Cleaning the Filters
The projector uses three filters to keep the fans free of dust and other particles, and should be
cleaned every 500 hours of operation. In dusty environments, it is recommended to clean the filters
more frequently. If the filter is dirty or clogged, your projector may overheat. When the message be-
low is displayed, the filters must be cleaned.
Note:
When the Please clean filter message is displayed, please clean all three filters at the same time to
synchronize the Filter time display.
The Filter Message item should be enabled in the Options menu.
Refer to the following guide to clean the filters.
1.
The left-side and rear filters can be
cleaned as demonstrated in the fol-
lowing images.
Note:
Only clean the outside of the
exhaust vents with a vacuum
cleaner.
2.
The rear exhaust vent can be
accessed as shown.
3.
Gently slide the flter holders in the
direction shown.
