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. 95
