6. Maintenance WARNING • Turn off the projector, and unplug the projector before cleaning. • Please do not use a spray containing flammable gas to remove dust attached to the lens or the cabinet, etc. Doing so may result in fires. 6-1. Cleaning the Lens • Use a blower or lens paper to clean the lens, and be careful not to scratch or mar the lens. 6-2. Cleaning the Cabinet • 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 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. • Poor ventilation caused by dust accumulation in ventilation openings can result in overheating and malfunction. These areas should be cleaned regularly. • 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. 73
