Maintenance

Replacing the Filter Cartridge

Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes clogged
with dust particles, it will reduce cooling fans' effectiveness and may result in internal heat buildup and adversely af-
fect the life of the projector. This projector has an electrically operated filter which helps you to replace the filter easily.
The projector monitors the condition of the filter at all time and replaces a filter with a new one automatically when it
detects the clogging.
If the projector detects that the filter is clogged and no scroll is left in the filter cartridge, a Filter cartridge replacement
icon appears on the screen and the WARNING FILTER indicator on the top panel lights up. When you see this icon,
replace the filter cartridge and reset the Filter counter and the Scroll counter.

CAUTION
Make sure the filter cartridge is inserted in the

cover is closed when using the projector.
Do not put anything into the air vents. Doing so may
result in malfunction of the projector.
RECOMMENDATION
We recommend avoiding dusty/smoky environments
when operating the projector. Usage in these environ-
ments may cause a poor image quality.
When using the projector under dusty or smoky conditions,
dust may accumulate on a lens, liquid crystal panels, or op-
tical elements inside the projector. Such condition may de-
grade the quality of the projected image.
When the symptoms above are noticed, contact your autho-
rized dealer or service station for proper cleaning.
