Lens and main unit cleaning

WARNING

•Request cleaning and maintenance of a ceiling-mounted unit from your projector dealership. Attempting to clean or replace the lamp in a high location by yourself may cause you to fall, resulting in injury.

N 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.

N Main unit cleaning

•Unplug the power cord before cleaning the main unit.

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

electric shock or unit failure.
