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 Bluetooth
TM
interface in the mobile phone and sent to
the Bluetooth
TM
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 Bluetooth
TM
module and transferred via the Bluetooth
TM
antenna to the
mobile phone. The mobile phone then transmits the call via the phone antenna.
