CAUTION
If you use the projector mounted on the
ceiling, ask the dealer to carry out the
maintenance such as cleaning.
Cleaning the air filter
The filter under the air filter cover is the device
to shut out dusts or dregs.
Do not use the projector with the filter taken off.
Give a frequent clean especially to the air filter.
(The cleaning period is once per about 50
hours).
1) Unplug the power cord.
2) Take off the air filter cover.
The filter is on the right side of the projector.
Pull up the filter tabs.
3) Clean the air filter cover.
Remove dust and stains with a vacuum
cleaner.

4) Attach the air filter cover.
Notes
• When the air filter is dusty, the ventilation is
impaired. This causes the temperature inside
the projector to rise, and may damage the
unit.
• Attach the air filter cover firmly after the
cleaning. If it is not set correctly, the dusts will
enter and they will be projected and
overlapped on the picture.
Cleaning the lens
Use a blower or a lens cleaner to clean the
lens.
Never rub or tap the lens with a hard object as
the lens surface is fragile.
Cleaning the main unit
• Pull out the power cord before cleaning.
• Use a soft cloth to wipe off stains from the
surface.
• To remove difficult stains, use a soft cloth
slightly moistened with a weak solution of
synthetic detergent and water, and finish with
a soft, dry cloth.
Replacing the intake, exhaust fans
and air filter
To maintain the efficiency of the projector,
replace the intake and exhaust fans about
every two to three years.
Ask the dealer for the replacement.
