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.
