Replacing The Filter - BenQ PU9730 User Manual

Replacing the filter
Dirtiness and replacement time for filters varies with the environment. Please check the filter
regularly to get the best projector performance.
Caution:
A dirty filter impedes volume of air flowing into the projector which, in turn, leads to system protection enabling or
component damage caused by overheating. Please check, remove dust or replace the filter.
1. Open up the left or right front filter cap.
2. Remove the used filter.
3. Insert a new filter.
4. Cap the front cover and it's done.
