Region setting, why?


I purchased a Muse from Amazon in the US and am using it in New Zealand. I’m trying to figure out what region setting to use, and why. Since the Muse is battery powered, does the frequency of the power grid have anything to do with the settings? What settings should I use for an American Muse used here, where the power is 230/240 volts 50 hertz but the Muse is working off of its internal Lithium battery?
