Maintenance
The projector needs proper maintenance. You should keep the lens clean as dust, dirt
or spots will project on the screen and diminish image quality. The only part you could
replace yourself is the lamp. If any other parts need replacing, contact your dealer or
qualified service personnel. When cleaning any part of the projector, always switch off
and unplug the projector first.
Warning:
Never open any of the covers on the projector except the lamp cover. Dangerous
electrical voltages inside the projector can cause severe injury. Except as specifically
indicated in this User’s Manual, do not attempt to service this product yourself.
Refer all servicing to qualified service personnel.
Cleaning the Lens
Gently wipe the lens with lens cleaning paper. Do not touch the lens with your hands.
Cleaning the Projector Housing
Gently wipe with a soft cloth. If dirt and stains are not easily removed, use a soft cloth
damped with water, or water and neutral detergent, and wipe dry with a soft, dry cloth.
Turn off the projector and remove the AC power cord from the power
outlet before beginning maintenance work.
Make sure the lens is cool before cleaning.
Do not use detergents or chemicals other than those noted above. Do
not use benzene or thinners.
Do not use chemical sprays.
Use a soft cloth or lens paper only.
