Maintenance
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. 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. Use a vacuum cleaner to clean off the dust.
• If the air filter cleaning screen is displayed when turning on the projector after
cleaning the air filter, select [Yes] and press the OK button.
The air filter counter is
reset, and the message is no longer displayed.
• This screen is not displayed when [Air filter warning display] is set to [Off]. (P91)
Reset the air filter counter manually. (P102)
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.
• 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.
