We recommend avoiding dusty/smoky environment when operating the projector. Operating in these environments
may cause poor image quality.
When using under dusty or smoky conditions, dust may accumulate on the lens, liquid crystal panels, or optical elements
inside the projector. This condition may degrade the quality of a projected image.
When the above symptoms are noticed, contact your authorized dealer or service station for proper cleaning.
