Power off? disappears after 4 seconds.

Press the POWER button on the top control 

or on the remote controller, and 

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 

56.) 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. 



  •  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.51).

  •  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 lights red, 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.

  •  For assisting the cooling fans’ operation, the 

projector is equipped with a large capacitor. While 

the projector is operating, the capacitor charges 

electricity. When disconnecting the AC plug from 

AC outlet, cooling fans start to run 1 minute until 

the capacitor is discharged. 

  •  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. 



  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.

You can disconnect the power cord from the 

wall outlet or turn off the breaker even during 

projection without pressing the POWER 

button.
