To replace the ﬁlter (sponge):

CAUTION

• Replace both ﬁlters at the same time.

• Before replacing the ﬁlters, remove dust and dirt from the projector cabinet.

• The projector contains high-precision parts. Keep out dust and dirt during ﬁlter replacement.

• Do not wash the ﬁlter with water. Water will damage the ﬁlter membrane.

• Reattach the ﬁlter cover correctly. Failure to do so may cause projector malfunction.

Preparation: Replace the lamp before replacing the ﬁlters.

NOTE: When you replace the lamp, it is also wise to replace the ﬁlter. The ﬁlter comes in the same package with your replacement lamp.

1. Remove the ﬁlter cover by pushing down on the catch of the cover until you feel it detach.
