It's to switch the input voltage if you were to travel overseas or use it overseas. UK = 220v from outlets, US = 120v from outlets.

If you're in US, keep it to the 130 setting.

+1 It's just the input voltage selector. A lot of good units automatically detect but quite a bit of units in the market still have this little selector.
