffix “T”) or relative

(suffix “R”) to own ship in accordance with the true/relative vector setting. In

north-up, course-up and true motion modes, the target data field always displays

true bearing, true course and speed over the ground.

3.8.1

Displaying individual target data

COG/SOG (in case of GPS): Course and speed are displayed for the selected

target with suffix “T” (True) or “R” (relative). For manual speed input, CSE/STW

are shown.

CPA/TCPA: CPA (Closest Point of Approach) is the closest range a target will

approach to own ship. TCPA is the time to CPA. Both CPA and TCPA are

automatically calculated. When the CPA has passed clear of own ship, it is

indicated by a TCPA with a negative (-) sign. TCPA is counted to 99.9 min and

beyond this, it is indicate as TCPA> -99.9MIN.

BCR/BCT: BCR is the closest range at which the chosen target is predicted to

cross your ship’s bow. BCT is the time at which the chosen target is predicted to

cross your ship’s bow.

Vector Modes

Target vectors can be displayed relative to own ship's heading (Relative) or north

3.9.1

Description of vectors

Ground stabilization and sea stabilization

Target vectors can be ground stabilized or sea stabilized. Sea stabilization is a

mode where own ship and all targets are referenced to the sea using a compass

heading and single axis log water speed inputs in the True Motion mode. Ground

stabilization is a mode where own ship and all targets are referenced to the

ground using the ground track or set and drift inputs. If the accuracy seems

unsatisfactory, enter the set and drift correction. Note that set and drift should

not be used when the radar is displaying AIS targets.

True vector

In the true motion mode, all fixed targets such as land, navigational marks and

ships at anchor remain stationary on the radar screen with vector length zero.

But in the presence of wind and/or current, vectors appear on fixed targets

representing the reciprocal of set and drift affecting own ship unless set and drift

values are properly entered.

triangle and flashes together with its vector.

Provided that this feature is used correctly, it will help prevent the risk of collision

by alerting you to threatening targets. It is important that GAIN, A/C SEA, A/C

RAIN and other radar controls are properly adjusted.

CPA/TCPA alarm ranges must be set up properly taking into consideration the

size, tonnage, speed, turning performance and other characteristics of own ship.

Note: The reference point for CPA/TCPA calculation may be chosen from

antenna position or conning position. For further details, see paragraph

1.50.

3.13 Setting a Guard Zone

When a target transits the operator-set guard zone, the buzzer sounds and the

indication GUARD appears (in red) at the screen bottom. The target causing the

warning is clearly indicated with an inverted flashing triangle. The guard zone

also functions as an automatic acquisition area when automatic acquisition is

active. Any targets entering the zone will be automatically acquired.

3.13.1 Activating the guard zone

One or two guard zones may be selected. The No. 1 guard zone is available

between 3 and 6 nm and No. 2 guard zone can be set anywhere when the No. 1

zone is already in use. The ARP/AIS guard zone’s lines are white and dashed so

as to distinguish them from the radar guard alarm.

The procedure below shows how to set a guard zone, using the example at the

bottom of the page.

1. Roll the trackball to choose one of the GZ (GUARD ZONE) boxes at the right

side of the screen.

GZ 1

Guard zone status

GZ 2

Blank: GZ off

SET:

Set guard zone

WORK: Guard zone active

SLEEP: Guard zone "asleep"

GZ boxes

2. Push the left button. The GZ box now reads “GZx SET.”

3. Roll the trackball to place the cursor on point A and then push the left button.

4. Roll the trackball to place the cursor on point B and then push the left button.

The GZ box now reads “GZx WORK.”

0.5-1 nm

Target in guard zone is

marked by inverted

flashing triangle.

If you are setting a polygon guard zone with GZ2, set at least three points. Press

the right button to finish. Note that the status indication should be WORK or

SLEEP to set GZ2.

3. ARP OPERATION

When an ARP or AIS target violates the guard zone, the message “GUARD”

appears (in red) at the right side of the display and the offending target is

marked with an inverted triangle. Further, the AIS display is automatically turned

on.

