How do I start using Polar A300?

To start using Polar A300:

  1. Go to and download and install the FlowSync software to set up your A300.
  2. Detach the wristband. For more information, see the Get started with Polar A300 video.
  3. Plug your A300 to your computer either directly (A) or with the USB cable (B) for set up and charging the battery. Make sure the cable is right way up - the USB symbols of the device and the cable should be next to each other (B).


  4. Then we’ll walk you through setting up your A300 and signing up to the Flow web service.

    If you already have a Polar account, you don’t need to create new one. Just sign in with your existing login details when taking a new product into use.

  5. After the setup is done, you’re ready to go. Have fun!
