Replacing the Air Filter
The air filter should be replaced periodically. When
“Please replace the filter.” appears on the screen,
replace the air filter immediately.
Notes
• Replacing the air filter is very important to maintain the high
efficiency of the projector and to prevent a malfunction. When
the replacement message appears on the screen, replace the air
filter without delay.
• When removing the air filter from the projector, be careful that
no dust or object gets into the inside of the projector.
• Before replacing the air filter, turn off the projector and unplug
the power cord.
1 Hold down the adjuster lock lever, slide it
to the right, raise the rear of the projector,
then return the adjuster lock lever. While
keeping the screw on the bottom of the
projector turned inward with a coin or a
slotted screwdriver, open the projector
cover with your hand.
Note
Be sure that the projector is stable.
2 Push the filter lock knob to remove the
filter cover.
3 Remove the air filter from the filter holder
by holding the tab on the air filter.
4 Insert the new air filter into the filter holder
with the white surface up, put the holder
face down, then replace it into the
projector.
5 Replace the filter cover.
6 While pushing the projector cover toward
you by holding both sides of the cover on
the lens side, close the cover until it clicks.
