If your projector is ceiling-mounted or is not easily accessible, pay special attention to 
your personal safety when replacing the dust filter.
Installing the dust filter
1.
Be sure to turn off the projector and unplug it 
from power source.
2.
As the arrows shown to the right, fit the filter 
by aligning and inserting it into the projector 
slots. Make sure it clicks into place.
For first time installation:
3.
Open the OSD menu and go to the SYSTEM SETTING: ADVANCED > Filter 
Settings menu.
4.
Press Enter and the Filter Settings page is displayed.
5.
Highlight Filter Mode and press 
/  to select On. The filter timer starts counting.
Set Filter Mode to On only when using the projector after the dust filer (optional accessory) is 
properly attached. Failing to do so will result in a shorter lamp life.
Obtaining the filter hour information
1.
Open the OSD menu and go to the SYSTEM SETTING: ADVANCED > 
Filter Settings menu.
2.
Press Enter. The Filter Settings page is displayed.
3.
Cleaning the dust filter
1.
Be sure to turn off the projector and unplug it from power source.
2.
Press the latches on the dust filter and remove the filter from the projector. 
3.
Use a small vacuum cleaner or a soft brush to sweep the dust on the filter away.
4.
Re-install the dust filter.
Resetting the filter timer
5.
Open the OSD menu and go to the SYSTEM SETTING: ADVANCED > 
Filter Settings menu.
6.
Press Enter and the Filter Settings page is displayed.
7.
Highlight Reset Filter Hours and press Enter. A warning message is displayed 
asking if you want to reset the filter timer. 
8.
Highlight Reset and press Enter. The lamp time will be reset to '0'.
CAUTION
Remember to set Filter Mode to Off in the SYSTEM SETTING: ADVANCED > Filter Settings 
menu when using the projector with the dust filter removed. Setting Filter Mode to Off does 
not reset the filter timer. The timer will continue counting the next time you fit the filter back on 
and set Filter Mode to On.
