Cleaning the Air Filter
Clean the air filter at the bottom of the projector after every
100 hours of use. If it is not cleaned periodically, it can
become clogged with dust, preventing proper ventilation. This
can cause overheating and damage the projector. To clean the
air filter, follow these steps:
1. Turn off the projector and unplug the power cable from the
electrical outlet.
2. Place the projector on its side with the handle at the top so
that the filter is easily accessible.
Note:
Placing the projector in this position keeps dust from
getting inside the projector housing.
3. Lift up the tab securing the filter and remove the filter.
