Operating Requirements
All machines require two power inputs: one on the system unit
and one on the monitor display.
The system unit comes with a voltage selector switch, allowing
selection of either 115 V ac or 230 V ac. This switch must be in
the 115V ac position when the machine is plugged into a 100 –
127 V ac electrical outlet, and 230 V ac position when the
machine is plugged into a 200 - 240V ac electrical outlet.
