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 (about once a month). If
the filter or ventilation slots become clogged with dirt
or dust, the temperature inside of the projector may
rise and cause some troubles, such as damage of in-
side parts, and shortening the life of panel.
• When the temperature inside of the projector
rises, the TEMP indicator blinks in red, and the
power will be shut off to be stand-by which LAMP
indicator is turned off.
Filter cover
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.
• The power will not turn on if the air-filter cover is
improperly installed.
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
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.
