Cleaning the Air Filter
The air filter, which is located at the bottom of the projector, should be cleaned after
every 100 hours of use. If it is not cleaned periodically, it can become clogged with
dust and prevent the projector from being ventilated properly. This can cause
overheating and damage the projector.
To clean the air filter:
1. Switch the projector off and unplug the power cable from the wall socket.
2. Turn the projector upside down so that the filter is easily accessible.
3. Note the release latch that retains the filter panel. Slide to release.
Caution:
To clean the filter, you are advised to use a small vacuum cleaner designed
for computers and other office equipment. If the dirt is difficult to remove or
if the filter is torn, replace it. A replacement air filter is provided with
replacement lamps.
4. Replace the filter panel door and plug the power cable back into the projector.
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 LED turns to red (See page 14)
Caution:
The projector lamp develops high heat and high pressure during use. If
the lamp (bulb) ruptures, burns may result. To avoid serious injury, before
attempting to replace the lamp, remove the power cord plug from the outlet
and wait for the lamp (bulb) to cool (wait at least one hour). Then proceed to
replace lamp.
1. Turn off the projector and unplug the power cable.
2. Turn the projector over so you can access the lamp cover.
3. Remove the two access panel screws and open the panel.
4. Grasp the lamp handle and pull the lamp assembly directly out of the projector.
5. Insert the new lamp assembly - making sure not to touch the optical surfaces with
your fingers. Lint-free gloves or finger cots are recommended.
