Conducting a Call

If the call is accepted by pressing the send/receive key on the Radio (5 series and X5 SAV), Display Screen, steering wheel or center console, it will be conducted via the hands free microphone and vehicle speakers.

If a call is accepted by pressing the send/receive key on the mobile phone, the reaction will depend on the type of handset. In the majority of cases, however, the question appears:

"Do you wish to use the mobile phone?"

Please refer to the operating instructions of the mobile phone for a detailed description of the operating procedure of the phone.

The hands-free function is activated after pressing the send/receive key. The incoming call is encoded (scrambled) via the BluetoothTM interface in the mobile phone and sent to the BluetoothTM antenna in the vehicle. The call is received by the ULF control module and output via the radio to the audio speakers.

Since the ULF system provides a digital full-duplex hands-free operation, it is possible to simultaneously speak and listen to calls. An echo cancellation function prevents feedback when speaking into the microphone. The microphone audio signal is sent via a hardwire connection to the ULF control module. In the ULF module the received audio signal is scrambled via the BluetoothTM module and transferred via the BluetoothTM antenna to the mobile phone. The mobile phone then transmits the call via the phone antenna.
