operating a projector. Usage in these environments may
cause poor image quality.

accumulate on liquid crystal panel, lens, or optical elements inside
it. This condition may degrade quality of projected image.
When above symptoms are noticed, contact your authorized
dealer or service station for proper cleaning.

Air Filter ReplacementAir filter
Air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the air filters
become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat build up and
adversely affect the life of the projector. Proper maintenance should be taken.
