Maintenance and cleaning

Warning indicator

The ALERT indicator shows the state of the function which protects the projector. Check the state
of the ALERT indicator and the POWER indicator to take proper maintenance.
The projector is shut down and the ALERT
indicator is blinking red.
When the temperature inside the projector
exceeds the normal temperature, the projector
is automatically shut down to protect internal
components. 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 button.
 Note:
The ALERT indicator continues to blink
even after the temperature inside the
projector returns to normal. When the
projector is turned on again, the ALERT
indi cator stops blinking.
Check the items below:
– Did you provide appropriate space for the
projector to be ventilated?
Check the installing condition to ensure
ventilation slots are not blocked.
– Has the projector been installed near the
duct or vent of an airconditioning?
Move the installation of the projector away
from the duct or vent.
– Are the air filters clean? Clean the air filters
periodically.
The projector is shut down and the ALERT
indicator lights red.
When the projector detects an abnormal
condition, it is automatically shut down to
protect the internal components and the
ALERT indicator lights red. In this case, unplug
the AC power cord and plug it in again, and
then turn on the projector once again to verify
operation. If the projector cannot be turned on
and the ALERT indicator lights red, unplug the
AC power cord and contact the service station
for servicing and maintenance.
Caution
Do not leave the projector with the AC power cord connected under an abnormal condition.
It may result in fire or electric shock.
