Troubleshooting M460 sync in FlowSync

If your M460 doesn’t charge properly, or if it doesn’t connect to FlowSync, it could be because the charging area on the back of the product is not clean enough. Gently wipe off any dirt. 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.

See How do I sync my Polar Device with the Polar Flow app? for detailed syncing instructions.

• If your M460 doesn’t charge properly, or if it doesn’t connect to FlowSync, remove and replug the USB cable.
• Always connect your M460 directly to your computer’s USB port. Do not connect it via USB hub, computer docking station or USB extension cable.
• Try the other USB port(s).

Be patient and wait for the sync to start.

Close FlowSync by right-clicking/secondary clicking the icon on your computer taskbar and choosing Close. Then restart FlowSync from your computer desktop icon.

Keep the USB cable plugged into Polar M460, and the cable plugged into the computer.

You can do a soft reset by pressing and holding the UP, DOWN, BACK and LIGHT buttons simultaneously for five seconds until the Polar animation is shown on the display. After the reset, the M460 automatically goes to time view.
