1 Safety Precautions
1.1. General Guidelines
· For continued safety, no modification of any circuit must be
attempted.
· Unplug the power cord from the power outlet before
disassembling this projector.
· Use correctly the supplied power cord and must ground it.
· It is advisable to use an isolation transformer in the AC
power line before the service.
· Be careful not to touch the rotation part (cooling fan, etc.) of
this projector when you service with the upper case
removed and the power supply turned ON.
· Observe the original lead dress during the service. If a short
circuit is found, replace all the parts overheated or
damaged by the short circuit.
· After the service, all the protective devices such as
insulation barriers, insulation papers, shields, and isolation
R-C combinations must be properly installed.
· After the service, check the leakage current to prevent the
customer from getting an electric shock.
1.2. Leakage Current Check
1.Prepare the measuring circuit as shown in Fig.1.
Be sure to use a voltmeter having the performance
described in Table 1.
Fig. 1
Table 1
Fig. 2
2.Assemble the circuit as shown in Fig. 2. Plug the power
cord in a power outlet.
3.Connect M1 to T1 according to Fig. 2 and measure the
voltage.
4.Change the connection of M1 from T1 to T2 and measure
the voltage again.
5.The voltmeter must read 0.375 V or lower in both of steps
3 and 4. This means that the current must be 0.75 mA or
less.
6.If the reading is out of the above standard, the projector
must be repaired and rechecked before returning to the
customer because of a possibility of an electric shock.
1.3. UV Precaution and UHM Lamp
Precautions
· Be sure to unplug the power cord from the power outlet
when replacing the lamp.
· Because the lamp reaches a very high temperature during
its operation, wait until it cools completely when replacing
the Lamp Unit.
· The lamp emits small amounts of UV-radiation, avoid direct-
eye contact with the light.
· The lamp unit has high internal pressure. If improperly
handled, explosion might result.

6 Using a Wired Remote Control
6.1. Connection Example
When multiple main units are connected in the system, connect the units with the M3 stereo mini jack cable available in the market
to simultaneously control the multiple main units with a single remote control unit through the REMOTE1 IN/OUT terminal. It is
effective to use the wired remote control in the environment in which an obstacle stands in the light path or where devices are
susceptible to outside light.
6.2. Setting the Projector ID Number for Remote Control
Every projector has its ID number and the ID number of the controlling projector must be set to the remote control in advance so
that the user can operate the remote control. The ID number of the projector is set to “ALL” on shipping, and use the ID ALL button
of the remote control when using only a single projector.
Procedure of ID setting
Press the ID SET button, and within five seconds use the number (0 to 9) buttons to enter the 2-digit ID number set by the
projector.
However, if the ID ALL button is pressed, the projector can be controlled regardless of the ID number of the projector
(simultaneous control mode).

Note:
· Do not press the ID SET button accidentally or carelessly because the ID number on the remote control can be set even
when no projector is around.
If the ID SET button is pressed, the ID number goes back to the one set before pressing the ID SET button unless a
numeric button is pressed within five seconds after the ID SET button is pressed.
· Your specified ID number is stored in the remote control unit unless another one is specified later. However, the stored
ID will be erased if the batteries of the remote control are left exhausted. When the dry cells are replaced, set the same
ID number again.

7.2. Note for Replacement of P.C.Boards
7.2.1. When replacing the A-P.C.Board
· Transfer the data of the original A-P.C.Board to the new A-P.C.Board using the adjustment software and a personal computer.
· If you cannot transfer the data that uses the adjustment software, remove IC2508 and IC2509 from the original board and
mount them on the new board.
* Consult your dealer or Authorized Service Center for the adjustment software.
7.3. Replacement of the lithium battery on the A-P.C.Board
If the lithium battery will be empty, replace it with a new one (CR2032 or equivalent).
Cautions
· Explosion may occur if replacing the battery with an incorrect one.
· Dispose of used batteries according to the instructions.
8 Cautions for Service
Service or repair the product according to service information on the service manual, etc. so that a fire, injury or electric shock
caused by an improper repair may not occur.
1.Do not modify equipments, components and materials when attempting to service or repair.
2.Do not repair nor connect wires even in case of a part of the disconnection when the wiring unit is supplied as a replacement
parts, replace the wiring unit (complete).
3.For a fasten terminal (push-in type terminal), pull out or insert straightly without twisting it.
8.1. Servicing Methods
· Never unplug the power cord from the outlet, open the circuit breaker, or perform other procedures to cut off the power line
during the operation of any cooling fan.
· Be sure to unplug the power cord from the power outlet before servicing.
Powering off the projector
1.Press the POWER STANDBY " " button.
2.Select "OK" with or button and press the ENTER button. (or press the POWER STANDBY " " button again.)
The projection of the image stops, and power indicator of the main unit lights up orange. (The cooling fan keeps running.)
3.Wait until the power indicator of the main unit turns to red (i.e., until the cooling fan stops).
4.Press the " " marked side of the MAIN POWER switch to remove all power from the projector.
8.2. Light Source Lamp
Strong light is emitted from the projector´s lens. Never look into the lens while the projector is being used. If you look directly into
this light, it can hurt and damage your eyes.

10 Replacement of Lamp Unit
10.1. Before replacing the Lamp Unit
WARNING!
· When replacing the lamp, allow it to cool for at least one hour before handling it.
· Make sure that two lamp units are always installed.
10.1.1. Precautions on lamp unit replacement
Remove the power plug and confirm that the surroundings of the lamp unit have cooled off.
· Be careful when handling a light source lamp. The lamp unit has high internal pressure. If improperly handled, explosion might
result.
· A used lamp unit may burst if it is handled violently.
For disposition of used lamps, request an industrial waste disposal contractor.
· If you continue to use a lamp after the replacement time, the lamp may break.
· Philips screwdriver is necessary when replacing a lamp unit.
Take care not to slip your hand when using a screwdriver.
· It is not possible to turn on the power unless two lamp units are installed.
· A lamp unit is an optional part. Contact the dealer.
Replacement lamp unit model No.: ET-LAD57 (single bulb), ET-LAD57W (double bulbs)
· Other lamps than specified above cannot be used. Be sure to use the specified lamp.
10.2. When to replace the Lamp Unit
The lamp units are consumable parts. The lamp brightness decreases gradually as the cumulative operating time increases, so
periodic replacement is necessary. The replacement guideline is 2 000 hours, although the lamp may become dead (will not light)
before 2 000 hours is reached depending on the characteristics of individual lamps and other factors such as the operating
conditions and the installation environment. Therefore, it is recommended for the user to keep a spare lamp unit.
The risk of the lamp bursting increases after 2 000 hours of operation, so the lamp unit turns off automatically.
