MMM & DX3R Programming

I have everything soldered and connected, When going through initial setup I can get the Monster to find full throttle and full brake/reverse, I can not seem to get that final programming in of neutral.

I set defaults on the radio for this model before I even began. I am starting to play around with the deadband settings. Does anyone know the secret to get past this final sequence so i can see just how well this sucker works?
