If you are wondering how to update your tracker's firmware, just follow the steps below:
- Ensure that your tracker is near your computer. If your tracker came with a wireless sync dongle, plug the dongle into a USB port on your computer.
- Unless you installed Fitbit Connect for the first time recently, verify that you're using the latest version:
- Click the Fitbit Connect icon located near the date and time on your computer.
If you cannot find the icon, you may need to reinstall Fitbit Connect from http://www.fitbit.com/setup.
- Click Open Main Menu...
- Click Troubleshooting.
- Below the Fitbit Connect number, click Check for updates.
- Click the Fitbit Connect icon located near the date and time on your computer.
- Go back to the main menu and click Check for device update.
- When prompted, log in to your Fitbit account. Fitbit Connect will sync your tracker and then look for a firmware update. If an update is found, Fitbit Connect will display a progress bar until the update finishes. If your tracker has a screen, you'll also see a progress bar there.
- Keep your tracker close to the computer during the update, which may take several minutes. When the update is done you'll see a confirmation message and your tracker will restart. You're all set.
After this, you are all set!