Note 1: If you wish to create a guard zone having a 360-degree coverage

around own ship, set point B in almost the same direction (approx. ±3°)

as point A and then push the left button.

Note 2: If the range scale is changed to less than half of the guard zone, the GZ

box reads “GZx OUT.” If the left button is pushed in this state, the guard

alarm zone goes into “sleep” state and the guidance box reads “GZ

WORK L = DELETE.”

Note 3: The default guard zone is fan shaped. It may also be a polygon having

3-10 points. For details, see paragraph 3.13.5.

Note 4: Two more alarm zones (No. 1 and No. 2 Guard Alarm Zones) may be

added in addition. This means a maximum 4 alarm zones are available

at a time. ARP symbols are not changed to inverted triangles in the

guard alarm zone, only those in guard zone do so.

3.13.2 Sleeping, deactivating a guard zone

1. Roll the trackball to choose the appropriate GZ box.

2. Sleep or deactivate the guard zone as appropriate:

Sleep guard zone: Push the left button momentarily to remove the guard

zone from the screen. The indication in the GZ box changes from “GZx

WORK” to “GZx SLEEP.” To reactivate and display the guard zone, repeat

this procedure to display “GZx WORK.”

Deactivate guard zone: Push and hold down the left button until the GZ box

goes blank.

3.13.3 Acknowledging the guard zone alarm

Visual (COLLISION) and audible alarms are generated a target falls with a

preset limits. To acknowledge the audible alarm, press the [ALARM ACK] key, or

choose the ALARM ACK box and then push the left button.

Guard zone alarm

Visual (“GUARD”) and audible alarms are generated when a target transits the

operator-set guard zone. To acknowledge and silence the guard alarm, press the

[ALARM ACK] key, or choose the ALARM ACK box and then push the left button.

Lost target alarm

When the system detects a loss of a tracked target, the target symbol becomes

a flashing diamond ( ) and the label “LOST” appears at the screen bottom. At

the same time, an audible alarm is produced for one second.

To acknowledge and silence the lost target audible alarm, press the [ALARM

ACK] key, or choose the ALARM ACK box and then push the left button. Then,

the lost target mark disappears.

3. ARP OPERATION

3.15 Trial Maneuver

The trial maneuver feature simulates the effect on all tracked targets against

own ship's maneuver without interrupting the updating of target information. It is

available for use with the ARPA function; it is inoperative on the ATA.

3.15.1 Types of trial maneuvers

There are two types of trial maneuvers: static and dynamic.

Dynamic trial maneuver

A dynamic trial maneuver displays predicted positions of the tracked targets and

own ship. You enter own ship's intended speed and course with a certain “delay

time.” Assuming that all tracked targets maintain their present speeds and

courses, the targets' and own ship's future movements are simulated in

one-second increments indicating their predicted positions in one-minute

intervals as illustrated below.

The delay time represents the time lag from the present time to the time when

own ship will actually start to change her speed and/or course. You should

therefore take into consideration own ship's maneuvering characteristics such as

rudder delay, turning delay and acceleration delay. This is particularly important

on large vessels. How much the delay is set the situation starts immediately and

ends in a minute.

In the example shown below, own ship will advance straight ahead (even after a

maneuver) for a delay time of 5 minutes and then alters speed and course until

operator-specified intended speed and course are achieved (position OS7 in this

example).

OS8

OS7

OS6

OS5

Dynamic trial maneuver

Note that once a dynamic trial maneuver is initiated, you cannot alter own ship's

trial speed, course or delay time until the trial maneuver is terminated.

3. ARP OPERATION

Static trial maneuver

A static trial maneuver displays only the final situation of the simulation. If you

enter the same trial speed, course and delay time under the same situation as in

the aforementioned example of dynamic trial maneuver, the screen will instantly

show position OS7 for own ship, position A7 for target A and position B7 for

target B, omitting the intermediate positions. Thus, the static trial maneuver will

be convenient when you wish to know the maneuver result immediately.

