Direct power off function

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.
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).
