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 over heating and damage the projector.
When the projector reached a specified time, the filter warning message “Please clean up filter” appears on the screen, notifying the cleaning is necessary.
To clean the air filter:
1.Switch the projector off and unplug the AC power cord from the wall socket.
2.Place a protective sheet (cloth) beneath the projector. Turn the projector over so you can
see its underside.
Be sure that the projector is stable after turning it over.
3.Remove the air filter by pushing the filter tab.
4.Clean the air filter.
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. Consult your dealer for details. Replacement Filter Part No. : 610 337 9623
5.Replace the filter.
6.Plug the power back into the projector.
7.Be sure to reset the filter counter after cleaning or replacing the filter. See “Filter Counter Reset” on page 30.
Turn off the projector and remove the AC power cord from the power outlet before beginning maintenance work.
Make sure the lens is cool before cleaning.
Do not use detergents or chemicals other than those noted above. Do not use benzene or thinners.
Do not use chemical sprays.
Use a soft cloth or lens paper only.
Be sure to reset the filter counter only after cleaning or replacing the air filter. The filter warning message also appears at turning on.
The filter warning message will not turn off until the filter counter is reset.
Do not operate the projector with the filter removed. Dust may accumulate on the optical elements degrading picture quality.