Note: For accurate simulation of ship movements in a trial maneuver, own ship's

characteristics such as acceleration and turning performance should be

properly set in initial settings during the installation.

3.15.2 Performing a trial maneuver

To perform a trial maneuver, do the following:

1. Roll the trackball to choose the MENU box at the right side of the screen and

then push the left button.

collision course with own ship (that is, the target ship comes within preset

CPA/TCPA limits), the target plotting symbol changes to a triangle and

flashes. If this happens, change own ship's trial speed, course or delay time

to obtain a safe maneuver. The trial maneuver is automatically terminated

and the normal radar picture is restored three minutes later.

3.17 Criteria for Selecting Targets for Tracking

The FURUNO ARP video processor detects targets in midst of noise and

discriminates radar echoes on the basis of their size. Target whose echo

measurements are greater than those of the largest ship in range or tangential

extent are usually land and are displayed only as normal radar video. All smaller

ship-sized echoes which are less than this dimension are further analyzed and

regarded as ships and displayed as small circles superimposed over the video

echo.

When a target is first displayed, it is shown as having zero true speed but

develops a course vector as more information is collected. In accordance with

the International Marine Organization Automatic Radar Plotting Aid (IMO ARP)

requirements, an indication of the motion trend should be available within 20

scans of antenna and full vector accuracy within 60 scans. The FURUNO ARPs

comply with these requirements.

Acquisition and tracking

A target which is hit by five consecutive radar pulses is detected as a radar echo.

Manual acquisition is done by designating a detected echo with the trackball.

Automatic acquisition is done in the acquisition areas when a target is detected

5-7 times continuously depending upon the congestion. Tracking is achieved

when the target is clearly distinguishable on the display for 5 out of 10

consecutive scans whether acquired automatically or manually. Required

tracking facilities are available within 0.1-32 nm on range scales including 3, 6,

12 nm, full plotting information is available within one scan when the range scale

has been changed.

Targets not detected in five consecutive scans become “lost targets.”

Quantization

The entire picture is converted to a digital from called “Quantized Video.” A

sweep range is divided into small segments and each range element is “1” if

there is radar echo return above a threshold level, or “0” if there is no return.

The digital radar signal is then analyzed by a ship-sized echo discriminator. As

the antenna scans, if there are five consecutive radar pulses with 1’s indicating

an echo presence at the exact same range, a target “start” is initiated. Since

receiver noise is random, it is not three-bang correlated, and it is filtered out and

not classified as an echo.

The same is true of radar interference. Electronic circuits track both the closet

and most distant edges of the echo. At the end of the scanning of the echo, the

discriminator indicates the measured maximum range extent and total angular

extent subtended by the echo. If the echo is larger than a ship-sized echo in

range extent and/or angular width, adjusted as a function of range, it is declared

to be a coastline and the closet edge is put into memory as a map of the area.

3. ARP OPERATION

This land outline is used to inhibit further acquisition and tracking of ship-sized

echoes beyond the closest coast outline. Five consecutive scans of coastal

outline are retained in memory to allow for signal variation. All smaller echoes

are declared to be ship sized and the middle of the leading edge is used to

provide precise range and bearing coordinates of each echo on every scan. This

range/bearing data is matched to previous data and analyzed from scan-to-scan

for consistency. When it is determined to be as consistent as a real target,

automatic acquisition occurs and tracking is initiated. Continued tracking and

subsequent calculation develop the relative course and speed of the target.

The true course and speed of own ship are computed from own ship's gyro and

speed inputs, and the resulting course and speed of each tracked target is easily

computed by vector summing of the relative motion with own ship’s course and

speed. The resulting true or relative vector is displayed for each of the tracked

targets. This process is updated continually for each target on every scan of the

radar.

Qualitative description of tracking error

The FURUNO ARP accuracy complies with or exceed IMO standards.

Own ship maneuvers

For slow turns there is no effect. For very high turning rates (greater than

150°/minute, depending on gyro), there is some influence on all tracked targets

which last for a minute or two and then all tracked targets revert to full accuracy.

