Regular maintenance
Clean the projector when it is contaminated by foreign matter or its display effects are get-
ting worse.
Note:
Unplug the AC power cord before any cleaning operation.
Note:
Do not operate the projector after its filter is removed. Dust may attach to the lens
assembly and deteriorate image quality.
Clean the lens
Wipe the lens with clean cloth dampened with
non-abrasive camera lens cleaner or clean it
with lens cleaning paper or air blower.
Do not over apply cleaner to the lens. Abrasive
cleaner, solution, or other rough chemical may
scratch the lens.
Clean the filter
The filter is designed to keep dust from entering
in the projector, which may lead to dusts accumu-
lated on surface of internal components. Clogged
filter may reduce cooling fan effects, which, in
turn, will overheat the projector and shorten its life
cycle. Clean the filter immediately whenever the
Filter Warning icon displays.
Please follow these steps to clean the filter:
1 Power off the projector and unplug from AC
power source.
2 Remove the control panel by release the screw
on it.
3 Remove the filter by release the screw on the
filter case.
3 Gently clean it with a brush.
4 Insert the filter. Make sure it has been fully
inserted.
Clean casing of the projector
Wipe the casing surface with clean and soft cloth.
Gently wipe the casing with clean and soft cloth
dampened with small amount of neutral detergent
to remove heavy dirt. Do not over apply cleaner
to the casing. Abrasive cleaner, solution, or other
rough chemical may scratch the casing surface.
Place the projector in proper container after use to
protect it from dirt and dust and being scratched.
