^ One mobile phone network is available in sufficient strength and quality
^ Mobile phone system operating error-free
^ Compatible mobile phone inserted into UPCI [UHI] cell phone holder (Universal Portable Cell Phone Interface) (A34/15), which is connected to Bluetooth module (A34/7) (comfort telephony) or Bluetooth-capable mobile phone in vehicle and authorized at the COMAND operating, display and controller unit (A40/3) (basic telephony)
^ Enabled Subscriber Identification Module (SIM) card inserted in mobile phone

General
With basic telephony, the mobile phone must be switched on or off manually via the buttons on the mobile phone.
With comfort telephony, the mobile phone is switched on automatically by a wake-up pulse from the COMAND operating, display and controller unit when the COMAND operating, display and controller unit is switched on, via an appropriate signal, or after the expiration of the mobile phone's run-on time.
The "telephone switch-on.off characteristics" function consists of the following subfunctions:
^ Switch on function sequence
^ Switch off function sequence
^ Supplemental information

The system is described using the comfort telephony as an example. Differences from the basic telephony are marked by the symbol.

Switch on function sequence
The switch-on signal from the COMAND operating, display and controller unit is transmitted to the cradle via a direct line and via the Bluetooth module.
The mobile phone is then switched on and supplied with power. If set on the mobile phone, the Personal Identification Number (PIN) is requested after the mobile phone has been switched on. The PIN inquiry is shown on the display of the COMAND operating, display and controller unit by the COMAND operating, display and controller unit and on the instrument cluster (A1) via the interior CAN.
If the mobile phone requires a PIN inquiry, the 4 to 8-digit PIN can be entered in one of the following ways:
- Telephone buttons on COMAND operating, display and controller unit
- Voice control system (VCS [SBS]), with code (512) COMAND APS with DVD changer

The control signals from the telephone buttons on the COMAND operating, display and controller unit are processed internally. The commands from the VCS are received by the hands-free system microphone (B25) and transferred to the COMAND operating, display and controller unit via a direct line. Then the COMAND operating, display and controller unit transmits the entered PIN to the Mobile Service Switching Center using the following route:
- Direct line
- Bluetooth antenna (A2/91)
- Bluetooth module
- Cradle
- Direct line
- Frequency switchover control unit (N96), with code (389) Mobile phone preinstallation with universal interface, USA/ Canada and with code (359) TELE AID emergency call system, and direct line
- Telephone antenna (A2/22)

After registering in the mobile telephone network, the name of the mobile telephone network is shown on the display of the mobile phone and on the display of the COMAND operating, display and controller unit in vehicles except code (494) USA version or code (389) Mobile phone preinstallation with universal interface, USA/ Canada.
In vehicles with code (494) USA version or code (389) Mobile phone preinstallation with universal interface, USA/Canada, the display only takes place on the screen of the mobile phone. The mobile phone signals or data are received in the following way:
- Telephone antenna
- Direct line
- Frequency switchover control unit, with code (389) Mobile phone preinstallation with universal interface, USA/Canada and with code (359) TELE AID emergency call system, and direct line
- Cradle

The display on the mobile phone's screen is forwarded internally. The display on the COMAND operating, display and controller unit is transmitted via the following route:
- Bluetooth module
- Bluetooth antenna
- Direct line
- COMAND operating, display and controller unit

With basic telephony, the mobile phone must be switched on manually via the buttons on the mobile phone. The switch-on signal is processed internally in the mobile phone. The PIN inquiry, if set on the mobile phone, is only displayed on the mobile phone's screen. The PIN is only entered via the buttons on the mobile phone. The PIN entry is transmitted to the mobile service switching center and the registration confirmation is provided via the mobile phone's antenna. The mobile phone network name is also displayed just on the mobile phone's screen. The display of the PIN, of the mobile phone network name and the signals of the buttons on the mobile phone are processed internally in the mobile phone.

Switch off function sequence
The switch-off signal from the COMAND operating, display and controller unit is transmitted to via a direct line and the cradle via the Bluetooth module. The mobile phone is then switched off and power supply interrupted. Expiration of the run-on time configured in the mobile phone takes place internally in the mobile phone.

With basic telephony, the mobile phone must be switched off manually via the buttons on the mobile phone. The switch-off signal is processed internally in the mobile phone. If the rechargeable battery of the mobile phone is empty, the mobile phone is also switched off.

By switching off the mobile phone and then subsequently removing the SIM card, the mobile phone is taken out of operation. The SIM card may only be removed after the mobile phone has been deactivated in order to prevent permanent damage to the memory chip provided on the SIM card.

Supplemental information
The PIN serves to prevent any unauthorized use of the SIM card. The SIM card is locked after the PIN has been entered incorrectly 3 times. The SIM card is enabled again by entering the personal 8- digit Personal Unblocking Key (PUK) using the buttons on the mobile phone for basic telephony and comfort telephony.
This allows entry of a new PIN number. If the PUK is entered incorrectly 10 times in succession, the SIM card can no longer be used and a new SIM card must be applied for from the service provider.
