caution Do not use glass cleaner to clean the lens. Avoid touching the lens with your bare hands to prevent fingerprints on or damage to the lens surface. Cleaning the Lens Clean the lens whenever you notice dirt or dust on the surface. ■ Use a canister of compressed air to remove dust. ■ To remove dirt or smears on the lens, use lens-cleaning paper. If necessary, moisten a soft cloth with lens cleaner and gently wipe the lens surface. Cleaning the Projector Case Before you clean the case, first turn off the projector 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 mild detergent. Then wipe the case. ■ Do not use wax, alcohol, benzene, paint thinner, or other chemical detergents. These can damage the case. Cleaning and Replacing the Air Filter Your projector includes an air filter to ensure the best performance. If dust collects on the air filter or vent on the side of the projector, clean them as described below. Dust clogs prevent proper ventilation and can cause overheating and damage the projector. When the filter and vent are clogged, the projector displays the message The projector is overheating. Make sure nothing is blocking the air vent, and clean or replace the air filter. 74 Maintenance and Transportation
