Information
The Warning indicator shows the state of the function which protects the projector. Check the state of the 
Warning indicator and the POWER indicator to take proper maintenance. 
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 will be 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  enough (to  its normal  operating 
temperature), it can be turned on again by pressing the ON/
STAND-BY button.
The projector is shut down and the Warning 
indicator lights red.
When  the  projector  detects  an  abnormal  condition,  it  is 
automatically shut down to protect the inside of the projector 
and the Warning indicator lights red. In this case, unplug the 
AC power cord and reconnect it, and then turn the projector 
on once again to verify operation. If the projector cannot be 
turned  on  and  the  Warning indicator  still  lights  red,  unplug 
the AC power cord and contact the service station. 
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE 
AC POWER CORD CONNECTED UNDER AN 
ABNORMAL CONDITION. IT MAY RESULT IN 
FIRE OR ELECTRIC SHOCK.
