Be careful not to damage the claws.

Notes

•The screw is fitted so that it does not come off the filter.

•If the filter is clogged with dirt, etc., the projector goes into an warning state (the OPERATE and STAND BY indicator blink. etc.). Therefore regularly, clean the filter. For the warning indication, refer to page 67.

3Clean the filter.

Clean the filter with a neutral detergent, wash it in water, and then dry it in the shade.

CAUTIONS

• Put on rubber gloves when using neutral detergent.

• After you have washed the filter in water, make sure the filter is completely dry before reinstalling it, otherwise an electri c shock or malfunction could occur.

• Do not clean the filter using a vacuum cleaner. Since the filter is soft, it may be sucked into the vacuum cleaner or damaged.

4Reinstall the filter.

Fasten the screw with a flat-end screwdriver.

Notes
• Install the filter correctly. Otherwise, the projector does not operate. (Goes into an warning state (For the warning indicati	on,
Refer to page 66).)

•If the filter’s claws (in particular the claw which is hidden behind the filter cover knob) are damaged, the projector may not operate. Then, replace with a new filter.
