[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 <STANDBY> 

button on the remote control is pressed or when 

approximately four seconds elapse.

■

The lamp goes off and the projection stops.

■

z

The power indicator <POWER> goes off while 

the cooling fan continues to rotate, and the 

standby indicator <STANDBY> flashes.

■

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 <STANDBY> 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.

When you turn off the power using the power 

 button on the control panel or the power 

<STANDBY> 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).

Check that key lock is off in the [Security] menu.

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.

You can disconnect the power cord, turn off the power 

by the power breaker switch, etc. without pressing the 

power <STANDBY> 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.

■

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.

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.

The factory default setting is [Off]. For details, refer
