Maintenance
Your projector needs little maintenance. All you need to do on a regular basis is keep the lens
clean. You also may need to clean the air filter to prevent overheating.
Warning: Before cleaning any part of the projector, turn it off and unplug the power cord. Never
open any cover on the projector, except as specifically explained in this manual. 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. Do not use sprays that contain
flammable gas to remove dirt and dust from the projector’s lens, air filter, or case.
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.
Note: Carefully open the lens shutter to clean the lens. Do not clean the lens while the projector
is turned on.
■Use a blower brush that is designed for camera equipment to remove dust from the lens.
■To remove dirt or smears, use a lens cloth or tissue. If necessary, moisten the cloth with
lens cleaner and gently wipe the lens surface.
Warning: Do not use a lens cleaner that contains flammable gas. The high heat generated by the
projector lamp may cause a fire.
