Pairing Your Wireless Sensors
Before you can pair, you must put on the heart rate monitor or install the sensor.
The first time you connect a wireless sensor using ANT+® or Bluetooth® technology, you must pair the watch and sensor. If the sensor has both ANT+ and Bluetooth technology, Garmin® recommends that you pair using ANT+ technology. After they are paired, the watch connects to the sensor automatically when you start an activity and the sensor is active and within range.
TIP:
Some
ANT+ sensors pair with your watch automatically when you start an activity with the sensor turned on and near the watch.
