Using your smartphone, download the free W&H BeHear app from Google Play Store or the Apple Store. Open the W&H BeHear app, and choose an interface language. You will be prompted to indicate which headset you have (either BeHear NOW or BeHear ACCESS). The app will then show you how to put the headset into pairing mode (your phone's Bluetooth option must be active). Follow the app's on-screen prompts to connect the headset to your phone. Once the connection is successful, the headset will be turned off automatically. You are instructed to press its power button to turn it back on. Once the headset is back on, the pairing process is complete and you should start the hearing assessment.
