7.

Refit the filter case by aligning and inserting it into 
the projector slot.

8.

Press the case back until it clicks into place.

9.

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 below 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.

How to replace 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.

Please check
