Dust filter maintenance
Dust filter replacement
The dust filter can be used to prevent the dust from piling up on the surface of the optical element in
the projector. If the dust filter 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 filter is used for 500 hours. Select Reset to reset the
timer and replace the dust filter.
2. A reminder pops up when you reboot the projector next time if you select Cancel until you select
Reset.

Caution:
It is suggested that you should avoid using the projector in a dusty or smoky environment, otherwise the picture quality might
be reduced. If the dust filter is seriously blocked and cannot be cleaned, replace it with a new one.
Note:
It is suggested that you should use a ladder when replacing the dust filter. Do not remove the projector from the wall mount
bracket.
