 Before using Audio Stream for the first time, you need to configure it. This video shows you how to do that with a compatible Android device. Before pairing Audio Stream with your phone, download the latest version of the Audio Key 2 app and enable Bluetooth on your phone. Make sure Audio Stream is turned off by removing it from your audio processor. Open the Audio Key 2 app, press the menu in the upper left corner, and open Connectivity Options. Select Audio Stream and then Configuration. If you have one Audio Stream, select the side you wear it on. If you have an Audio Stream on each side, select both left and right. Tap Next. Then slide the Audio Stream cover completely over your audio processor. Place it next to your phone and press Next. If it fails to configure, move the audio processor closer to the phone. Slide the Audio Stream cover off and on, and press Try again. If you want to use Audio Stream on both sides, repeat the previous step with your second audio processor. Leave the first audio processor switched on during this. Next, enter a username with 7 or fewer letters. Only letters from the Latin alphabet can be used. Then tap Save. If a Bluetooth pairing request screen appears, tap Pair. Repeat this for your second Audio Stream if you have one. Once it has paired successfully, tap OK. Exit the Audio Key 2 app. Follow the instructions provided by your phone's manufacturer to connect to a Bluetooth device. Connect to Audio Stream. Audio Stream will connect automatically whenever it is switched on and your phone has Bluetooth enabled. Now you're ready to start streaming music and phone calls directly to your audio processor.
