Maintenance General Precautions
• Make sure the projector is turned off 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 scuffed, 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 still not clean, use lens-cleaning paper or moisten a soft cloth with
lens cleaner and gently wipe the surface.
CAUTION: Never rub the lens with abrasive materials.
Cleaning the Case
• Use a soft, lint-free, dry cloth to remove dirt or dust.
• If the case is still not clean, apply a small amount of non-ammonia, non-alcohol
based, mild non-abrasive detergent onto a clean, soft, lint-free cloth, then wipe
the surface.
CAUTION: Never use wax, alcohol, benzene, thinner, or other chemical detergents.
Storing the Projector
If you intend to store the projector for an extended period of time:
• Ensure the temperature and humidity of the storage area are within the
recommend range.
• Retract the adjuster foot completely.
• Remove the batteries from the remote control.
• Pack the projector in its original packaging or equivalent.
Disclaimer
• ViewSonic® does not recommend the use of any ammonia or alcohol-based
cleaners on the lens or case. Some chemical cleaners have been reported to
damage the lens and/or case of the projector.
• ViewSonic® will not be liable for damage resulting from use of any ammonia or
alcohol-based cleaners.
