When the temperature inside the projector reaches a

• 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.
