Cleaning the Lens
Warning: Before you clean any part of the projector, turn off the
projector and unplug the power cord. Never open any cover on the
projector, except the lamp and filter covers. Dangerous electrical
voltages in the projector can injure you severely. Do not try to
service this product yourself, except as specifically explained in this
Product Information Guide. Refer all other servicing to
qualified service personnel.
Clean the lens whenever you notice dirt or dust on the surface.
Lightly wipe the lens surface with a soft, dry, lint-free cloth.
To remove dirt or smears on the lens, moisten a soft cloth
with an alcohol-based cleaner and gently wipe the lens surface.
Cleaning the Projector Case
To clean the projector case, first unplug the power cord. To
remove dirt or dust, wipe the case with a soft, dry, lint-free
cloth. To remove stubborn dirt or stains, moisten a soft cloth
with water and a neutral detergent. Then wipe the case.
Do not use alcohol, benzene, thinner, or other chemical
detergents. These can cause the case to warp.
Cleaning the Air Filter
Clean the air filter at the bottom of the projector after every
100 hours of use. If it is not cleaned periodically, it can
become clogged with dust, preventing proper ventilation. This
can cause overheating and damage the projector.
To clean the air filter, follow these steps:
1. Turn off the projector and unplug the power cable.
2. Turn the projector on its side so that the handle is on top
and you can access the filter easily.
Note: Standing the projector with the handle at the top keeps
dust from getting inside the projector housing.

3. Pull up on the filter cover tab to release the filter cover.
Remove the cover.
4. The filter is attached to the inside of the filter cover. It is
recommended that you use a small vacuum cleaner designed
for computers and other office equipment to clean the filter.
If you don't have one, use a dry, lint-free cloth.
If the dirt is difficult to remove or the filter is torn, replace it.
5. Replace the filter cover when you're done.
Replacing the Lamp
The projection lamp typically lasts for about 2000 hours of
use. It is time to replace the lamp when:
The projected image gets darker or starts to deteriorate.
The projection lamp indicator is either red, or flashing
orange and red alternately.
The message LAMP REPLACE appears on the screen when
the projection lamp comes on (after about 2000 hours). To
maintain the projector brightness and image quality, replace
the lamp as soon as possible.
Warning: Let the lamp cool before replacing it. Also, do not touch
the glass portion of the lamp assembly. Touching the glass portion
of the lamp will result in premature lamp failure.
1. Turn off the projector and unplug the power cable.
2. Turn the projector over so you can access the lamp cover.
