Hi, Have had a True PS 800 treadmill with orthotic belt for years. I moved, and when I tried to calibrate it, tonight it rises, but it doesn't appear to get up to max speed, just goes back down and gives "fail 2" . I planned on calling true on Monday but it's irritating I can't find this error anywhere. I did try to shut it off and turn it back on to try again. Same result. Wires appeared to be in firmly. Ideas?
