Are you holding the outside buttons down, and then pressing the middle button 4 times while continuing to hold the outside buttons? I have had numerous people on the Hogsters and Super Hogsters say they can't get their scopes out of scanner mode, and then someone else does it and they get it on the first try.
I know it sounds silly but have someone else try. Depending on firmware some of the other Hogsters are pressing all 3 buttons at the same time but the Super should be the first way I described. Make sure you hold the outside buttons continuously.
