FOREWORD
A Word to FCV-582L Owners
Features
Congratulations on your choice of the
FURUNO FCV-582L Color LCD Sounder.
We are confident you will see why the
FURUNO name has become synonymous
with quality and reliability.
The FURUNO FCV-582L is a dual-frequency
(50 kHz and 200 kHz) color LCD sounder.
Comprised of a display unit and a transducer,
the FCV-582Ldisplays underwater conditions
in 16 colors (including background) on a
bright 6.5-inch color TFT (Thin Film Tran-
sistor) LCD.
For over 50 years FURUNO Electric Com-
pany has enjoyed an enviable reputation for
innovative and dependable marine electron-
ics equipment. This dedication to excellence
is furthered by our extensive global network
of agents and dealers.
The main features of the FCV-582L are
• Compact design permits installation where
space is limited.
• Bright 6.5-inch color LCD with tempera-
ture compensated tone and brilliance con-
trol.
This equipment is designed and constructed
to meet the rigorous demands of the marine
environment. However, no machine can per-
form its intended function unless operated and
maintained properly. Please carefully read and
follow the recommended procedures for op-
eration and maintenance.
• Wide variety of display modes: bottom
lock, dual frequency, marker zoom, bottom
zoom, nav data and graphic display.
• Automatic function permits unattended
adjustment of range and gain. The range
scale and gain automatically change to dis-
play the bottom in reddish-brown on the
lower half of the screen.
• Navigation data display (requires naviga-
tion data input from external navigator)
provides position, course, speed, depth,
temperature and waypoint data indications.
• Alarms: Bottom, Fish (bottom-lock, nor-
mal), Temperature (within, over range set).
• A-scope display discriminates bottom fish,
vital for bottom trawler and trap users.
• Universal 10.2–31.2 VDC power supply
consuming less than 20 W power.
We would appreciate hearing from you, the
end-user, about whether we are achieving our
purposes.
Thank you for considering and purchasing
FURUNO equipment.

PRINCIPLE OF OPERATION
The FCV-582L determines the distance be-
tween its transducer and underwater objects
such as fish, lake bottom or seabed and dis-
plays the results on its screen. It does this by
utilizing the fact that an ultrasonic wave trans-
mitted through water travels at a nearly con-
stant speed of 4800 feet (1500 meters) per
second. When a sound wave strikes an un-
derwater object such as fish or sea bottom,
part of the sound wave is reflected back to-
ward the source. Thus by calculating the time
difference between the transmission of a
sound wave and the reception of the reflected
sound wave, the depth to the object can be
determined.
The entire process begins in the display unit.
Transmitter power is sent to the transducer as
a short pulse of electrical energy. The electri-
cal signal produced by the transmitter is con-
verted into an ultrasonic signal by the
transducer and transmitted into the water.Any
returning signals from intervening objects
(such as a fish school) are received by the
transducer and converted into an electrical sig-
nal. The signals are then amplified in the am-
plifier section, and finally, displayed on the
screen.
The picture displayed is made up of a series
of vertical scan lines, one for each transmis-
sion. Each line represents a snapshot of what
has occurred beneath the boat. Series of snap-
shots are accumulated side by side across the
screen, and the resulting contours of the bot-
tom and fish between the bottom and surface
are displayed.

The graphic display 1 provides analog and
digital displays of cross-track error (XTE),
course and bearing. It is useful for monitor-
ing progress toward a waypoint. The XTE
scale in the center of the display, graduated in
increments of 0.1 nm, shows cross-track er-
ror, the dird/Xion and distance the boat is off
course. In the example below the XTE marker
(red) shows the boat is off course by 0.2 nm
starboard. Therefore you would steer left by
the same distance to return to course.

1.6 Selecting Display Range
The basic range may be shifted with the [+]
and [–] keys. The shift display window, which
appears when the [+] or [–] key is operated,
shows current shift amount. Note that the
SHIFT keys and RANGE control are inop-
erative in automatic operation.
The basic range and range shifting functions
used together give you the means to select the
depth you can see on the screen. The basic
range can be thought of as providing a “win-
dow” into the water column and range shift-
ing as moving the “window” to the desired
depth. Note that the RANGE control is inop-
erative in automatic operation. (See the next
page for details.)
SHIFT

Note: The maximum shift range is 2500 feet
(500 m). However, the actual range will de-
pend on underwater conditions. In the worst
case echoes will not appear.

1.7 Adjusting the Gain
The GAIN control adjusts the sensitivity of
the receiver. Adjust the control so that a slight
amount of noise remains on the screen. Gen-
erally, use a higher gain setting for greater
depths and a lower setting for shallower wa-
ters. Note that the GAIN control is inopera-
tive in automatic operation.

