•Request cleaning and maintenance of a ceiling-mounted unit from your projector dealership. Attempting to clean/replace the lamp at a high site by yourself may cause you to drop down, thus resulting in injury.

■ Lens cleaning

• Clean the lens with a commercially available blower and/or lens cleaner.

• The lens is easily scratched, so do not rub it with hard objects, or strike it.

■Main unit cleaning

•Clean the main unit after unplugging the power cord.

• Wipe dirt off the main unit gently with a soft cloth.

• Do not wipe the main unit with a damp cloth. Doing so may allow water to get inside, resulting in an electric shock or failure.
