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. If the air-filter or ventilation
grille become clogged with dirt or dust, the temperature
inside the projector may rise and the power is shut off . (The
TEMP indicator starts to blink red).
For side air outlet grille
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
air-filter. Rinse the air-filter
thoroughly and let it dry
completely.
4. Attach the air-filter to the cover.
5. Reinstall the filter cover.
Important:
• If the air-filter is damaged or becomes extremely dirty,
contact your dealer for replacement.
Caution:
Be sure to use the projector with an air-filter attached. 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 ventilation
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 surface is
fragile. Use only recommended, nonabrasive lens-cleaning
materials. Do not touch the lens with your fingers.

the OPTICAL UNIT with the MAIN PCB ASSY removed.
(Use it mainly when removing dust from the LCD panel.)
Also use it to check each power system when the self-
diagnosis function finds any error such as a power error.
