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.

Replacing cooling fans

To maintain the performance, it is recommended that cooling fans should be replaced
about every 2 to 3 years. Consult with your dealer for details.
