Cleaning the Lens Cover Glass
Clean the lens cover glass whenever you notice dirt or dust on the
surface.
■ Use a canister of compressed air to remove dust.
■ To remove dirt or smears on the lens cover glass, use lens-cleaning
paper. If necessary, moisten a soft cloth with lens cleaner and
gently wipe the glass surface.
Cleaning the Projector Case
Before you clean the case, first 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 mild detergent. Then wipe the case.
■ Do not use wax, alcohol, benzene, paint thinner, or other
chemical detergents. These can damage the case.
Cleaning and Replacing the Air Filter
Clean the air filter and the air vents on the sides of the projector
periodically or whenever you see a message telling you to clean them.
If they are not cleaned periodically, they can become clogged with
dust, preventing proper ventilation. This can cause overheating and
damage the projector.
When the filter and vents are clogged, the projector displays the
message
The projector is overheating. Make sure nothing is
blocking the air vent, and clean or replace the air filter
.
When it’s time to replace the air filter, the projector displays the
message
Time to clean the air filter. Clean or replace the air filter.
caution
Do not use glass cleaner to
clean the lens cover glass.
note
You can check to see how
many hours since the air filter
was last cleaned or replaced.
