You may need to update the communication mode of your Body+ due to a recent network change or simply because you'd like to alter how your scale connects to your phone and/or Wi-Fi network. Please follow the steps below to see how to do this. 

1. Open the Withings App.
2. Go to your Devices tab.
3. Scroll down to find your scale and tap Update Wi-Fi configuration.
4. Press and hold the button on the side of the scale for three seconds and then tap Next in the Withings App.
5. Select your device from the list of accessories.
6. Select your Wi-Fi in the list of Wi-Fi networks. Your scale will synchronize your measurements automatically.
   Note: You may choose to set up your scale in Bluetooth by selecting I don't have Wi-Fi, but you won't be able to use all of the scale's functions.
7. If you choose to set up the scale in Wi-Fi, please enter your password.
8. You're all set!
