How to reset my H9/H10 heart rate sensor?
As a troubleshooting method, a reset for the sensor can help.
To reset your heart rate sensor:
- Remove the battery.
- Press the metal snaps that attach to the strap with your fingers for at least 10 seconds.
- Wait 30 seconds and then put the battery back in.
Sensor pairing with a Polar or third-party device or app is required after a reset, update, or battery replacement if you are using a firmware version earlier than 3.3.1 for H10 and 1.2.1 for H9.
