indicator is blinking red .
When the temperature inside the projector reaches a
certain level, the projector is automatically shut down to
protect the inside of the projector. The POWER indicator
is blinking while the projector is being cooled down. When
the projector has cooled down sufficiently (to its normal
operating temperature), it can be turned on again by
pressing the POWER ON/STAND-BY 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.
– Is the air filter clean? Clean the air filter periodically.

be turned on and the WARNING indicator emits a red light,
disconnect the AC power cord and contact the service
station for check and repair.
