Maintenance and Cleaning
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.
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.

environments may cause poor image quality .
When using the projector under dusty or smoky conditions,
