1. COMPLIANCE OF SAFE REPAIR
Be sure to read this Service Manual before providing services. In the projector, full
consideration is taken to ensure safety for fire, electric shock, injury, harmful radiation, and
substance. Therefore, observe the notice described in this Service Manual so that safety is
kept when providing services. Moreover, be sure to observe the notice described in the
Instruction Manual.
Pay attention to the following items during service inspection.
1.1 Cautions during disassembling and assembling
1. This equipment contains parts under high voltage. When making repairs, etc.
Be sure to pull out the power plug beforehand to insure safety.
2. Parts may be very hot immediately after use.
Make sure the equipment has cooled off sufficiently before carrying out repairs.
3. Make sure that parts and screws and wiring, etc. are returned to their original positions.
Tube, tape and other insulation materials have been used for safety reasons.
The internal wiring has been designed to avoid direct contact with hot parts or parts under
high voltage when using clamps or other tools.
4. The parts used in this device have special safety features such as flame-resistance and
anti-voltage properties. When replacing parts, always use parts supplied from the factory.
5. After finishing operations make sure that all parts and wires have been returned to their
original position and that there has been no deterioration of the area around the location that
was worked on.
6. Be sure to use a grounding strap (wrist band) during repair and inspection.
1.2 Lamp
During current conduction, the lamp is in the high-temperature state. In this case, pay
careful attention because a high voltage is used. When replacing a lamp, replace it after
confirming that the lamp has gotten cold sufficiently.
1.3 Lens
Do not look into a lens during projection. This damages your eyes.

2-7. Remote Control Parts
Important:
1. Avoid using the projector with bright fluorescent lighting turned on. Certain high-frequency
fluorescent lights can disrupt remote control operation.
2. Be sure nothing obstructs the path between the remote control and the projector. If the path
between the remote control and the projector is obstructed, you can bounce the signal off
certain reflective surfaces such as projector screens.
3. The buttons and keys on the projector have the same functions as the corresponding
buttons on the remote control. This user’s manual describes the functions based on the remote
control.
