You "might" be able to have a Tech walk you though it on the phone. Be prepared for a time consuming and tedious phone call. Could be a few hours. It's easy with a Tech on the spot, but there are steps you can miss that can mess it up if trying on your own. That's why usually, it's a tech visit.
Head 1 is easy peasie. Two and three are harder. More steps. If it's head two or three, then not only is it more challenging, but then calibration must be done and that is a tech visit.
