Regarding the safety bypass proceedure, can someone please tell me if the switch on the n3 is on the main unit or the brain? And is there more than one silver foil tab that can be peeled back (as to not get the wrong one) I haven't looked for it myself yet, and wanted to save time as they are both in places not easy to access. Also is it to the right the switch gets moved ? Thanks Nemodog
