the original digital document and scanning an existing manual. Because of this, there are many

less then perfect pages and hand written comments.

As Pioneer is constantly working towards providing the best possible documentation for our

products, there may be an improved version of this document available. Please contact your

To turn off the power, use the POWER switch - of the unit, the RS-232C control, or wired rem ote control (optional). (If turned

off using the m ain POWER switch or by disconnecting the power cable from the outlet, the settings of the above = to @

switches and the state of the TV SYSTEM and convergence m em ory will not be recorded on the m em ory.)

Consequently when starting up or stopping the whole system by AC ON/OFF in setup conditions for a dem onstration, it is

necessary to turn off the power using the above m ethod to record each setting in the m em ory.

(Refer to "CHAPTER 4. ADJ USTMENTS, (5)Equipm ent Required for Adjustm ents".)

INSTALLATION AND ASSEMBLY

(9) Ventilation for system

The ventilation m ethod differs according to where the system is installed. The following shows how to provide ventilation for

the units according to the place of installation. Refer to these and keep the installation condition in the previous section [(8)

Tem perature and Hum idity] at the system .

But when installing your unit, consult your dealer.

1When there are no walls on all sides (within 1m )

As shown in Fig. 3-3, attach the top panel, side panel, and rear panel.

(Note)

When attaching the rear panel, be careful not to block the vents for the fan of the projection unit.

2When there is a wall at the back *

As shown in Fig. 3-5, m ount a large fan to the top panel, provide vents for inhaling air at the bottom panel to blow out air

inside. Always leave m ore than 300 m m between the wall and the back of the unit.

(Fig. 3-5)

(Fig. 3-3)

3When blocking the bottom (when placing the projection unit on the floor directly) *

Sam e as 1. (Fig. 3-6)

<Note>

*: There should be no obstacles within the 1m area of the

unit except for the rear and bottom . If this condition is

not followed, construct your own ventilation system

(large fan, low tem perature by air-conditioning, etc.)

according to the site of use.

(Fig. 3-6)

INSTALLATION AND ASSEMBLY

(10) Condensation

One problem that occurs in the winter season is "Condensation". When the tem perature of the room in which the m ulti-

projection unit system is installed rises suddenly, condensation occurs on the screen and lens, thereby the system cannot

display its best perform ance. In such cases, turn off the power once, leave the system off for one hour, and turn on the power

again. Increasing the room tem perature gradually is another m ethod.

INSTALLATION AND ASSEMBLY

4 3P Plug

The power cord of this unit has a 3P plug. This is to prevent electric shocks caused by leaked currents. Always connect it to a

3P outlet.

5 Leak Breaker

The unit is incorporated with the power line filter to reduce noise. Therefore a 0.5 m A leakage current will flow with each unit.

If a leak breaker is equipped, check that its sensitive level is above the total leakage current of the system .

Also calculate each unit such as im age transm ission unit, etc. as 0.5 m A.

It is extrem ely dangerous to supply power from existing wall outlets, etc.

Position the final outlet connected to each unit of this system as near as possible to the system .

Set the current capacity slightly greater-about m ore than 25% of the total consum ption power.

(15) Cables Used

Use coaxial cables. Norm ally use a 3C-2V for less than 20m long. Use 5C-2V for greater lengths. 5C-2V is recom m ended for

high-vision.

Adjust the length of the cables. The distance between the transm ission system and m ulti-projection unit should be as short as

possible. When the distance is great, consider the thickness of the cable and electrical com pensation carefully.

The lim it is as shown when using the cables to connect the transm ission final output term inal and the system .

3C-2V: 15m

5C-2V: 30m

To use a longer cable, the VIDEO signal m ust be corrected.

(16) Sem i-outdoor Installation

This system is basically designed for use indoors. However, if it has to be installed outdoors, take note of the following.

•

Waterproof and rustproof m easures

Tem perature difference and hum idity difference

Light on the screen (So that it is not exposed to direct sunlight.)

Wind containing salt

(17) Precautions for Use of User-Obtained Parts

It is recom m ended that Pioneer products be used for the projection stand, m ount unit, etc. Users obtaining these parts sepa-

rately by them selves should take note of the following.