1.8 Automatic Operation
1.9 Selecting Picture Advance
Speed
Automatic operation is useful when you are
preoccupied with other tasks and do not have
time to adjust the display.
The picture advance speed determines how
quickly the vertical scan lines run across the
screen. When selecting a picture advance
speed, keep in mind that a fast advance speed
will expand the size of the fish school hori-
zontally on the screen and a slow advance
speed will contract it.
How it works
The automatic function automatically selects
the proper gain and range scale according to
depth. It works as follows:
1. Press the ZOOM and SIG LEV keys to-
gether. The following display appears.
• The range changes automatically to locate
the bottom on the lower half of the screen.
It jumps to one step shallower range when
bottom echoes reach a halfway point of the
full scale from top and to one step deeper
range when they come to the lower edge
of the scale.
• The gain is automatically adjusted to dis-
play the bottom echo in reddish-brown (de-
fault color arrangement).

• Clutter level (on the User menu), which
suppresses low level noise, is automatically
adjusted.
Figure 1-20 Picture advance

The fractions in the menu denote number
of scan lines produced per transmission.
For example, 1/8 means one scan line is
produced every 8 transmissions. STOP
freezes the display and it is convenient for
observing an echo.
Two types of automatic modes
Two types of automatic modes are available:
cruising and fishing. Cruising is for tracking
the bottom; fishing is for searching fish
schools. Since cruising uses a higher clutter
rejection setting than fishing, it is not recom-
mended for fish detection – weak fish echoes
may be deleted by clutter rejection.
2. Press the [▲] or [▼] key to select speed
desired.

2.5 TVG Level
2.6 Echo Offset
TVG (Time Varied Gain) compensates for
propagation attenuation of the ultrasonic
waves. It does this by equalizing echo pre-
sentation so that fish schools of the same size
appear in the same density in both shallow
and deep waters. In addition, it reduces sur-
face noise. Note that if the TVG level is set
too high short range echoes may not be dis-
played.
The echo offset feature functions to compen-
sate for too weak or too strong echo level. If
the on-screen echo level appears to be too
weak or too strong and the level cannot be
adjusted satisfactorily with the GAIN control,
do the following to adjust echo level:
1. Turn on the power while pressing any key.
2. Press the SIG LEV key three times. The
start-up screen appears and shortly there-
after the ECHO OFFSET display appears.

INTERPRETING THE DISPLAY
3.1 Zero Line
3.3 Bottom Echo
The zero line (sometimes referred to as the
transmission line) represents the transducer’s
position, and moves off the screen when a
deep phased range is used.
Echoes from the bottom are normally the
strongest and are displayed in reddish-brown
color (in default color arrangement) but the
color and width will vary with bottom com-
position, water depth, frequency, sensitivity,
etc.
Zero
line
In a comparatively shallow depth, a high gain
setting will cause a second or sometimes a
third or a fourth echo to be displayed at the
same interval between them below the first
echo trace. This is because the echo travels
between the bottom and the surface twice or
more in shallow depths.
Shift
The color of the bottom echo can be used to
help determine the density of the bottom ma-
terials (soft or hard). The harder the bottom,
the wider the trace. If the gain is set to show
only a single bottom echo on mud, a rocky
bottom will show a second or third bottom re-
turn. The range should be chosen so the first
and second bottom echoes are displayed when
bottom hardness is being determined.
Figure 3-1 Zero line
3.2 Fish School Echoes
Fish school echoes will generally be plotted
between the zero line and the bottom. Usu-
ally the fish school/fish echo is weaker than
the bottom echo because its reflection prop-
erty is much smaller compared to the bottom.
The size of the fish school can be ascertained
from the density of the display.

3.4 Surface Noise/Aeration
Surface noise
Caused by
aerated water
When the waters are rough or the boat passes
over a wake, surface noise may appear near
the zero line. As surface turbulence is acous-
tically equivalent to running into a brick wall,
the bottom echo will be displayed intermit-
tently. Similar noise sometimes appears when
a water temperature difference (thermocline)
exists. Different species of fish tend to prefer
different temperature zones, so the ther-
mocline may be useful to help identify target
fish. 200 kHz tends to show shallow ther-
moclines better than 50 kHz.
Thermocline
In rough waters the display is occasionally in-
terrupted due to below-the-ship air bubbles
obstructing the sound path. This also occurs
when the boat makes a quick turn or reverses
movement. Lowering the picture advance
speed may reduce the interruption. However,
reconsideration of the transducer installation
may be necessary if the interruption occurs
frequently.
