Pairing Your Wireless Sensors

The first time you connect a wireless sensor to your watch 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.

  1. If you are pairing a heart rate monitor, put on the heart rate monitor. The heart rate monitor does not send or receive data until you put it on.
  2. Bring the watch within 3 m (10 ft.) of the sensor.

NOTE: Stay 10 m (33 ft.) away from other wireless sensors while pairing.

  1. Hold UP.
  2. Select Sensors & Accessories > Add New.
  3. Select an option:
    • Select Search All.
    • Select your sensor type.

After the sensor is paired with your watch, the sensor status changes from Searching to Connected. Sensor data appears in the data screen loop or a custom data field. You can customize the optional data fields (Customizing the Data Screens).
