With the Flip3 ON, press the Bluetooth briefly to enter pairing mode, while another BT source that is already connected plays on. Now two sources can take turns playing, just by pressing play on one, then the other. The one being overridden will enter pause mode. For complete Bluetooth reset, while the Flip3 is ON and paired, press and hold the Bluetooth button for more than 3 seconds. The Bluetooth button light goes out, and the connection is broken. Press the Bluetooth button again for new pairing.
