Other care
■
Before caring, make sure the power cable is not plugged in, and then allow the projector to cool
sufficiently. The care in a high temperature state of the projector could cause a burn and/or
malfunction to the projector.
Avoid wetting the projector or inserting liquids in the projector. It could result in a fire, an electric
shock, and/or malfunction to the projector.
• Don't put a container containing water, cleaner or chemicals near the projector.
• Don't use aerosols or sprays.
Please take right care of the projector according to the following. Incorrect care could cause not
only an injury but adverse influence such as discoloration, peeling paint, etc.
• Do not use cleaner or chemicals other than those listed below.
• Do not polish or wipe with hard objects.
 Inside of the projector
In order to ensure the safe use of the projector, it needs to clean and inspect the projector about
once a year.
 Caring for the lens
If the lens is flawed, soiled or fogged, it could cause deterioration of display quality. Please take
care of the lens, being cautions of the handling.
1. Turn the projector off, and unplug the power cord. Allow the projector to cool sufficiently.
2. After making sure that the projector is cool adequately, lightly wipe the lens with a commercially
available lens-cleaning wipe. Do not touch the lens directly with your hand.
• Use commercially available lens tissue to clean the lens (used to clean cameras, eyeglasses, etc.).
• If the lens is heavily soiled, wipe it with a cloth moistened with little water.
• Never use polishing agents, detergents, chemicals, or solvents such as benzine or thinner.
• Excepting for lens, use a soft cloth to clean. When excessively soiled, dilute a neutral detergent in
water, wet and wring out the soft cloth.
 Caring for the cabinet and remote control
Incorrect care could have adverse influence such as discoloration, peeling paint, etc.
1. Turn the projector off, and unplug the power cord. Allow the projector to cool sufficiently.
2. After making sure that the projector is cool adequately, lightly wipe with gauze or a soft cloth. If
soiling is severe, dip soft cloth in water or a neutral cleaner dilute in water, and wipe lightly after
wringing well. Then, wipe lightly with a soft, dry cloth.
