Voltage selector
The system’s power supply unit has a 115V / 230V voltage selector located below
the power connector. Use this switch to select the appropriate system input voltage
according to the voltage supply in your area.
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.
Setting the switch to 115V in a 230V environment or 230V in a 115V
environment will seriously damage the system!
