Setting
The WARNING indicator shows the state of the function which protects the projector. Check the
state of the WARNING indicator and the POWER indicator to take proper maintenance.
Warning Indicator
The projector is shut down and the WARNING
indicator is blinking red.
When the temperature inside the projector reaches a
certain level, the projector is automatically shut down
to protect the inside of the projector. The POWER
indicator is blinking while the projector is being cooled
down. When the projector has cooled down sufficiently
(to its normal operating temperature), it can be turned
on again by pressing the POWER ON/STAND-BY
button on the top control or on the remote control.
✔ Note:
The WARNING indicator continues to blink even
after the temperature inside the projector returns
to normal. When the projector is turned on again,
the WARNING 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 the 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. (p.52)
The projector is shut down and the WARNING
indicator emits a red light.
When the projector detects an abnormal condition, it
is automatically shut down to protect the inside of the
porjector and the WARNING indicator becomes red. In
this case, disconnect the AC power cord and reconnect
it, and then turn the projector on once again to verify
operation. If the projector cannot be turned on and the
WARNING indicator emits a red light, disconnect the
AC power cord and contact the service station.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE
AC POWER CORD CONNECTED UNDER THE
ABNORMAL CONDITION. IT MAY RESULT IN
FIRE OR ELECTRIC SHOCK.
