Next, take the electrodes for behind the ear and stick them to the prepared skin over the bone-bump behind each ear.


People’s hairlines differ greatly in this area so some people may find that – to avoid the adhesive getting caught in the hair – part of the electrode sticker must come up and adhere to the back of the ear. This is ok, just make sure that the centre part of the electrode is over the bone-bump.


The left ear electrode inserts into the M1 port on the far right of the top of the head box, and the right ear electrode inserts into the M2 port on the far left of the top of the head box – unlike other earlier inputs in this set up, it is important that left and right aren't confused here. (use the diagram on the headbox to help)
