Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface.
To remove dirt or smears on the lens, use a commercially available
cloth for cleaning glasses.
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
Your projector includes an air filter to ensure the best performance. If
dust collects on the air filter or vent on the bottom of the projector,
clean them as described below. Dust clogs prevent proper ventilation
and can cause overheating and damage the projector.
When the filter and vent 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.
caution
Do not use glass cleaner to
clean the lens.
