r
Do not tilt the projector or place it on its side.
Do not tilt the projector body more than approximately ±40° vertically or ±15° horizontally. Over tilting may result in
shortening the life of the components.
The angle that can be corrected through [POSITION] menu → [SCREEN ADJUSTMENT] → [KEYSTONE] is within
±35°. If the vertical tilt of the projector with respect to the screen surface exceeds 35°, vertical trapezoidal distortion
may not be fully corrected.
r
Cautions when setting up the projectors
f
Use the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other
purposes may damage the projector.
f
Do not stack the projectors.
f
Do not use the projector supporting it by the top.
f
Do not block the ventilation ports (intake and exhaust) of the projector.
f
Avoid heating and cooling air from the air conditioning system directly blow to the ventilation ports (intake and
exhaust) of the projector.

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 parts (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 for 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.
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 0.75mA 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 be resulted.
- Because the high pressure lamp involves a risk of failure, never touch the lamp wire lead during the service.
