Pairing sensors with M450

Before taking a new Bluetooth Smart ® heart rate sensor, cycling sensor or mobile device (smartphone, tablet) into use, it has to be paired with your M450. Pairing only takes a few seconds, and ensures that your M450 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.
