Maintenance
Caution:
Be sure to turn off the projector and unplug the
power cord from the wall outlet before you perform
any maintenance 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
inside 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.
1. To remove the filter
cover, slide the cover
in the direction of the
arrow.
2. Remove the air-
filter from the filter
cover.
3. Wash the air-filter or
change to the new filter.
• Use water or a mild
detergent diluted with
water to clean the filter.
Rinse the filter thor-
oughly and let it dry
completely.
4. Attach the air-filter to the filter cover.
5. Attach the filter cover to the projector.
• Make sure that the air-filter is attached cor-
rectly without displacement.
Important:
• If the filter is damaged or becomes extremely
dirty, change to the provided new filter. If you
wish to another new filter, 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.
• Clean the inside of the terminal cover frequently
as dust is apt to be collected.
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
surface is fragile. Use only recommended, nonabra-
sive lens-cleaning materials. Do not touch the lens
with your fingers.
