Warning Indicator
The projector is shut down and the WARNING
indicator is blinking red.
When the temperature inside the projector reaches a
certain level, the projector is automatically shut down to
avoid overheating.  The POWER indicator is blinking while
the projector is being cooled down.  When the projector has
cooled down enough (to its normal operating temperature),
it can be turned on again by pressing the POWER ON-OFF
button.  
Note:
• After the temperature inside the projector returns to normal, the 
WARNING indicator still continues to blink.  When the projector is 
turned on again, the WARNING indicator stops blinking. 
Then check the matters below:
– Did you provide appropriate space for the projector to be 
ventilated?  Check the installing condition to see if
ventilation slots are not blocked.
– Is the projector not installed near the ventilation duct of
air-conditioning equipment which may be hot? Install the
projector away from the ventilation duct of air-
conditioning equipment. 
– Are the air filters clean?  Clean the air filters periodically.
