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.

- It is advisable to use an isolation transformer in the AC power line

before the service.

- 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

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.

- Because the high pressure lamp involves a risk of explosion, never

touch the lamp wire lead during the service. (See Fig. 3)

or higher above sea level.

- Not to use the projector at highlands exceeding 2 700 meters above sea

level.

- AUTOSETUP

Setting AUTO SETUP mode

- NORMAL: To set the normal mode (the dot clock is adjusted strictly)

- SPECIAL: To set the special mode (the dot clock is adjusted roughly)

* Do not change the initial setting (NORMAL).

White (No pattern)] in the four colors (White, Red, Green and Blue).

Note:

- On the service mode, displays above patterns by each color without

test equipment such as PC or SG. Use the service mode for simplified

adjustments by your eyes and so on.

4.1. Procedure to enter the service mode

Select "SERVICE MODE" on "EXT OPTION" menu and press "ENTER" button on the remote control

unit.

Note:

Caution:

- While turning over a printed circuit board, be sure to put a insulating

material under it to prevent a short circuit.

- Printed circuit boards and wires must not be pulled forcibly, but be

handled carefully.

- Connectors also must be handled carefully.

- After repairing this projector, be sure to put back the wires and

connectors to the original condition.
