Maintenance

Cleaning the Projector

Clean the projector frequently to prevent dust from settling on the surface.
A dirty lens may ruin the quality of the projected image.
Do not use adhesives, lubricants, oils, or alkaline detergents for
maintenance of the projector. They could adhere to the cabinet and
damage it, possibly resulting in the projector falling from its mounting
and causing an accident or personal injury.
Before cleaning the projector, always turn it off, unplug it after the
cooling fan stops, and wait at least one hour. Otherwise, you may get
burned because the main unit is very hot immediately after the
projector is turned off.
Wipe the projector's main unit softly with a soft cloth.
If the projector is heavily soiled, soak the cloth in water with a small amount of
detergent in it, squeeze the cloth thoroughly, and then wipe the projector with it.
After cleaning, wipe the projector with a dry cloth.

Cleaning the Air Filter

The air filter protects the lens and mirror inside the projector from
dust and dirt. Should the air filter become clogged with dust, the
projector may be damaged since it will block the air flow into the
projector and raise the internal temperature of the projector.
The following screen is displayed when turning on the projector if the air filter needs
to be cleaned. Clean the air filter if it is displayed.
• Turn the power of the projector off and pull out the power plug.
• Hook your finger around the air filter handle on the side of the projector and
remove the air filter. Use a vacuum cleaner to clean off the dust.
• Never use volatile cleaning liquid or benzine, as
these may damage the finish of the projector.
• Do not use a chemical dust cloth.
• The lens surface is easily damaged, so do not use
a hard cloth or tissues.
• Only the [ ], [ ], OK and POWER buttons are
available while this screen is displayed. (When you
press the POWER button, the "Push POWER button
again to turn off power." message appears.)
• When this screen has disappeared after being
displayed for 10 seconds, all buttons become operable.
