Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter become
clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup and
adversely affect the life of the projector. If a “Filter warning” icon appears on the screen, replace the filter immedi-
ately by following the steps below.

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 using the projector under dusty or smoky conditions,
dust may accumulate on a lens, or optical elements inside
the projector degrading the quality of a projected image.
When the symptoms above are noticed, clean up the lens
or other optical parts by referring to the chapter "Cleaning
the projector".
