Maintenance

Warning:

•Do not use flammable solvents (benzene, thinner, etc.) and flammable aerosols when cleaning the projector body

and lens. Flammable substances may ignite causing fire or breakdown while the lamp is illuminating.

Caution:

•Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance on the projector.

Cleaning of the projector and the ventilation slots

Use a soft cloth to clean the projector and the ventilation grilles. When the grilles become dirty, wipe them with a soft cloth dampened with diluted mild detergent, and then wipe them with a dry cloth.

•Clean the inside of the terminal cover frequently as dust is apt to be collected.

To protect the surface of the projector from fading or deteriorating:

•Do not spray insecticide on or inside the projector.

•Do not use benzine or thinner to clean it.

•Do not let rubber or plastic materials contact with projector.

Cleaning of the lens

Use a standard lens-cleaning brush or a piece of lens tissue dampened with lens cleaning fluid. The lens surface is fragile. Use only recommended, nonabrasive lens-cleaning materials. Do not touch the lens with your fingers.
