Dust lter maintenance
Dust lter replacement
The dust lter can be used to prevent the dust from piling up on the surface of the optical element in
the projector. If the dust lter is dirty or blocked, the projector would heat excessively or the quality of
projected image would be reduced.
1. A replacement notice pops up after the dust lter is used for 500 hours. Select Reset to reset the
timer and replace the dust lter.
2. A reminder pops up when you reboot the projector next time if you select Cancel until you select
Reset.

It is suggested that you should use a ladder when replacing the dust lter. Do not remove the projector from the wall mount
bracket.
