Maintenance and Cleaning
Warning Indicator
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.
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
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 POWER ON-OFF
button.
✔
Note:
• After the temperature inside the projector returns to normal, the
WARNING indicator still continues to blink. 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.
– Is the projector not installed near the ventilation duct of
air-conditioning equipment which may be hot? Install the
projector away from the ventilation duct of air-
conditioning equipment.
– Are the air filters clean? Clean the air filters periodically.
(p. 54)
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 and the
WARNING indicator is red. In this case, disconnect the AC
power cord and reconnect it, and then turn the projector on
once again for check. 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 for check
and repair.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE AC
POWER CORD CONNECTED UNDER THE
ABNORMAL CONDITION. IT MAY RESULT IN
FIRE OR ELECTRIC SHOCK.
