You can run the calibration program by shorting out the two pins located behind the small metal panel, fixed with 3 screws, located at the rear of the unit. They are difficult to spot next to the D type socket. Once shorted be careful as the treadmill runs through a inclination cycle and then speed from zero to full throttle.
