caution

Do not use glass cleaner to clean the lens.

Cleaning the Lens

Clean the lens 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, use lens-cleaning paper. If necessary, moisten a soft cloth with lens cleaner and gently wipe the lens 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 air intake and exhaust vent on the bottom of the projector after every 100 hours of use. 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 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.
