Lamp replacement (Continued)

Used Lamps

This projector's lamps contain trace amounts of environmentally harmful inorganic

mercury. Be careful not to break used lamps, and dispose of them in accordance with

local regulations.

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.
