Precautions During Battery-powered Operation
Note the following precautions while the projector is being powered with the battery.
 If there is no input signal to the projector while projection is in progress, the projector will
automatically go into low-power projection and the Light Control setting (page 48) will change to 1
(dimmest). In order to minimize battery power consumption, the Light Control setting cannot be
changed from 1 until an input signal is received again. When an input signal is received by the
projector, the Light Control setting will return to the setting it was at before the input signal stopped.
You can change this setting at this time, if you want.
 Projector power will turn off automatically if no key operation is performed and there is no input
signal to the projector for about five minutes under battery power, regardless of the current Auto
Power Off setting (page 35).
