Voltage Switch
The voltage switch must be
set correctly to avoid
damaging the computer.
Insert a screw driver in the
slot to set the switch to show
“115” for voltages between
100 and 130. Set the switch
to show “230” for voltages
between 200 and 270. Some
countries use two
standardized voltages. If you
aren’t sure which voltage is
available, check with the
electricity supply company
before plugging in the
computer.
