Replacing The Filter; Resetting The Filter Counter - ViewSonic PJL6243 User Manual

Filter prevents dust from accumulating on the optical elements inside the projector. Should the Filter 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, replace the Filter
immediately. Replace the filter by following the steps below.
1
Turn off the projector, and unplug the AC power
cord from the AC outlet.
Place the latch in the OPEN position and pull out

the filter in the arrow direction.
3
Slide the new filter (along the guide rails. Make
sure that the filter is inserted completely.) Place
the latch back in the LOCK position.

Connect the AC power cord to the projector and
turn on the projector.

CAUTION
- Do not operate the projector with the filter
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.
- Do not wash the filter with water or any other
liquid Matter. Otherwise the filter may be
damaged.
RECOMMENDATION

environments when you operate the
projector . Usage in these environments
may cause poor image quality .
When using the projector under dusty or
