Press the POWER ON-OFF button on the top control or on
the remote control, and the message "Power off?" appears
on the screen.
Press the POWER ON-OFF button again to turn off the

TO MAINTAIN THE LIFE OF LAMP, ONCE YOU TURN
THE PROJECTOR ON, WAIT AT LEAST 5 MINUTES
BEFORE TURNING IT OFF.
DO NOT UNPLUG THE AC POWER CORD WHILE THE
COOLING FANS ARE RUNNING OR BEFORE THE
POWER INDICATOR STOPS BLINKING. OTHERWISE IT
WILL RESULT IN SHORTENING THE LAMP LIFE.

When the projector has cooled down enough to be turned on
again, the POWER indicator stops blinking and turns to
steady red. Then you can unplug the AC power cord.
The message disappears after 4 seconds.
✔Note:
• You cannot turn on the projector during the cooling period with the POWER
indicator blinking red. Turn it on after the POWER indicator stops blinking and turns
to steady red.
• When the On start function is on, the projector is turned on automatically by
connecting the AC power cord to an AC outlet. (See page 41 for the On start
function.)
• Do not operate the projector continuously without rest. Continuous use may result in
shortening the lamp life. Turn off the projector and rest it for about an hour in every
24 hours.
• The running speed of cooling fans is changed according to the temperature inside
the projector.
• If the WARNINGindicator blinks or turns red, see “Warning Indicator” on page 45.
