7. Maintenance This section describes the simple maintenance procedures you should follow to clean the lens, the cabinet, and to replace the lamp. ❶ Cleaning the Lens WARNING • Do not spray flammable gas to get rid of dust and dirt that accumulate in the lens. Doing so could cause a fire. • Turn off the projector before cleaning. • The projector has a plastic lens. Use a commercially available plastic lens cleaner. • Do not scratch or mar the lens surface as a plastic lens is easily scratched. • Never use alcohol or glass lens cleaner as doing so will cause damage to the plastic lens surface. ❷ 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 vents 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 vents. • Clogged vents 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. 131
