Your projector uses nominal input voltages of 100-120 VAC. The projector
automatically selects the correct input voltage. The projector 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. Consult your authorized dealer or service station if you are not sure
what type of power is supplied to your building.
