TO MAINTAIN THE LIFE OF THE LAMP, ONCE YOU TURN
THE PROJECTOR ON, WAIT AT LEAST FIVE MINUTES
BEFORE TURNING IT OFF.
Power off? disappears after 4 seconds.
Turning Off the Projector
Press the POWER button on the remote controller or
on the top control, and Power off? appears on the
screen.
Press the POWER button again to turn off the projector.
The POWER indicator starts to blink red, and the
cooling fans keep running. (You can select the level of
fans’ quietness and speed. See “Fan” on page 63.) At
this time, you can unplug the AC power cord even if the
fans are still running.

When the projector has cooled down enough, the
POWER indicator stops blinking and you can turn on
the projector.
Note:
• When the Direct power on function is set to On, the
projector will be turned on automatically by connecting
the AC power cord to an AC outlet. (p. 59)
• The running speed of cooling fans is changed according
to the temperature inside the projector.
• Do not put the projector in a case before the projector is
cooled enough.
• If the WARNING TEMP. indicator blinks or lights red,
see “WARNING TEMP. indicator” on page 66.
• While the POWER indicator is blinking, the lamp is
being cooled down and the projector can not be turned
on. Wait until the POWER indicator stops blinking to turn
on the projector again.
• The fan rotation will terminate directly if the AC power
cord is unplugged immediately after the projector is
turned off.
• The projector can be turned on after the POWER
indicator turns red. The waiting time to restart will be
shortened when the normal power-off processing for fan
cooling is completed, compared with the time the AC
power cord is immediately unplugged after the power-
off.
• To protect the component parts inside the projector, the
fans normally start running again in approximately 40
seconds after turning off the projector. This is NORMAL
operation and not a malfunction.
DO NOT OPERATE THE PROJECTOR CONTINUOUSLY
WITHOUT REST. CONTINUOUS USE MAY RESULT
IN SHORTENING THE LAMP LIFE. TURN OFF THE
PROJECTOR AND LET STAND FOR ABOUT AN HOUR IN
EVERY 24 HOURS.
Basic Operation
You can disconnect the power cord from the
wall outlet or turn off the breaker even during
projection without pressing the POWER button.
Note:
• When using the Direct Power Off function,
you can not restart the projector immediately
after the power is disconnected. If the external
power supply is suddenly cut off, the fans
stop immediately. The lamp remains high
temperature and needs to be cooled.