• When obtaining stands and m ount units separately, m ake sure that the system can be installed horizontally. Also calculate

strength properly and take adequate m easures against tilting of the screen. If the recom m ended stand and m ount unit are

not used, Pioneer will bear no responsibility whatsoever for accidents and injuries incurred due to incom plete connections

and m ounting, natural disasters, etc.

• When m ounting top board, side board, rear panel obtained separately, use the holes for m ounting the Pioneer stand and

projection fram e. (Refer to Fig. 3-39)

If rem oving the screen after installing the system , the person m ust go behind the screen (diagonally shaded part of the

figure). Therefore when insetting the unit in the wall, careful take this into account before installation.

Screen

(Fig. 3-43)

• When fixing the screen into the wall, space for placing your hand inside the wall at the top, bottom , right, and left will be

required in addition to the above in order to attach and rem ove the screen.

(2) Diagonal installation

• This system cannot be placed facing upwards or downwards and diagonally. Always place it horizontally.

However, Multiprojection unit (RM-V4000NA/V5000NA) alone can be tilted at the up to 45 deg. Installation of special order

screens and cabinets should also becom e possible in the near future.

(3) Architrave processing

CHAPTER 4. ADJ USTMENTS

1. ADJ USTMENT PREPARATIONS

(1) Wiring

1 Connection of Pow er Supply

•

The power supply can be connected to up to 3 units in a series using the AC outlets of Multi projection units. Connect the

three units as one system to the external outlet.

The AC plug of Multi projection unit is a 3P with a ground pin. When connecting it to a norm al outlet, use an exclusive 3P AC

adapter.

The AC plug of Multi projection unit is a 3P with a ground pin. To prevent electric shocks, connect the ground pin to the

ground when connecting the power supply.

2 Connection of signal cable

•

Use coaxial cables. Norm ally, if less than 15m , use 3C-2V. If less than 30m , use 5C-2V.

The signal transm ission equipm ent and Multi projection units should be as close as possible to each other.

3 Connection of ABL link cable

•

By connecting the ABL link cables in cascade form , control signals (RS-232C, rem ote control signal) can be transm itted to all

the units.

Link cable

Rem ote control unit

(Up to 16 units can be operated using the rem ote control unit at one tim e using the link cable.)

(2) Wiring Handling

•

Except for short-term installations such as events, etc., in norm al long-term installations, adjust the length of the wiring

appropriately taking into consideration the overall route to be wired.

•

Make sure the connection term inals are not subjected to direct weight and force. Tie the wires up in short-term use and bind

them up properly in long-term use.

(3) Aging

•

After turning on the power, input the 100% white signal or m oving im ages, and perform aging until Multi projection unit

stabilizes (about 1 hour). If adjustm ents are perform ed without aging, as it takes tim e until Multi projection unit will warm

up and stabilize, convergence and white balance will becom e incorrect.

ADJ USTMENTS

(2) TV System

The TV system determ ines the control of the whole unit (convergence, OSD display select, video system select, deflection)

according to the signal input.

Set it according to the signal input.

When TV SYSTEM is set to AUTO

•

The m ode is autom atically set to NTSC or PAL according to the input signal (NTSC/PAL).

When the TV SYSTEM is set to NTSC

The m ode is set to NTSC regardless of the input signal.

When the TV SYSTEM is set to PAL

The m ode is set to PAL regardless of the input signal.

•

[Precaution to use]

Norm ally, the TV SYSTEM is set to AUTO. If the signals cannot be differentiated between NTSC and PAL (or they are differen-

tiated incorrectly : VCR signal repeatedly dubbed or part of CATV converter, etc.), the TV SYSTEM is set to NTSC or PAL

according to the input signal.

When the input signal is NTSC or PAL, and the TV SYSTEM is set to NTSC or PAL, it can enable the input to be switched

sm oothly (little screen noises), and prevent signals from being differentiated incorrectly due to signal disturbances and cuts.

In som e cases, even if the sam e TV form at is used, m ore than two types of convergence data will be required. (For exam ple,

when there are signal phase differences for every input source, etc.) In such cases, use two types of m em ories. Switch them

using the personal com puter.

