							Basic Operation
Press the ON/STAND-BY button on the top control or 
on the remote control, and “Power off?” appears on 
the screen.
Press the ON/STAND-BY 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 the fans’ quietness and running speed. See page

even if the fans are still running.

2
TO MAINTAIN THE LAMP LIFE, ONCE YOU TURN 
THE PROJECTOR ON, WAIT AT LEAST 5 MINUTES 
BEFORE TURNING IT OFF.
3When the projector has cooled down enough to be 
turned on again, the POWER indicator stops blinking.
“Power off” disappears after 4 seconds.
✔Note:
• When the On start function is “On,” this projector is 
turned on automatically by connecting the AC power cord 
to an AC outlet (p. 50).
•  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 indicator blinks or emits a red light, see 
“Warning Indicator” on page 60.
•  While the POWER indicator is blinking, the lamp is being 
cooled down and the projector cannot 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.
