Maintenance Your projector needs little maintenance. Things you have to do on a regular basis are keep the lens clean. Never remove any parts of the projector except the lamp. Contact your dealer if other parts needs replacing. Cleaning the Lens Clean the lens whenever you notice dirt or dust on the surface. Use a canister of compressed air to remove dust. If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner to gently wipe the lens surface. Never rub the lens with abrasive materials. Cleaning the Projector Case Before you clean the case, turn the projector off and unplug the power cord. To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth. To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral detergent. Then wipe the case. Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case. Storing the Projector If you need to store the projector for an extended time, please follow the instructions below.
