5. Select HEART, then press RIGHT to turn it on.
6. When you begin an activity, your watch connects to the sensor and you see a heart icon at the
bottom of the screen.
When your watch is trying to connect to the sensor, the heart flashes.
The first time your watch tries to connect to your sensor, if it finds more than one sensor, your
watch doesn't know which sensor to connect to. Move to a place where there are no other
sensors within range of your watch.
When you have connected to your sensor once, your watch always reconnects to your sensor.
While you train, you can choose to show your heart rate.
You can also use a training program to train to a target heart rate zone.
You can also use the external Heart Rate Sensor with other Bluetooth® Smart Ready devices and
apps. See the documentation that comes with your product or app for more information.
To change the CR2032 battery on the sensor, use a coin to open the back of the sensor. The battery
must be recycled or disposed of according to local laws and regulations.
