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:
•The WARNING indicator continues to blink even after the
temperature inside the projector returns to normal. 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.
– Has the projector been installed near an Air-Conditioning/
Heating Duct or Vent? Move the installation of the
projector away from the duct or vent.
– Are the air filters clean? Clean the air filters periodically.
