-7-
The projector provides 2 temperature sensor ICs, 1 thermistor, and 1 wind sensor on the intake duct. These devices
are monitoring the surrounding temperature of the lamp, panel and intake duct, and the wind sensor is monitoring
airflow passed through the air filter in the intake duct.
- Internal temperature sensor A (IC1692) (around the Intake duct)
- Internal temperature sensor B (IC1816) (around the lamp house)
- Internal temperature sensor C (IC1814) (around the panel/prism)
- Wind sensor D (S901) (intake duct)

The projector is shut down and the WARNING TEMP. indicator
is blinking red.
When the temperature inside the projector reaches a certain level,
the WARNING TEMP. indicator starts blinking. If the temperature
rises moreover, the projector will be automatically shut down to pro-
tect the inside of the projector, and the WARNING TEMP indicator is
blinking fast and the POWER indicator is blinking. When the projec-
tor has cooled down enough (to its normal operating temperature),
the POWER indicator stops blinking and 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 projec-
tor 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.
