Polar A360/A370 sync doesn’t start in FlowSync. What can I do?

If FlowSync doesn’t start syncing your A360/A370, try these tips:

Make sure the USB connector is dry and clean

If your product doesn’t charge properly, or if it doesn’t connect to FlowSync, it could be because the USB connector of the product is moist or isn’t dry or clean enough.
When you connect your A360/A370 to a computer, check that there is no moisture, hair, dust or dirt on the USB connector. Gently wipe off any dirt or moisture. Don't use any sharp tools for cleaning to avoid scratching. Do NOT use alcohol, cleaning chemicals, or any abrasive material such as steel wool.

Check that the USB cable works.

  • Make sure the USB connector is firmly in place.
  • Remove and replug the USB cable into your Polar A360/A370.
  • If your Polar A360/A370 plugged into your computer via USB Hub, try plugging it in directly to the computer's own USB port.
  • Try the other USB port(s).
  • Try syncing with another micro-USB cable if you have one.

Restart FlowSync

Close FlowSync by right-clicking/secondary clicking the icon on your computer taskbar/menubar. Choose Close. Then restart FlowSync from your computer desktop icon/Applications folder.

Restart your computer

Keep your A360/A370 connected to the computer.
