Pairing

Bluetooth Smart ® heart rate sensor or mobile device (smartphone, tablet) has to be paired with your A300 for them to function together. Pairing only takes a few seconds, and ensures that your A300 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 from other devices.

Pair a Heart Rate Sensor with A300

When using the Polar H7 heart rate sensor, A300 may detect your heart rate via GymLink transmission before you have paired the sensor with your A300. GymLink transmission is optimized to be used in swimming, and we recommend using Bluetooth Smart ® transmission in other sports. So, please make sure you have paired your heart rate sensor before training.

  1. Wear the heart rate sensor, and press START in time view to enter pre-training mode.
