Pairing

Before taking a new mobile device (smartphone, tablet), heart rate sensor, stride sensor or Polar Balance scale into use, it has to be paired with your M430. Pairing only takes a few seconds, and ensures that your M430 receives signals from your sensors and devices only, and allows disturbance-free training in a group. Before entering an event or race, make sure that you do the pairing at home to prevent interference due to data transmission.
