Maintenance
Cleaning of the projector and the
ventilation slots
Use a soft cloth to clean the projector and the ventila-
tion grilles. When the grilles become dirty, wipe them
with a soft cloth dampened with diluted mild deter-
gent, 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 projector.
Cleaning of 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.
Warning:
• Never use flammable air duster or other
materials when cleaning the air-filter. Flammable
substances may ignite causing fire or breakdown
when the lamp is illuminated.
• Do not use flammable solvents (benzene, thinner,
etc.) and flammable aerosols when cleaning the
projector body and lens. Flammable substances
may ignite causing fire or breakdown while the
lamp is illuminating.
Caution:
Be sure to turn off the lamp and unplug the power
cord from the wall outlet before you perform any
maintenance on the projector.
Cleaning of the air-filter
Clean the air-filter fre-
quently (about once a
month). If the filter or
ventilation grilles become
clogged with dirt or dust,
the temperature inside
the projector may rise and
cause troubles, such as
damage to the inside
parts and shortening the
life of the panels.
• When the temperature
inside the projector rises, the STATUS indicator
will blink orange and the lamp will be turned off.
1. Put the projector upside
down and raise the lock of
the filter cover in the
direction of the arrow.
2. Remove the air-filter.
3. Wash the air-filter or
change it with a new filter.
• Use water or diluted
mild detergent to clean
the filter. Rinse the filter
thoroughly and let it dry
completely.
4. Attach the air-filter.
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 it with a new filter. Contact your
dealer for a new filter.
• The projector will not turn on if the air-filter cover
is attached improperly .
Caution:
Be sure to use the projector with an air-filter. If not,
dust may get inside the projector causing fire and
failure.
