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.

• When cleaning the ventilation slits or the speaker using a vacuum cleaner, do not force the brush of the vacuum
cleaner into the slits of the cabinet.

• 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
