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.
