83 5 Maintaining the Projector Your projector needs little maintenance. All you have to do on a regular basis is clean the lens, and check that the air filter and vents are clean. A clogged air filter or vent can block ventilation needed to cool the projector. The only parts you should replace are the lamp and air filter. If any other part needs replacing, contact your dealer or a qualified servicer. This chapter covers the following: ■Cleaning the lens ■Cleaning the projector case ■Cleaning the air filter ■Replacing the air filter ■Replacing the lamp ■Replacing the remote control batteries ■Transporting the projector warning Before you clean any part of the projector, turn it off and unplug the power cord. Never open any cover on the projector, except the lamp cover. Dangerous electrical voltages in the projector can injure you severely. Do not try to service this product yourself, except as specifically explained in this User’s Guide. Refer all other servicing to qualified service personnel.
84Maintaining the Projector Cleaning the Lens Clean the lens whenever you notice dirt or dust on the surface. To remove dirt or smears on the lens, use a commercially available cloth for cleaning glasses. Cleaning the Projector Case Before cleaning, 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 neutral detergent and firmly wring the cloth dry. Then wipe the case. Cleaning the Air Filter Your projector includes an air filter to ensure the best performance. If dust collects on the air filter, clean it as described here. Dust clogs prevent proper ventilation and can cause overheating, which can damage the projector. 1. Turn off the projector and unplug the power cord. 2. Remove dust from the air filter using a small vacuum cleaner designed for computer or office equipment, or gently clean the vent with a soft brush (such as an artist’s paintbrush). caution Do not rub the lens with harsh materials or subject the lens to shocks, or you may damage it. Do not use wax, alcohol, benzene, paint thinner, or other chemical detergents. These can damage the case. note To order replacement air filters, request part number V13H134A25. See page 18 for ordering information.
