Operating instructions
A telephone call can be established or terminated using the:
- Buttons on the mobile phone
- Telephone buttons on the COMAND controller unit
- Audio/COMAND control panel
- Multifunction steering wheel button groups
- VCS [SBS] (only for establishing call)

Establish call function sequence using mobile phone buttons
Dialing the telephone number using the buttons on the mobile phone or selecting the telephone number from the mobile phone's telephone book and pressing the "Accept call button" initiates the telephone call in hands-free mode.

The control signals of the mobile phone buttons are internally processed and forwarded via the following route to the COMAND controller unit:
- Japan electrical connector adapter cable
- Communications control unit
- Direct line

With a mobile phone operating with Bluetooth, the control signals from the buttons on the mobile phone are processed internally. They are not forwarded to the COMAND controller unit. The telephone call is completed in "Private mode" when the mobile phone supports "Private mode" "Private mode" is activated.

Establish call function sequence over phone buttons on the COMAND controller unit
Dialing the telephone number using the phone buttons on the COMAND controller unit and pressing the "Accept phone call" button establishes the telephone call in the handsfree mode. The control signals from the COMAND controller unit telephone buttons are processed internally.

Establish call function sequence over Audio/COMAND control panel
The basic telephone (ComTel) function is activated using the TEL hardkey on the COMAND controller unit or the ComTel menu item in the application bar on the Audio/COMAND display (A40/8) using the Audio/COMAND control panel and then shown on the Audio/ COMAND display. The control signals from the COMAND controller unit TEL hardkey are processed internally. The control signals from the Audio/COMAND control panel are forwarded via the telematics CAN (CAN A) to the COMAND controller unit.

The menu item is shown on the Audio/COMAND display by the COMAND controller unit via a low voltage differential signal (LVDS) line.
The user can then select a telephone number via the Audio/ COMAND control panel using one of the following options:
- Enter telephone number using available speller
- Search for telephone number using "Name" menu entry in the phone book
- Search for the telephone number using the "Address Book" menu entry in the address book
- Search for telephone number using the "Call Lists" (received or dialed) menu entry in the call lists

Activating the "SEND" function establishes the telephone call in the handsfree mode.
The control signals from the Audio/COMAND control panel are forwarded over the telematics CAN to the COMAND controller unit.

Establish call function sequence over multifunction steering wheel button groups
The address book of the COMAND controller unit or the phone book of the mobile phone is selected by pressing the system selection button (S110s3) via the selection menu in the instrument cluster (A1).
The name of the person to be called is selected by scrolling forward and back in the address book of the COMAND controller unit or the phone book of the mobile phone using the scroll forward and back button (S110s1).
The accept/terminate phone call button (S111s3) can be used to establish the telephone call in the handsfree system.

The control signals of the multifunction steering wheel button groups are forwarded over the following components to the COMAND controller unit:
- Steering LIN (LIN E1)
- Steering column module control unit (N80)
- Chassis CAN (CAN-E)
- Instrument cluster
- Interior CAN (CAN B)

The display in the instrument cluster is generated by the COMAND controller unit over the interior CAN.

Function sequence, establish call using voice control system
Pressing the voice control system ON button (S111s4) of the right multifunction steering wheel button group activates the voice control of the voice control system.
The voice control system button control signal is forwarded via the following components to the COMAND controller unit:
- Steering LIN
- Steering column tube module control unit
- Chassis CAN
- Instrument cluster
- Interior CAN

A signal tone is emitted after the voice control system has been activated.
The signal tone is output by the COMAND controller unit via direct lines at the following speakers:
- Left front door speaker (H4/1)
- Right front door speaker (H4/2)
- Left rear door speaker (H4/3)
- Right rear door speaker (H4/4)

Now different voice commands can be used to search and select a telephone number.
The voice commands are recorded by the voice control system microphone (B25/7) and forwarded via a direct line to the COMAND controller unit.
The voice control of the voice control system (VCS [SBS]) is used to establish the telephone call in the hands-free mode.
The individual voice commands are listed in the "Linguatronic operator's manual".

Function sequence, establish call for phone call in hands-free mode
After the telephone call has been established the COMAND controller unit transmits or receives the mobile phone signals or data via the following route:
- Direct line
- Communications control unit
- Direct line
- Japan electrical connector adapter cable
- Direct line
- Multifunction antenna (A28/11)

The voice input in hands-free mode is recorded by the VCS [SBS] microphone and forwarded via a direct line to the COMAND controller unit.
Voice output is performed by the COMAND controller unit via direct lines at the following speakers:
- Left front door speaker
- Right front door speaker
- Left rear door speaker
- Right rear door speaker

With a mobile phone operated with Bluetooth, the COMAND controller unit transmits or receives the mobile phone signals or data via the Bluetooth antenna (A2/91) and the mobile phone antenna, except when the telephone call is established using the mobile phone buttons. In the event of establishing a telephone call using the mobile phone buttons, the mobile phone transmits or receives the mobile phone signals or data via the mobile phone antenna. Voice input takes place using the microphone integrated in the mobile phone and voice output is emitted via the speakers integrated into the mobile phone ("private mode").

In "Private mode" the user can make a call without other passengers in the vehicle being able to participate in the conversation when the mobile phone supports "Private mode" and "Private mode" is activated.

Terminate call function sequence using mobile phone buttons
Pressing the "QUIT" button on the mobile phone terminates the telephone call. The control signals of the mobile phone buttons are internally processed and forwarded via the following route to the COMAND controller unit:
- Japan electrical connector adapter cable
- Communications control unit
- Direct line

On a mobile phone not connected to the Japan electrical connector adapter cable and operated via Bluetooth, the control signals of the mobile phone buttons are processed internally. They are not forwarded to the COMAND controller unit.

Terminate call function sequence over phone buttons on the COMAND controller unit
Pressing the "END" button on the COMAND controller unit terminates the telephone call. The control signals from the COMAND controller unit telephone buttons are processed internally.

Terminate call function sequence over Audio/COMAND control panel
When the "Reject" option is activated in the basic ComTel function on the Audio/COMAND display, the telephone call is terminated. The control signals from the Audio/COMAND control panel are forwarded over the telematics CAN to the COMAND controller unit.

Terminate call function sequence over multifunction steering wheel button groups
The accept/terminate phone call button terminates the telephone call. The control signals of the multifunction steering wheel button groups are forwarded over the following components to the COMAND controller unit:
- Steering LIN
- Steering column tube module control unit
- Chassis CAN
- Instrument cluster
- Interior CAN

Function sequence, call termination
Once the telephone call has been terminated, the COMAND controller unit interrupts transmission or reception of the mobile phone signals or data. This happens internally in the COMAND controller unit.

For a mobile phone not connected to the Japan electrical connector adapter cable and operated via Bluetooth, the COMAND controller unit interrupts the transmission or reception of mobile phone signals or data in an internal control-unit procedure, except where a call is terminated using the mobile phone buttons.
When a telephone call is terminated using the mobile phone buttons, the mobile phone interrupts the transmission or reception of mobile phone signals or data. This process runs internally in the mobile phone.
