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 below is displayed, the filters must be cleaned.
Note:
When the Please clean filter message is displayed, please clean or replace 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 Option on page
83 .
Refer to the following guide to clean the filters.
1.
Lift the projector to expose the under-
side to locate the first filter.
See the drawing on the right.
Note: Only clean the outside of the ex-
haust vents with a vacuum cleaner.
