My daughter has a Swim 2 watch and when I go to User Settings for the watch and into Heart Rate Zones, I'm giving the option to set the Training method to one of three options (perc of max heart rate, perc of hr reserve and perc of lactate threshold).
When I pick perc of max heart rate, I cannot set the max heart rate. The Reset button is grayed out and there is a message at the bottom saying the current device does not support custom heart rates.
Where can I update the max heart rate?
