 You can pair audio link with any Bluetooth-enabled phone, tablet, and many other Bluetooth devices. You can also use the Audio Key app via your audio link once it is paired. To pair audio link with a Bluetooth device, first switch on Audio Link and make sure it is in standby mode. Only the status light should be active. Switch on the Bluetooth pairing mode by pressing the Mix button and the Mic button together for two seconds. The Bluetooth symbol will blink to show that audio link is ready to be paired. Make sure Bluetooth is activated on your device and search for available Bluetooth devices. Select Med-L Audio Link and start pairing. If you are asked for a security key, enter 000. When audio link and your Bluetooth device are successfully paired, the Bluetooth symbol will stop blinking and become a constant light. If no device is paired within 60 seconds, audio link will no longer be in Bluetooth pairing mode. Press the Mix button and Mic button together again for two seconds to put audio link back in Bluetooth pairing mode.
