x Replacing or Cleaning the Filter
To replace the filter:
• 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.
• 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.
1. Pull out the filter cover by pushing up on the catch.
The "Please clean the filters" message will be displayed each
time the projector is turned on after it has been used in excess of
168 hours. Should this message appear, clean the filters.
NOTE:
* The message can be turned on or off using the "Message" option on the Setup
menu. See page 8-14.
* After cleaning the filters and resetting the filter usage time back to zero, the mes-
sage will not be displayed.
See page 8-17 for resetting the filter usage time.

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 (2 minutes in the optional ex-
tended life lamp GT60LPS), 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.
To clean the filter:
Pull out the filter by pushing up on the catch. Vacuum the filter-
through the filter.
