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. Insert the tabs,
then press down.
Replacing the Lamp
The projector 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 projector lamp comes on.
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.
