This video tutorial will help you get started with your Polar A370 using the Polar Flow web service. Start by opening your computer’s internet browser and go to flow.polar.com/start Download Polar FlowSync and run the installer. FlowSync syncs your settings and transfers training data between your A370 and the Flow web service. Once the installation is complete, FlowSync opens automatically and asks you to connect your Polar product via cable. Plug your A370 into a powered USB port with the custom USB cable that came in the box. If the battery is completely empty, it takes a couple of minutes for the charging to start. Let your computer install any suggested USB drivers. Keep charging your A370 during the setup. The Polar Flow web service will open automatically on your internet browser. Create a Polar account or sign in if you already have one. Define the settings for your A370. The more precise you are with your settings, the more accurate and personal activity and training data you get. We recommend wearing the Polar A370 on your non-dominant hand to get the most accurate activity tracking. Next, fill in your physical information. Enter the details precisely as they have an effect on calorie calculation and other Smart Coaching features. When you’re finished, FlowSync starts syncing. Wait until the syncing is completed before unplugging your Polar A370. FlowSync makes sure that your A370 stays up to date. To enjoy A370 at its best, please update the firmware whenever FlowSync offers a new version. A firmware update may take up to 10 minutes. The firmware update can also be done via the Polar Flow app on your phone. Get the complete Polar experience by downloading and pairing your Polar device to the Polar Flow mobile application. With the Polar Flow app you’ll have an instant access to your training and activity data anywhere at any time. The Flow app and Flow web service automatically sync exercises and changed settings with each other.
