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.
• If the soiling is severe, dip the cloth in a neutral
detergent diluted in water, wring well, and gently wipe
off the dirt, then finish up by wiping with a dry cloth.
