	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.

Remote Control Operating Range

The remote control uses infrared transmission to control the projector. It is not necessary to point the remote directly at the projector. Provided you are not holding the remote perpendicular to the sides or the rear of the projector, the remote will function well within a radius of about 7 meters (23 feet) and 15 degrees above or below the projector level. If the projector does not respond to the remote control, move a little closer.

Common problems and solutions

These guidelines provide tips to deal with problems you may encounter while using the projector. If the problem remains unsolved, contact your dealer for assistance.

Often after time spent troubleshooting, the problem is traced to something as simple as a loose connection. Check the following before proceeding to the problem-specific solutions.

•Use some other electrical device to confirm that the electrical outlet is working.

•Ensure the projector is turned on.

•Ensure all connections are securely attached.

•Ensure the attached device is turned on.

•Ensure a connected PC is not in suspending mode.

Ensure a connected notebook computer is configured for an external display. (This is usually done by pressing an Fn-key combination on the notebook.)

Image Problems

Problem: No image appears on the screen

1.Verify the settings on your notebook or desktop PC.

2.Turn off all equipment and power up again in the correct order.

Problem: The image is blurred

1.Adjust the Focus on the projector.

2.Press the Auto button on the remote control or projector.

3.Ensure the projector-to-screen distance is within the 10-meter (33-feet) specified range.

4.Check that the projector lens is clean.
