Haesslich is correct. As far as I can see and from the configuration changes I have made, you can only make one change per battery connection/change. So in order to change 3 things you will have to screw on the batt tube while holding the button, make you change, then repeat for the second and third changes. Not a problem at all and goes very fast. Still works better than making changes in the Arc 4 etc IMHO.
Thanks.
