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.
• 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.
Vacuum the dust off the vents.
