Optical hr rate sensor doesn't turn back on

When I connect my strap for a workout and I disconnect it afterwards, the optical hr sensor doesn't take back over.  I have to restart the watch to start the optical sensor again. 

  • I am sorry you have the issue. Please ensure your watch software is fully up to date and showing v15.77. Your OHR should always enable itself again after your OHR strap is no longer being worn. Since your OHR sensor is not taking over automatically again, either reset step might resolve the issue.

    Please try the following:

    - Hard reset your watch by holding down your top left button until your watch shuts off then let go of the button.

    If you still have the issue, please reach out to Outdoor Product Support in your region.
