Cleaning the air-filter

This projector has two air-filters, for bottom air-outlet slots and for front air outlet slots. Clean the air-filter frequently. If the filter or ventilation slots become clogged with dirt or dust, the temperature inside the projector may rise and shut off the power (the TEMP indicator starts to blink red).

Cleaning the projector and the ventilation slots

Use a soft cloth to clean the projector and the ventila- tion slots. When the slots become dirty, wipe them with a soft cloth dampened with a diluted mild detergent, and then wipe them with a dry cloth.

To protect the surface of the projector from fading or deteriorating:

•Do not spray insecticide on or inside the projector.

•Do not use benzine or thinner to clean it.

•Do not let rubber or plastic materials come into contact with the projector.

Cleaning the lens

Use a standard lens-cleaning brush or a piece of lens tissue dampened with lens cleaning fluid. The lens sur- face is fragile. Use only recommended, nonabrasive lens-cleaning materials. Do not touch the lens with your fingers.

Important:

•If the filter is damaged or becomes extremely dirty, contact your dealer for replacement.

•The power will not turn on if the air-filter cover is improperly installed.
