How do I update the firmware of my Polar Unite?
Applies to: Unite
To keep your watch up to date and to get the best performance, always make sure to update the firmware whenever a new version is available. Firmware updates are performed to improve the functionality of your watch.
You won't lose any data due to the firmware update. Before the update begins, the data from your watch is synced to the Flow web service.
With phone or tablet
You can update the firmware with your phone if you're using the Polar Flow mobile app to sync your training and activity data. The app will let you know if there's an update available and will guide you through it. We recommend that you plug the watch into a power source before starting the update to ensure a flawless update operation.
The wireless firmware update may take up to 20 minutes, depending on your connection.
With computer
Whenever a new firmware version is available, FlowSync will notify you when you connect the watch to your computer. The firmware updates are downloaded via FlowSync.
To update the firmware:
- Plug your watch into your computer with the USB charging adapter that came in the box. Align the pins of the USB charging adapter with the pins on the watch and snap the adapter into place. Also make sure that you plug the USB charging adapter in the right way, i.e. the four pins on the Polar Unite USB charging adapter must face the four pins in your computer's USB port or in the USB charger.
- FlowSync starts syncing your data.
- After syncing, you are asked to update the firmware.
- Choose Yes. The New firmware is installed (this may take up to 10 minutes), and the watch restarts. Please wait until the firmware update has been finalized before you detach the watch from your computer.
Great! We’ll let you know as soon as this product is back in stock.
Success! ##
