Cleaning the Projector and the Air Filter
Clean the projector frequently to prevent dust from settling on the surface.
A dirty lens may ruin the quality of the projected image.
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 (after approx. 300 hours). 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 front of the projector and
remove the air filter.
When cleaning the projector, make sure to turn off the projector, wait
until the cooling fan stops, disconnect the power plug from the
electrical outlet, and let the projector stand for at least 1 hour.
Otherwise, you may get burned because the main unit is very hot
immediately after the projector is turned off.
• Never use volatile cleaning liquid or benzine, as these may damage the finish of the
projector.
• When using a chemical dust cloth, make sure to read the instructions thoroughly.
• When cleaning the projector’s lens, use a commonly available air blower or lens
cleaning paper. 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.
