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 tissue. 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 neutral detergent. Then wipe the case.
■ Do not use wax, alcohol, benzene, thinner, or other chemical
detergents. These can damage the case.
