Turning Off the Wrist-based Heart Rate Monitor
The default value for the Wrist Heart Rate setting is Auto. The watch automatically uses the wrist-based heart rate monitor unless you pair a compatible heart rate monitor with ANT+® or Bluetooth® technology to the watch.
NOTE:
Disabling the wrist-based heart rate monitor also disables the wrist-based pulse oximeter sensor.
