6. Refit the filter case by aligning and inserting it into
the projector slot.
7. Press the case back until it clicks into place.
8. Turn the projector back on.
If the case is not correctly seated in place, the
projector will display an on-screen message as
pictured to the right every three minutes.
The message will display 3 times for a 10-second
duration each, if no further action is taken.
Then a second message as pictured to the right
displays to warn of shutdown in 1 minute.
You can re-attach the case correctly anytime before
the projector shuts down. That means you have 10-
11 minutes to get the re-attachment done from the
time the first warning message was displayed. The
projector will return to normal operation.
Replacing the filter sponge
If you find the dirt is hard to remove from the filter sponge or the sponge is broken, replace
it.
1. Carefully peel the filter sponge away from the filter case.
See that there are small plastic pins along the edges to
position and retain the sponge into place. Lift the sponge
up off these pins taking care to prevent them from
breaking off.
2. Attach the supplied new filter sponge to the filter case.
Make sure that the tiny holes securely fit onto the case's
pins.
