14.4 Cleaning and Replacing the Dust Filters
The filters must be cleaned regularly to allow an efficient air intake. Otherwise, dirt may enter the unit and
appear on the screen, preventing you from enjoying the video fully. If dirt has entered the unit or if you need
information about the filter, please consult your authorized dealer. A filter cleaning warning appears every
500 hours.

detergent is recommended. Insert the filters in their original positions and make sure that the claws are firmly
inserted.
