Maintenance and Cleaning
Cleaning the Filters
Filter prevents dust from accumulating on the optical elements inside the projector. Should the filters become
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. If a "Filter warning" icon appears on the screen, clean the filters
immediately. Clean the filters by following the steps below.
1
Turn off the projector, and unplug the AC power cord
from the AC outlet.
Turn the projector over and remove the filters .
Clean the filters softly by using a brush.
4
Replace the filters properly. Make sure that the filters
are fully inserted to the projector.
CAUTION
Do not operate the projector with the filters
removed. Dust may accumulate on the optical
elements degrading picture quality.
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 you operate the projector . Usage in these
environments may cause poor image quality .
When using the projector under dusty or smoky conditions,
dust may accumulate on a lens, LCD panels, or optical
elements inside the projector degrading the quality of a
projected image. When the symptoms above are noticed,
contact your authorized dealer or service station for proper
cleaning.