Other ship maneuvers

Target ship courses, lag 15 to 30 seconds at high relative speed, or 3 to 6

seconds at low (near 0) relative speed. It is less accurate during a turn due to lag,

but accuracy recovers quickly.

3. ARP OPERATION

3.18 Factors Affecting ARP Functions

Sea returns

If the radar anti-clutter control is adjusted properly, there is no serious effect

because distant wave clutter, not eliminated by this control, is filtered out by

more than one bang correlation and scan-to-scan matching of data.

Rain and snow

Clutter can be acquired and tracked as targets. Adjust the A/C RAIN control. If it

is heavy rain, switch to S-band if provided, or switch on the interference rejector

on the radar. If heavy clutter still exists, switch to manual acquisition. Accuracy

can be affected.

Low clouds

Usually no effect. If necessary, adjust the A/C RAIN control.

Non-synchronous emissions

No effect.

Low gain

Insufficient or low radar receiver gain will result in some targets not being

acquired at long distance. ARP display will be missing on one or more targets

that could only be visible if the radar sensitivity control (GAIN control) were

increased.

The setting of the correct radar receiver gain is not critical but the target should

be on the radar PPI and be clearly visible and well defined.

Manual acquisition is done if a target is positively displayed more than once.

Automatic acquisition is done when the target is detected 5-7 times continuously.

Tracking is achieved when the target is detected five times (not necessarily

continuously) out of 10 scans. If not detected six times out of 10 scans, the

target will become a “lost target.” The ARP will acquire a radar echo that is

present once in every six antenna scans and continue tracking if 1 in 10.

Second trace echoes

When the radar beam is super refracted, strong echoes may be received at such

long ranges that they appear on a different timebase sweep than the transmitted

pulse. This gives an incorrect range indication. Second and third trace echoes

can be tracked if they are consistent enough to meet acquisition and tracking

criteria but target course and speed data will be in error.

3. ARP OPERATION

Blind and shadow sectors

Radar shadow or blind areas caused by obstructions aboard ship, for example,

funnels and masts, in the path of the radar beam can result in reduction of radar

beam intensity in that particular direction. This may eliminate the detection of

some targets. The ARP system will lose track of targets shortly after they are lost

on the radar picture and if they remain in a blind zone. These targets will

however be acquired and tracked when they pass out of the blind zone and

again present normal radar echo. The angular width and bearing of any shadow

sector should be determined for their influence on the radar. In certain cases

false echoes in the shadow sector cause the ARP system to acquire, track, and

vector them. Shadow sectors should be avoided.

Indirect echoes

A target at close range is usually picked up directly, but it can also be received

as reflection from a large, flat surface. This will result in the radar presenting two

or more echoes on the display, each at a different range. The ARP can acquire

and track the false echo if it is detected by five consecutive scans. Reduction in

radar gain can eliminate the multiple echoing but care should be taken as range

detection also will be reduced.

Radar interference

If interference is extreme due to another radar operating at close range, spiral

“dotting” and/or false targets may appear momentarily. The interference rejector

can clear the display.

To receive radar beacon or SART signals, turn on “SART” in the ECHO menu.

4. AIS OPERATION

The FURUNO AIS (Automatic Identification System) model FA-100 or FA-150

exchanges with other AIS-fitted ships all data and information required by the

SOLAS 1994 as amended. However, they are displayed in text form. By

interfacing the FA-100 or FA-150 with this radar, the AIS information is

graphically indicated together with the radar and ARP information.

This radar accepts position data fixed by WGS-84 geodetic datum. Set the

datum to WGS-84 on the EPFS (GPS, etc.) connected to this radar. If other type

of datum is input, the error message "DATUM" appears and the AIS feature is

inoperative.

4.10 Lost Target

A target is declared a lost target when it fails to produce data for six minutes or

five reporting intervals, whichever is the shorter. When this occurs, the target is

marked with the (flashing) lost target symbol and the indication “LOST” appears.

