Lens and main unit cleaning

WARNING

•

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 fall

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.

• Do not use benzene, thinner and the like as they may

deform or discolor the unit or damage the paint

surface.

• When using a chemically treated cloth, follow the

precautions included with the cloth.
