8-1. Cleaning the Lens

• 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
• Do not use a spray containing flammable gas to remove dust attached to the lens, etc. Doing
so may result in fire.
• Turn off the power, unplug the power plug from the socket and remove the lens for cleaning.
If the unit turns on while cleaning the lens, the strong light from the lens could damage your
eyes. It could also burn your fingers.
