Pairing Your Wireless Sensors
The first time you connect a wireless ANT+® or Bluetooth® sensor to your Garmin® device, you must pair the device and sensor. After they are paired, the device 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 device automatically when you start an activity with the sensor turned on and near the device.
