indicators and the POWER indicator to take proper maintenance.
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

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 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 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 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 center.
