7. Maintenance 2 Cleaning the Lens • Turn off the projector before cleaning. • Use a blower or lens paper to clean the lens, and be careful not to scratch or mar the lens. 3 Cleaning the Cabinet Turn off the projector, and unplug the projector before cleaning. • Use a dry soft cloth to wipe dust off the cabinet. If heavily soiled, use a mild detergent. • Never use strong detergents or solvents such as alcohol or thinner. • When cleaning the ventilation slits or the speaker using a vacuum cleaner, do not force the brush of the vacuum cleaner into the slits of the cabinet. Vacuum the dust off the ventilation slits. • Clogged ventilation slits may cause a rise in the internal temperature of the projector, resulting in malfunction. • Do not scratch or hit the cabinet with your fingers or any hard objects • Contact your dealer for cleaning the inside of the projector. NOTE: Do not apply volatile agent such as insecticide on the cabinet, the lens, or the screen. Do not leave a rubber or vinyl product in prolonged contact with it. Otherwise the surface finish will be deteriorated or the coating may be stripped off. 173
