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
3

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.
- Because the high pressure lamp involves a risk of explosion, never
touch the lamp wire lead during the service. (See Fig. 3)

5. Disassembly Instructions
Warning:
- Be sure to unplug the power cord from the power outlet before
disassembling this projector.
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.
