2.12 Power supply unit information
The system comes with a 250W power supply unit (PSU).
2.12.1 Voltage selector
The PSU has a 115V/230V voltage selector switch located beside the
power socket. Use this switch to select the appropriate voltage according
to the voltage supply in your area.
Setting the switch to 115V in a 230V environment will seriously
damage the system!
The voltage selector is set to 230V by default.
If the voltage supply in your
area is 100-127V, set the
switch to 115V.
If the voltage supply in your
area is 200-240V, set the
switch to 230V.
