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.
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.
