Updating the firmware

You can update the firmware of your M430 yourself to keep it up to date. Firmware updates are performed to improve the functionality of your M430. They can include improvements to existing features, completely new features or bug fixes. We recommend that you update the firmware of your M430 every time a new version is available.

You won't lose any data due to the firmware update. Before the update begins, the data from your M430 is synced to the Flow web service.

With mobile device or tablet

You can update the firmware with your mobile device if you're using 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 in the M430 to a power source before starting the update to ensure 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 M430 to your computer. The firmware updates are downloaded via FlowSync.

To update the firmware:

  1. Plug your M430 to your computer.
  2. FlowSync starts syncing your data.
  3. After syncing, you are asked to update the firmware.
  4. Choose Yes. New firmware is installed (this may take up to 10 minutes), and M430 restarts. Please wait until the firmware update has been finalized before you detach the M430 from your computer.
