CAUTION
Do not operate the projector with the filter
removed. Dust may accumulate on the optical
elements degrading picture quality.

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.
