Cleaning the Filter
The air-filter sponge keeps dust and dirt from getting inside the projector and should be frequently cleaned. If the
filter is dirty or clogged, your projector may overheat.
WARNING

result in fires.

clean the filter. The time to clean the filter is set to [10000 H] at time of shipment.
To cancel the message, press any button on the projector cabinet or the remote control.
