Cleaning the Lens

Warning: Before you clean any part of the projector, turn off the
projector and unplug the power cord. Never open any cover on the
projector, except the lamp and filter covers. Dangerous electrical
voltages in the projector can injure you severely. Do not try to
service this product yourself, except as specifically explained below.
Refer all other servicing to qualified service personnel.
Clean the lens whenever you notice dirt or dust on the surface.
❏ Lightly wipe the lens surface with a soft, dry, lint-free cloth.
❏ To remove dirt or smears on the lens, moisten a soft cloth
with an alcohol-based cleaner and gently wipe the lens
surface.

Cleaning the Projector Case

Before you clean the projector case, turn off the projector and
unplug the power cord.
❏ To remove dirt or dust, wipe the case with a soft, dry, lint-
free cloth.
❏ To remove stubborn dirt or stains, moisten a soft cloth with
water and a neutral detergent. Then wipe the case.
❏ Do not use alcohol, benzene, thinner, or other chemical
detergents. These can cause the case to warp.

Cleaning the Air Filter

Clean the air filter at the bottom of the projector after every
100 hours of use. If it is not cleaned periodically, it can
become clogged with dust, preventing proper ventilation. This
can cause overheating and damage the projector.
Follow these steps:
1. Turn off the projector and unplug the power cable.
2. Turn the projector on its side so that the handle is on top
and you can access the filter easily.
Note: Standing the projector with the handle at the top keeps
dust from getting inside the projector housing.
