Maintenance
General Precautions
• Make sure the Projector is turned o and the power cable is unplugged from the
power outlet.
• Never remove any parts from the Projector. Contact ViewSonic® or a reseller
when any part of the Projector needs replacing.
• Never spray or pour any liquid directly onto the case.
• Handle the Projector with care, as a darker-colored projector, if scued, may
show marks more clearly than a lighter-colored projector.
Cleaning the Lens
• Use a canister of compressed air to remove dust.
• If the lens is sll not clean, use lens-cleaning paper or moisten a so cloth with
lens cleaner and gently wipe the surface.
CAUTION: Never rub the lens with abrasive materials.
Cleaning the Case
• Use a so, lint-free, dry cloth to remove dirt or dust.
• If the case is sll not clean, apply a small amount of non-ammonia, non-alcohol
based, mild non-abrasive detergent onto a clean, so, lint-free cloth, then wipe
the surface.
CAUTION: Never use wax, alcohol, benzene, thinner, or other chemical detergents.
