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.
If the projector reaches a time set in the timer setting, a Filter warning 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 as soon as possible.

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.

rized dealer or service station for proper cleaning.
