If your Automatiq system won't calibrate, try updating the settings on the hub interface using a model-specific QR code as shown in this video: https://www.youtube.com/watch?v=LgSC20JTfG4
Please click on the link below that corresponds to the model of your bike to open the QR code.
If the Wheel Speed Too Slow error persists, then the outer spline nut should be tightened and encoder rings inspected.
Check that all of the magnets on the back side of your encoder rings are still present and in the correct orientation.
