I always carry the
Doug Ritter Special Edition MkII Photon Freedom Micro on my keyring upside down in the hands free kit holder so the button can't be depressed by accident.
I was suprised to take the keyring out of my pocket with it switched on this morning and found that be pressing the back I can turn it on and off.
I can't with the other 2 I carry and it's the only one I've changed the batteries with.
Any suggestions?
