Maintenance
Your projector needs little maintenance. All you need to do on a regular basis is keep the lens
clean. You also need to clean the air filter periodically to prevent overheating.
Warning: Before you clean any part of the projector, turn it off and unplug the power cord. Never
open any cover on the projector, except the lamp and filter covers. Dangerous electrical voltages
in the projector can injure you severely. Do not try to service this product yourself, except as
specifically explained in this User’s Guide.
The only parts you should replace are the air filter and the lamp. If another part needs
replacing, contact your dealer or a qualified servicer.
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, use lens-cleaning paper. If
necessary, moisten a soft cloth with lens cleaner and
gently wipe the lens surface.
Caution: Never rub the lens with abrasive materials.
