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 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.
• 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.
