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. 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. Dangerous electrical voltages inside the

projector can cause severe injury. 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.

Note

• 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.
