Appendix A. Maintenance

This chapter describes how to clean the lens, replace the projection lamp, and use
the security lock.

Cleaning the lens

To clean the lens:
1.

Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
Avoid using an excessive amount of cleaner. Do not apply the cleaner directly
to the lens. Abrasive cleaners, solvents, or other harsh chemicals might scratch
the lens.

2.

Lightly wipe the cleaning cloth over the lens in a circular motion. If you do not
intend to use the projector immediately, replace the lens cap.

Replacing the projection lamp

The lamp hour timer in the About menu counts the number of hours the lamp has
been in use. After

1,980 hours, the message “Change lamp” briefly appears on the

screen at each startup. When the timer reaches

2,000 hours, the lamp will no longer

light. You can order new lamp modules from your dealer.

To change the projection lamp:

1.

Turn off the projector and unplug the power cable.

2.

Wait 60 minutes to allow the projector to cool thoroughly.

3.

Turn the projector upside down and remove the lamp door by removing the
two screws and sliding the lamp door tabs out of the three tab bays.
CAUTION:
Never operate the projector with the lamp door removed. This disrupts the
air flow and causes the projector to overheat.

4.

Loosen the captive screw on the lamp module.
CAUTION:

v

This product contains a Metal Arc lamp which contains Mercury. Dispose
of as required by local ordinances and regulations.

v

To avoid burns, allow the projector to cool for at least 60 minutes before
you replace the lamp.

v

Do not drop the lamp module. The glass may shatter and cause injury.

v

Do not touch the glass lamp screen. Fingerprints can obscure projection
sharpness.

v

Be extremely careful when removing the lamp housing. In the unlikely
event that the lamp ruptures, small glass fragments may be generated.
The lamp module is designed to contain most of these fragments, but use
caution when removing it.

5.

Carefully remove the lamp module by grasping and lifting the metal bail wire.
Dispose of the lamp in an environmentally proper manner.

6.

Install the new lamp module, making sure that it is properly seated.

7.

Tighten the single screw.
