In the song scanner mode and the enter network key mode, the knob scrolls the wrong way.  In the song scanner, turning the knob anti-clockwise moves progress forwards and vice-versa.  When entering a network key, anti-clockwise does abcd etc, clockwise goes to the far end of the list.

In everything else I've checked it works as expected.  e.g. clockwise scrolls through items 1-10 in a list in ascending order.
