Maintenance - Mitsubishi Electric DLP HC7900DW User Manual

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.
• Ask your dealer for annual cleaning of the inside of the projector. If you continue to use the projector with dust
inside, it may result in fire or malfunction.
Cleaning of the projector and the vents
Use a soft cloth to clean the projector and the vents. When the vents become dirty, wipe them with a soft cloth
dampened with diluted mild detergent, and then wipe them with a dry cloth.
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.
