Just became owner of a new XP Deus version 5.2. Also bought one of the HF coils for it. Read through the owners manual and watch a lot a Gary's videos on it and think I've got it but just want some confirmation this is right. If I install a new HF coil while the remote control is on it will automatically accept the new coil and will become #2 coil in the menu? Unless your just using the backphones then it needs to have the serial number put into them as well?
