This projector uses nominal input voltages of 100–120 V or
200–240 V AC and it automatically selects the correct input
voltage. It is designed to work with single-phase power
systems having a grounded neutral conductor. To reduce the
risk of electrical shock, do not plug into any other type of
power system.
If you are not sure of the type of power being supplied,
consult your authorized dealer or service station.
Connect the projector with all peripheral equipment before
turning the projector on.
CAUTION
For safety, unplug the AC power cord when the projector
is not in use. When the projector is connected to an outlet
with the AC power cord, it is in stand-by mode and
consumes a little electric power.

Connecting the AC Power Cord

projector.
The AC outlet must be near this equipment
and must be easily accessible.
