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 (at least once a
month). If the filter or ventilation slots become
clogged with dirt and dust, the temperature inside
the projector may rise to cause troubles, such as
damage to the inside parts, and shorten the life of
the panel.
• Even if the air-filter is cleaned periodically, it will
deteriorate in its performance with time. Replace
the air filter with a new one once a year. Consult
your dealer about purchase of a new air-filter.
• When the temperature inside the projector rises,
the STATUS indicator will blink red and the
power will be shut off to be on standby with the
LAMP indicator turned
off.
1. Remove the screw (a) of
the front grille using a
Phillips screwdriver.
• Be careful not to lose the
removed screw.
2. Pull the front grille in the
direction of the arrow. Release
the two hooks and remove the
front grille.
• Do not pull the front grille forcibly when releasing
the two hooks from the projector.
3. Remove the air-filter from
the front grille.
4. Clean dirt and dust on the
air-filter using a vacuum,
or replace the air-filter with a new one.
• Use water or a mild detergent diluted with
water to clean stubborn dirt from the air-filter.
Rinse the air-filter thoroughly and let it dry
completely.
5. Attach the air-filter to the front grille.
• Attach the air-filter so that it is retained by the
seven protrusions inside the front grille. Then
spread the air-filter on the front grille by
pressing it. (Make sure that the air-filter is
caught by the protrusions, which prevent it
from being displaced.)
6. Attach the front grille to the projector.
• Make sure that the air-filter is attached
correctly without being displaced.
7. Tighten up the screw (a) using a Phillips
screwdriver.

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.
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.