To acknowledge a lost target, press the [ALARM ACK] key or roll the trackball to

Note 1: If an ARP lost target mark is displayed when the [ALARM ACK] key is

pressed (or the ALARM ACK box is clicked) to acknowledge an AIS lost

target, the ARP lost target will also be erased.

Note 2: The AIS data transmission interval depends on target’s speed. For

example, the data is transmitted every 10 seconds on ship speed of 0 to

14 kt and every two seconds on the ship speed of more than 23 knots.

For details see the owner’s manual of the AIS.

You may choose what lost targets to sound the lost target alarm against as

4.12 Fusion of ARP and AIS Targets

An AIS-equipped ship is usually displayed by two symbols on the radar display.

This is because the AIS ship position is measured by a GPS navigator (L/L) on

that ship whereas the radar detects the same ship by PPI principle (range and

bearing relative to own ship radar antenna).

To avoid the presentation of two target symbols for the same physical target, the

“fusion” function is incorporated. If target data from AIS and from radar plotting

functions are available and if the fusion criteria is fulfilled, only the activated AIS

target symbol is presented.

1. Confirm that the ARP ACQ MODE box shows AUTO or AUTO MANU.

2. Roll the trackball to choose the MENU box and then push the left button.

3. Roll the wheel to choose 4 ARP•AIS and then push the left button.

General

The video plotter

• Plots own and other ships’ tracks. (Plotting of other ships’ tracks not available

on IMO type.)

• Enters waypoints nav lines and marks

• Records data onto memory cards (optional card interface required).

• It uses two types of memory cards, a memory card (RAM card) for storing own

ship and other ship’s tracks and marks, and a digital chart card (ROM card).

• 30 nav lines may be stored and each line may contain up to 30 waypoints.

Five nav lines may be simultaneously shown on the display. 200 waypoints are

available. Own ship and other ship tracks may be stored at a selected interval.

• Charts (B, C and W types) are superimposed on the radar picture without

disturbing the radar observation. The chart area is dependent on the radar

range in use.

5.2

Display Modes

This radar has two display modes: Radar and Radar + Video Plotter. Use the

DISPLAY MODE box to choose a mode. (When the video plotter mode is

displayed more than five seconds, the radar automatically goes into standby.)

Note 1: Display mode cannot be chosen when the menu is open. Close the

menu to choose a display mode.

Note 2: Only the radar display is available on the IMO-type radar.

Radar Map

A radar map is a combination of map lines and symbols whereby the user can

define and input the navigation data, route planning and monitoring data.

The radar map may contain 20,000 points of data. The map data can be

memorized to facilitate repeated use on a routine navigation area.

The user can create a radar map on-real time while using the radar for

navigation or at leisure time at anchor or while the radar is not being used. Place

of a map can be made for any waterways apart from the actual own ship

location.

All radar map functions are accessed from the radar display. To choose the radar

display, use the trackball to choose the DISPLAY MODE box and push the left

button to display “RADAR.” Then, follow the procedures in this section to create

a radar map.

Replacing the Fuse

The fuse at the rear of the processor unit

in the display unit protects the equipment

from overcurrent (overvoltage in case of

AC set) and equipment fault. If you cannot

turn on the power, first check the fuse.

Find the cause of the trouble before

replacing the fuse. Be sure to use the

proper fuse. Use of a wrong fuse can

seriously damage the equipment and void

the warranty.

WARNING

Use the proper fuse.

Use of a wrong fuse can result in damage

to the equipment or cause fire.

4. Longitude Error Table (on 96 nm range scale)

The longitude lines concentrate on the north pole and south pole, namely, 1 nm is

equivalent to 1 minute at 0 degree latitude, 2 minutes at 60 degrees latitude, 3 minutes at

70 degrees latitude and so on. For this reason, a longitude error occurs on the radar display.

For example, when own ship is at 60°N and 135°E, even if the cursor indication is 62°N and

139°E, the real cursor position is deviated to the left (west) side. The table below shows the

longitude error, represented from 0° to 90° at 96 nm from the radar center (own ship).
