Indicators

Warning Indicator

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 is automatically shut down to

avoid overheating. 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

ventilation slots 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.

– Are the air filters clean? Clean the air filters periodically.
