Power  
button
1)  Press the power  button on the 
control panel or the power  
button on the remote control.
■
z [Power off ?] is displayed on the screen.
■
z The screen display will disappear when any 
button other than the power 
 button on 
the control panel and the power  
button on the remote control is pressed or when 
approximately four seconds elapse.
2)  Press again the power  button 
on the control panel or the power 
 button on the remote 
control.
■
z The lamp goes off and the projection stops.
■
z The power indicator  goes off while 
the cooling fan continues to rotate, and the 
standby indicator  flashes.
3) 
When the standby indicator 
 comes on, press the 
 
side of the main power switch to turn 
off the power.
Note
■
z Do not turn on the power immediately after turning 
it off.
In the cooling state of the luminous lamp after the 
power is turned off, the lamp may not light up even 
when the power is turned on. In this case, wait for 
the standby indicator  to turn red, and 
then turn on the power again. Turning on the power 
while the lamp is still hot may shorten the lamp life.
■
z When you turn off the power using the power 
 button on the control panel or the power 
 button on the remote control with the 
main power switch on the projector body turned 
on, the projector continues to consume electricity. 
For details on power consumption, refer to “Power 
consumption” (
 page 114).
■
z Check that key lock is off in the [Security] menu. 
(
 page 79)
■
z If you use the projector for longer than 24 hours, 
turn off the power every 24 hours and wait for one 
hour. This will increase the lamp life.
Direct power off function
You can disconnect the power cord, turn off the power 
by the power breaker switch, etc. without pressing the 
power  button on the remote control or 
the main power switch on the projector.
This is useful in cases where the switch is not easily 
accessible, such as when the projector is ceiling 
mounted. This function also provides safety if a power 
outage occurs or if the power cord is accidentally 
disconnected from the outlet immediately after turning 
off the power.
Note■
z When the lamp has been cooled by the direct 
power off function, it sometimes takes longer than 
usual for the lamp to light up again.
Power management function
The projector has a power management function. If no 
signal is detected for 30 seconds and no operation is 
performed on the projector, [No signal] and the timer 
appear on the screen and a countdown starts.
If the countdown is completed without a signal being 
input or an operation on the projector, this function 
works to save power and extend the service life of the 
lamp.
Note■
z The factory default setting is [Off]. For details, refer 
to [Power management] (
 page 78).
