The hands-free facility is activated after pressing the send/
receive key. The incoming call is encoded (scrambled) via the
Bluetooth interface in the mobile phone and sent to the
Bluetooth aerial in the vehicle. The call is received by the ULF
control unit and output via the audio speakers.
As the vehicle features a digital full-duplex hands-free facility, it
is possible to simultaneously speak and listen to calls. An echo
compensation facility avoids feedback when speaking into the
microphone. The microphone signal is sent via an AF line to the
ULF control unit. Here, the received AF signal is scrambled in
the Bluetooth module and transferred via the Bluetooth aerial to
the mobile phone. The mobile phone transmits the call via the
GSM aerial.
