Hi @Irish32 - are you looking to set this device up to your Fitbit account? Here is what has to happen to make that possible.
- The original owner has to open their Fitbit app and tap Account -> Alta HR -> Remove device. They also have to remove the Alta HR from their phone’s Bluetooth settings.
- Then you have to download the Fitbit app to your phone and sign in. Make sure your Alta HR is fully charged then in your app, tap Account -> Set Up a Device. Follow the instructions from there.
Here is a link to the Alta HR manual which will have more detailed instructions. That was always one of my favorite devices. Hope you get it working. Please let us know.
