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,
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.

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.
