Hi.
        I can give you only a consideration: probably the PS manufacturer
makes an unique PS and the case manufacturer puts the switch according
to the destination country. If problems would have appeared, it would
have been noticed.
        You can test with a 115/230 transformer, although this leaves
out the 50/60 Hz thing, if you want to be rigorous.

Starting point:        (-1)^(-1) = -1
Applying logarithms: (-1)*ln(-1) = ln(-1)
Since ln(-1) <> 0, dividing:  -1 = 1
