Maintenance
Caution:
Be sure to turn off the projector and unplug the power
cord from the wall outlet before you perform any main-
tenance on the projector.
Cleaning the air-filter
Clean the air-filter frequently. If the filter or ventilation
grille 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).
1. To remove the filter cover, press the
ridged area gently, push the cover in the
direction of the arrow and lift.
2. Remove the air-filter from the filter
cover.
3. Wash the air-filter.
• Use water or a mild
detergent diluted with
water to clean the filter.
Rinse the filter
thoroughly and let it dry
completely.
4. Attach the filter to the cover.
5. Reinstall the filter cover.
Important:
• If the filter is damaged or becomes extremely
dirty, contact your dealer for replacement.
Caution:
Be sure to use the projector with an air-filter. If not,
dust may get inside the projector, causing a fire or a
breakdown.
Cleaning the projector and the ventilation
grille
Use a soft cloth to clean the projector and the ventila-
tion grille. When the grille 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 fin-
gers.
