First, make sure you have bluetooth on your phone turned on. Next, make sure you have the Neosensory app downloaded on your phone from the Apple App or Google Play stores. Next, turn on your Buzz and open the app. The app will walk you through step by step instruction on the pairing process with helpful visuals. 

If this is your second Buzz, remove the previous Buzz device from the app under Device Management before following the steps in the app.
