							Cleaning the Air Filter
To ensure proper ventilation of your projector, the air filter should be periodi-
cally cleaned.  More frequent cleaning may be required if you use your projec-
tor in a dusty or dirty environment.
Caution:  If the air filer is not cleaned properly, it can become clogged with
dust and prevent proper ventilation.  This may cause overheating and
damage the projector.
Important:  If the filter cannot be cleaned or becomes damaged or torn, it
should be promptly replaced with a certified replacement part.  Contact your
local dealer of products for additional information.
1. Turn off the projector and wait for the fan stop.
2. Unplug the projector.
3. Turn the projector on its side so that the connection panel is facing up-
ward.
Note:  Standing the projector on its side keeps dust from getting inside.
4. Locate the air filter cover on the bottom of the projector and slide the cover
latch downward to remove the cover.
5. Use a softbrush to clean the air filter being carefully not to tear the filter or
loosen it.
Caution:  Installing a wet or damp air filter may damage your projector.
6. Replace the air filter cover on the projector.  Make sure that it clicks into
place.
Caution:  Never replace the air filter cover without the air filter attached;
dust may get into projector without this filter.  Never operate your projector
without the air filter cover in place because this may damaged your
projector with dust.
