You can start sharing music with an intercom friend using Bluetooth stereo music during a two-way intercom conversation. When you terminate music sharing, you can go back to the intercom
conversation. To start or terminate sharing music, press and hold the Center Button for 1 second during an intercom conversation until you hear a double beep and you and your intercom friend
will listen to or terminate sharing music. To track forward or track back, press the (+) Button or the (-) Button for 1 second until you hear a mid-tone single beep.
