Maintenance and cleaning
89
Clean your projector only using the below
guidelines.
Clean the lens
Wipe the lens with clean cloth dampened with
non-abrasive camera lens cleaner or clean it
with lens cleaning paper or compressed air.
Do not over apply cleaner to the lens. Abrasive
cleaner, solution, or other rough chemical may
scratch the lens.
Clean casing of your projector
Wipe the casing surface with clean and soft
cloth. Gently wipe the casing with clean and
soft cloth dampened to remove heavy dirt.
Do not over apply cleaner, abrasive cleaner,
solution, or other rough chemical that may
scratch the casing surface.
Place your projector in proper container after
use to protect it from dirt and dust and being
scratched.
Clear the filter
The filter is designed to keep dust from
entering in your projector, which may lead
to dusts accumulated on surface of internal
components. Clogged filter may reduce
cooling fan effects, which, in turn, will overheat
your projector and shorten its life cycle. Clean
the filter immediately whenever the Filter
Warning icon displays.
Please follow these steps to clean your filter:
1. Power off your projector and unplug from
AC power source.
2. Remove the filter.
3. Gently clean it with a brush.
4. Replace the filter. Make sure it has been
fully inserted.
Note
Do not operate your projector
after its filter is removed. Dust
may attach to the lens assembly
and deteriorate image quality.
Do not allow objects to enter the
air outlets. Allowing objects to
enter the projector will cause the
projector to fail.
Note
Unplug the AC power cord before
any cleaning operation.
