When using the Polar WearLink®+ transmitter with Bluetooth® for the first time, you need to pair the transmitter with your receiving device. If the application asks for the PIN code it is 0000. The PIN code is printed also on the back of the connector of the Polar WearLink®+ transmitter with Bluetooth®.
In Sports Tracker application pin code needs to be given within 10 seconds, otherwise the receiving device assumes that the pairing is cancelled.
For more information on enabling the Polar WearLink®+ transmitter with Bluetooth® and starting the application consult separate user instructions supplied by the application manufacturer.
