If you have calibrated your treadmill activities fewer than 6 times, you are asked if you want to calibrate after your treadmill activity if one of the following situations is true:
- The distance of the activity is 400 metres or more.
- The duration of the activity is 1 minute or longer.
- The number of steps in the activity is 60 or more.
If you have already calibrated six treadmill activities but want to calibrate again, move down from the pause screen in your current activity and select CALIBRATE .
