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 LAMP indicator
turns red and the WARNING TEMP indicator blinks 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? Replace the filter with a new one.

The projector is shut down; and the LAMP indicator is

lighting and other four indicators are blinking.

When the projector detects an abnormal condition, it will
be automatically shut down to protect the inside of the
projector and the LAMP indicator lights on and other four
indicators 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 lighting and blinking, 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
