Caution
Do not operate the projector with
the air filter removed. Dust may
accumulate on the optical elements,
degrading picture quality.
Do not put any small objects into the
air intake vents. Otherwise, it 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 you use the projector under dusty or
smoky conditions, dust may accumulate on the
lens, LCD panels, or optical elements inside the
projector. When the symptoms above are
noticed, contact your authorized dealer or
service station for proper cleaning.
