Polar Beat is compatible with Polar H6 and H7 hear rate sensors.
To optimize sensor battery life, turn off sensor visibility to other compatible devices. Go to Settings →HR Sensor under currently paired HR sensor.
If you are a Polar H7 user, set GymLink ON if you wish to use the sensor simultaneously with other compatible Polar training computers or see your heart rate data with compatible gym equipment.
