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

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 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.

• Make sure the USB connector is firmly in place.
• Remove and replug the USB cable into your Polar A370.
• If your Polar 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.

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.

Keep your A370 connected to the computer.
