GF82.85-P-2007FAA Telephone Mode, Function

MODEL 203.7
- with CODE (386) Mobile phone
MODEL 203.7 as of model year 09/Modification Year 08 model refinement package

Function requirements
- Status "Circuit 30 ON" or "Circuit 15R ON".
- Mobile phone system operating error-free.
- A mobile telephone network is available in sufficient strength and quality.
- Compatible mobile phone inserted into UPCI [UHI] cell phone holder (Universal Portable Cell Phone Interface) (A34/15).
- Enabled Subscriber Identification Module (SIM) card inserted into mobile phone.

The cradle is connected to the UPCI (Universal Portable Cell Phone Interface) control unit (N123/1). The UPCI control unit forms the interface to the Media Oriented Transport System (MOST).

Depending on the equipment installed one of the following control units will be installed, hereafter referred to as the "audio unit":
- Radio (A2), with code (523) MB Audio 20 radio
- Radio and navigation unit (A2/56), with code (525) MB Audio 50 APS radio
- COMAND operating, display and controller unit (A40/3), with code (527) COMAND APS with single DVD drive (with navigation)

General
The UPCI [UHI] control unit enables mobile phones from different manufacturers (e.g. Siemens, Motorola, Nokia) to be operated in the vehicle. The system installed in the vehicle is able to communicate with various mobile phones. It is only necessary to install the mobile phone cradle required for the mobile phone on the Universal Portable Cell Phone Interface contact plate.

The mobile phone's rechargeable battery is charged using the UPCI [UHI] control unit. The battery is charged automatically as soon as the UPCI [UHI] control unit is active, irrespective of whether the mobile phone is switched on or off.

The audio equipment comes with the following operating characteristics in telephone operation:
- Automatic disabling of telephone card when the personal identification number (PIN) is entered incorrectly 3 times
- Direct dialing of the telephone number via the numerical keypad, display of the name of the person called (if the number entered is known)
- Speed-dialing of the first 10 memory locations by pressing one key only or dialing all other memory locations by entering the 3-digit memory location number
- Selection from memory lists, sorted according to
- memory location numbers
- names (alphabetic)
- list of 10 last dialed numbers

- display of caller's number (if the number is also transmitted)
- display of name (if the number is known)
- SMS
- telephone book processing
- note book toggling

The telephone operation is subdivided into the following subfunctions:

- Function sequence for transmitting and receiving telephone signals, except code (228) Stationary heater
- Function sequence for transmitting and receiving telephone signals, with code (228) Stationary heater
- Function sequence for handsfree system
- Function sequence for composing and editing SMS messages

Operating instruction
The telephone system can be operated as follows:
- Buttons on the mobile phone
- Telephone buttons or keypad on the audio equipment
- Multifunction steering wheel (MFL)
- Voice control, with code (813) Voice control system (VCS [SBS])

The volume can be adjusted separately for the telephone mode.

Function sequence for transmitting and receiving telephone signals, except code (228) Stationary heater
Telephone signals are received as follows:
- Telephone antenna (A2/49a1)
- Direct line
- E-net compensator (A28/3)
- Direct line
- Cradle with mobile phone inserted
- Direct line
- UPCI [UHI] control unit
- MOST
- Audio equipment

The transmitting of the signals is done in the reverse manner, whereby the acoustic signals from the handsfree system microphone group (A67b1) are sent, as described under "Function sequence for handsfree system", to the audio equipment.

The E-net compensator is used to compensate for transmission losses caused by the higher transmission frequency of the E-net by means of amplification.

An operational telephone is shown by a symbol on the audio equipment's display and when inserted into the cradle, the phone's reception field strength is also shown.

All control signals and useful signals (e.g. tone signals when the handsfree system is activated) are transmitted over the MOST.

Function sequence for transmitting and receiving telephone signals, with code (228) Stationary heater
Telephone signals are received as follows:
- Telephone antenna
- Direct line
- Telephone/cell phone/STH radio remote control antenna splitter (A2/53)
- Direct line
- E-net compensator
- Direct line
- Cradle with mobile phone inserted
- Direct line
- UPCI [UHI] control unit
- MOST
- Audio equipment

The transmitting of the signals is done in the reverse manner, whereby the acoustic signals from the handsfree system microphone group are sent, as described under "Function sequence for handsfree system", to the audio equipment.

The E-net compensator is used to compensate for transmission losses caused by the higher transmission frequency of the E-net by means of amplification.

An operational telephone is shown by a symbol on the audio equipment's display and when inserted into the cradle the phone's reception field strength is also shown.

All control signals and useful signals (e.g. tone signals when the handsfree system is activated) are transmitted over the MOST.

Function sequence for handsfree system
The voice signals are received by the handsfree system microphone group in the mirror housing of the inside rearview mirror unit (A67) and are then routed in vehicles except code (813) Voice control system (VCS [SBS]) as follows:
- Direct line
- UPCI [UHI] control unit (digitization of signals)
- MOST
- Audio equipment

For vehicles with code (813) Voice control system (VCS [SBS]) the handsfree system microphone group of the inside rearview mirror unit signals are routed as follows:
- Direct line
- Voice control system control unit (A35/11)
- MOST
- Audio equipment
- MOST
- UPCI [UHI] control unit

Handsfree conversation is controlled by pressing the "Micro On, Micro Off" button on the audio equipment.

During a handsfree telephone call the audio source is automatically muted. Operation can only take place via the multifunction steering wheel or on the audio equipment.

Function sequence for composing and editing SMS messages
In the basic service menu the "Mail" button leads to the creation, dispatch and administration of text messages (short message service - SMS).
The following options are available:
- Call up mail inbox
- Call up mail outbox
- Call up mail draft
- Create new messages
- Configure mail settings

Characters are entered using the predictive speller or the 12-key keypad. These functions are also used for sending SMS messages; a receiver can be specified or dialed from the telephone book.

Data safety, SMS buffer
When the power supply fails, the characters stored in the buffer are saved. However, it is possible for up to 4 characters to be lost. When switched off in a controlled manner, no characters are lost.
