To use it:

1. Wear your sensor.
2. Open Polar Beat app on mobile you have paired your sensor with.
3. Select your sport profile, tap three dots on the top right corner, Save HR with sensor and Start
4. After your training session, you can stop the recording either by tapping the stop button on display or removing the connector from its strap.

When you come back into the Bluetooth range of your mobile, Beat will automatically offer to download your finished training session from the sensor memory and sync your Flow diary. If you have removed the connector from the strap. attach the it back to its strap and wear the sensor around your chest to ensure successful connection to Beat and smooth data transter.