(6) Giving IDs

When several Multi projection units are used to com pose the 9 screens or 16 screens (m ulti-screen), the ID is used to differen-

tiate between Multi projection units. When the units are given IDs, by connecting the ABL link cable, com m ands can be

transm itted by specifying the ID, and it is possible to operate only Multi projection unit corresponding to that ID by rem ote

control operations.

6 LINEAR WHITE adjustm ent

When white peak signals such as WINDOW are input, due to the characteristics of the Blue CRT, there is a tendency for the

peak to becom e yellow com pared to other colors. The linear white adjustm ent is perform ed to correct this tendency.

Blue becom es weak when data is set to UP and strong when set to DOWN. If Linear White is added excessively, the ABL

voltage becom es unbalanced and the m edium lum inance of blue m ay be erased, etc.

Also m ake sure that the blue is not blur when MULTI ON is set because the top left and bottom left of the screen are affected

first.

7 ABL GAIN adjustm ent (White 100%)

The ABL GAIN adjustm ent adjusts the white 100% lum inance of a unit to other units after low lum inance and m edium lum i-

nance have been adjusted.

Norm ally, when white 100% is input, ABL is im posed and the current is controlled so that the current flowing in the CRT does

not exceed a certain level. Even if the current flowing in the CRT of each unit is the sam e, the difference in the characteristics

of each CRT will cause their lum inance to becom e inconsistent. The ABL GAIN adjustm ent converges this inconsistency. It

adjusts the ABL current flowing virtually.

In white 100% inputs, as the ABL works efficiently, the lum inance drops, when the ABL GAIN of a unit with high lum inance is

decreased, use this adjustm ent to adjust its lum inance to the other units.

Turn off the ABL in the adjustm ent.

Norm ally set the ABL GAIN to m axim um .

8 ABL LEVEL adjustm ent (White 100%)

The ABL LEVEL adjustm ent controls the inconsistency of the ABL control voltage of each unit when ABL is on.

[1] Set the ABL of all units to ON.

[2] Turn on and off the ABL of each unit to change the lum inance.

[3] For units whose lum inance becom es dark when ABL is ON, turn UP the ABL level and set to the point where the

lum inance stops changing by turning on and off the ABL.

[4] For units whose lum inance does not change, turn DOWN the ABL level to the point just before the lum inance

becom es dark.

[5] Perform steps (2) to (4) for all the units, change white from 0 to 100% and check that the ABL does not work

abnorm ally.

[5] Attach a new screen. While paying attention to the front and back, attach the fresnel lens.

(Flat side:The shiny side is for the projection unit side.)

[6] In the sam e way, attach the lenticular sheet while paying attention to the front and back.

(The shiny side is for the fresnel lens side.)

* When attaching the screen, past the adhesive double coated tape properly by rubbing the tape with your finger with

force.

[7] Paste a black vinyl tape around the edge of the screen. It can be pasted easily by placing the screen fram e on its side. As

shown in Fig. 5-6, paste the vinyl tape slightly protruding out on the edges of each screen and cut off the protruding parts.

Be careful not to scratch the lenticular sheet at this tim e.

[8] After peeling off all the adhesive double coated tape rem aining on the back of the panel or the fram e, paste the above

adhesive double coated tape to the fram e side. Make sure not to paste over the black vinyl tape.

[9] Peel off the released paper of the adhesive double coated tape and paste the panel along the tapped holes. Tighten the 12

screws.

[10] Finally, check that the screen will not com e off from its front and back.

2. When all panels have been rem oved, the top and right side of the screen will becom e free. Rem ove the screen by pulling

it out from the top right. (Fig. 5-9.)

Note:

The panel is fixed by adhesive double coated tape at the left side and bottom of the screen, but the lenticular sheet can

be rem oved relatively easily. As the Fresnel lens is secured firm ly, it cannot be rem oved easily just by pulling out

upwards to the right. To rem ove the Fresnel lens, pull it slowly upwards towards the right, and rem ove it as if opening

it like a door. (Fig. 5-10)

4. Mount the new screen. Mount the Fresnel lens while m aking sure not to m istake the front and back. (That which has a

shiny surface is the projection unit side.)

