I need to re-calibrate my watch for walking or treadmill. It calibrated wrong the first time as I put miles vs KM. So it does not calculate properly. I don’t know how to get the calibrate & save feature to show up on my Venu 2 Plus.

During your activity, wait until you have reached a distance of 1.5km (1 mile) and make sure this distance is showing on the watch (not necessarily the treadmill). Once you have met this distance you will see the option to manually calibrate upon stopping the activity. Swipe up and select Calibrate & Save, and enter the treadmill distance on your watch. For details on this process please refer to: Calibrating the Treadmill Distance.
