The Rally™ 110/210 pedals must be calibrated periodically to ensure the accuracy of power readings. By default, the pedals are automatically calibrated when idle, such as while you are getting ready for your ride.

When connected to a compatible Garmin^® watch or cycling computer, the Rally 110/210 pedals can detect when a calibration is needed and send a notification.

When prompted to manually calibrate the pedals, you should make sure the bike is completely still and upright, and nothing is touching the pedals, before following the on-screen instructions to complete the calibration.
