4. Once paired, audio from your device will stream wirelessly to the M10 and then to your connected audio system.
5. Dual Smartphone Connection: In RX mode, the M10 can connect to two smartphones simultaneously. After connecting the first phone, enable Bluetooth on the second phone and connect to "M10". The M10 will prioritize audio from the device that is actively playing.
