The WARNING indicators show the state of the function which protects the projector. Check the state of the
WARNING indicators and the POWER indicator to take proper maintenance.
Warning Indicators
The projector is shut down and the WARNING
TEMP. 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.
✔
Note:
•The WARNING TEMP. indicator continues to blink even after the
temperature inside the projector returns to normal. When the
projector is turned on again, the WARNING TEMP. 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 the air
vents of the projector 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.
– Is the filter clean? Clean the filter periodically or replace it
with a new one.
The projector is shut down and all five indicators
are blinking.
When the projector detects an abnormal condition, it will be
automatically shut down to protect the inside of the
projector and all five indicators on the top panel blink. In this
case, unplug the AC power cord and plug it, and then turn
on the projector once again to verify operation. If the
projector cannot be turned on and these indicators are still
blinking, unplug the AC power cord and contact the service
station.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE AC
