Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface.

•Use a canister of compressed air to remove dust.

•If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently wipe the lens surface.

Never rub the lens with abrasive materials.

Cleaning the projector case

Before you clean the case, turn the projector off using the proper shutdown procedure as described in "Shutting down the projector" on page 38 and unplug the power cord.

•To remove dirt or dust, wipe the case with a soft, lint-free cloth.
