Cleaning the Air Filter
✔
Note: Clean the air filter about every 50 hours or if the message “CHECK AIR FLOW” is
displayed on the screen. If air is restricted due to dust accumulation on filter, the
projector may overheat and shut down automatically.
Turn off the MAIN POWER SWITCH of the projector and pull out power cord. Let cool for
20 minutes. Vacuum dust and dirt from filter.
