• Replace both filters at the same time.
• Before replacing the filters, remove dust and dirt from the pro-
jector cabinet.
• The projector contains high-precision parts. Keep out dust and
dirt during filter replacement.

membrane.

projector malfunction.

The air-filter sponge prevents dust or dirt from getting the inside
of the projector and should be cleaned after every 100 hours of
operation (more often in dusty conditions). If the filter is dirty or
clogged, your projector may overheat.
CAUTION
• Turn off the power, wait for 90 seconds, turn off the main power and
unplug the projector before replacing the filter.
• Do not attempt to operate the projector without filter.
• Your projector will not operate unless the filter cover is installed cor-
rectly.

menu. See page 8-14.
