dust may accumulate on a lens, liquid crystal panels, or op-
tical elements inside the projector. Such condition may de-

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
affect 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.
