9. Maintenance
❷ Cleaning the Lens
• 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.
WARNING
• Please do not use a spray containing flammable gas to remove dust attached to the lens, etc. Doing so may
result in fires.
❸ 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 pro-
longed contact with it. Otherwise the surface finish will be deteriorated or the coating may be stripped off.
