Automatic cleaning ﬁ lter (continued)

How to clean the automatic cleaning ﬁ lter

Check the amount of dust through the dust check

window of the ﬁ lter cover and clean it, if necessary.

Before cleaning the ﬁ lter, be sure to turn off the main

power switch of the projector and unplug the power

cord from the outlet.

• When the dust box of the automatic cleaning ﬁ lter

is ﬁ lled up with dust, the cleaning ability decreases.

If you use the projector in such a state, the ﬁ lter is

covered by the dust and the temperature inside the

product abnormally rises, damaging the internal

parts and components and affecting the panel’s

lifetime, resulting in a breakdown.

• When the temperature inside the projector is

abnormally high, the projector may automatically

turn off and go into the standby mode where the

light source lamps are off to protect the internal

parts and components.

1. Loosen the screw (a) that is securing the ﬁ lter cover

using a Philips screwdriver and remove the ﬁ lter

cover (b) from the projector.
