Cleaning the Air Filter
✔ Note: Clean the air filter about every 100 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. If the filter cannot be cleaned and needs to be replaced,
please consult your dealer.