5. In the sam e way, attach the lenticular sheet while paying attention to the front and back. (The shiny side is the Fresnel

lens side.)

Notes

•

When attaching the screens, rub over the adhesive double coated tape with your finger firm ly from the outside to

adhere the tape firm ly onto the screen.

•

Pay careful attention to the front and back of the screen. If m ounted at the sides reversed, unnatural im ages will be

produced.

6. Attach the panels rem oved at step 1 in the reverse order as when they were rem oved.

Note

Insert each panel firm ly so that they fit the stoppers.

[3] Adjusting the screen angle finely

The angle of the screen can be adjusted finely (top, bottom , left and right) by inserting and rem oving cabinet spacers. Add

or rem ove spacers as desired.

Cabinet spacers are inserted between the screen and cabinet (two at the top, and two at the right). (Fig. 5.12)

OPERATIONS

Notes

•

To produce fine joint, the left side and bottom of the screen are secure with adhesive double coated tape. Make sure the

replaced screen is attached closely to the left and bottom sides of the panel. If not attached closely, the screen will discon-

nect from the panels when it expands and contracts according to tem perature and hum idity changes, or in the worst case,

drop off.

•

In replacem ents, m ake sure not to leave dust and dirt between the lenticular sheet and fresnel lens.

Take note of the front and back of the screen. Unnatural im ages will be produced when these sides are m istaken.

As dust and oil adhere easily to the screen, when replacing, always put on gloves (also protects against hazards).

As the lenticular sheet is very thin and tears easily, handle it with extrem e care.

The fresnel lens is such that convex lenses are arranged in flat. Do not expose it to direct sunlight to prevent fire hazards,

burns, and loss of eyesight.

•

When perform ing replacem ents at high places, work very carefully as sm all m istakes m ay lead to serious accidents.

3. PRECAUTIONS FOR ASSEMBLING AND MAINTENANCE

•

Periodically clean the vent nets of the fan of the m ulti-projection unit to prevent it from clogging.

In assem blies and m aintenance, the service person m ust m ove in the cabinet. The following are precautions for this proce-

dure.

•

(1) Do not place load on the screen unit.

(In the procedure, always place weight on the cabinet.

(2) Be careful not to hit your head when m oving the unit.

(3) Do not touch the lens.

(4) AS changing the position of the m ulti-projection unit will change the convergence, do not touch the m ulti-projection unit.

Work carried out at high places is extrem ely hazardous. If tools, etc. are dropped, it will cause not only dam age to the

equipm ent but also injuries to m en as well. Therefore work carefully.

CHAPTER 6. PRECAUTIONS

1. PRECAUTIONS ON FUNCTION AND PERFORMANCE OF SYSTEM

•

The picture m ay turn to disorder tem porarily due to power discharge inside the CRT tube, but it will recover autom atically

after a few seconds. In the new CRT, the very slight am ount of im purities rem aining inside (in vacuum ) m ay occasionally

evaporate when hit with electron beam . However, this will not occur after the CRT has been used for 100 to 200 hours.

•

When the power rem ains off for som e tim e, it m ay indicate that a fault has occurred inside. (m alfunction of parts). Turn off

the m ain power switch of the m ulti-projection unit, and after several seconds, turn it on again.

If the power goes off again, it indicates a fault. If it works norm ally, it indicates abnorm al operations due to external factor

and will not affect operations thereafter.

•

If the screen color and brightness is abnorm al or the switches do not function, turn off the m ain power switch once and turn

it on again several seconds later.

In som e cases, the screen from appear bluish when seen from the left and slightly reddish when seen from the right. This

phenom enon called color shift is inevitable due to the structure of the projection system in which the R G, B tubes are lined

up and light is projected from the rear.

•

When the one im age (still im age and caption) is displayed for a long period of tim e, the im age will stick onto the screen and

cannot be rem oved. As this is inevitable due to the projection system , it m ust be resolved through software contents,

displaying m ethod, system structure, etc.

When bright im ages are displayed in the dark, the light reflected on the lens will shine in the darkness slightly. This phe-

nom enon called tube-inside reflection is inevitable due to the structure of the projection whose CRT light has been ex-

panded using the lens. (Fig. 6-1.)
