Voltage Switch - 42
Voltage Switch
The power supply is not self-configuring for different input
voltages. The voltage switch is delivered preconfigured for
the input voltage of the region in which the unit is originally
purchased. If the computer is moved to another location
where the input voltage is different, a voltage switch
must
be adjusted to accommodate the voltage change. The switch
has two positions that support voltage ranges of 100 to 130
V or 220 to 270 V.
