Component Identification:

The Universal Portable CTEL Interface (UPCI [UHI]) control unit allows portable CTELs (N123/1) from different manufacturers (e.g. Siemens, Motorola, Nokia) to be operated in the vehicle. It is only necessary to install the UPCI [UHI] portable CTEL holder (Universal Handy Interface) (A34/15) required for the respective portable CTEL on the Universal Portable CTEL Interface contact plate.

Telephone operation
The telephone system can be operated as follows:
^ Via the buttons on the radio (A2)
^ Using the multifunction steering wheel (MFL) in combination with the multifunction display of the instrument cluster (A1)
^ Over the voice control system (VCS [SBS]) (with code (813) Voice control system (VCS [SBS]))

Information can be displayed via the
^ Portable CTEL display
^ Multifunction display of instrument cluster (A1)
^ Display of radio (A2)

The volume can be adjusted separately for the telephone mode.

Following a request over the radio (A2), the cell phone signals are sent and received over the telephone antenna (A2/22 or A2/49a1). The signals are transmitted over the E-net compensator (A28/3) to the Universal Portable CTEL Interface (UPCI [UHI]) control unit (N123/1). The E-net compensator (A28/3) compensates for losses caused by the higher transmission frequency of the E-net by means of amplification.

The telephone is illustrated by a symbol, if it is operational, in the display of the radio (A2). Similarly, the reception field strength is displayed after insertion of the portable CTEL into the UPCI [UHI] portable CTEL holder (Universal Handy Interface) (A34/15). All control signals and useful signals (e.g. sound signals with hands- free system activated) are transmitted via the media-oriented system transport (MOST).
The portable CTEL rechargeable battery is charged over the Universal Portable CTEL Interface (UPCI [UHI]) control unit (N123/1). The rechargeable battery is charged automatically as soon as the Universal Portable CTEL Interface (UPCI [UHI]) control unit (N123/1) is activated, irrespective of whether the portable CTEL is switched on or off.

The radio (A2) has the following telephone functions:
^ 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
^ Display of caller's number for an incoming call (if number is transmitted)
^ Display of name (where telephone number is known)
^ Read text messages
^ Edit telephone book
^ Edit note book
^ Select from memory list using
- Memory location numbers
- Names (alphabetic)
- List of last 10 numbers dialed

Hands-free mode
During a phone call, the user can hold the conversation using the hands-free system. For this purpose, the hands-free system microphone group (A67b1) is located in the mirror housing of the inside rearview mirror unit. From there the microphone signals are forwarded directly to the Universal Portable CTEL Interface (UPCI [UHI]) control unit (N123/1), digitized, and sent over the Media Oriented System Transport (MOST) to the radio (A2). The signals are processed again in the radio (A2) and sent to the vehicle speakers. Hands-free operation is controlled by pressing the buttons on the control panel of the radio (A2). During a hands-free telephone call the audio source is automatically muted. Operation is possible using the portable CTEL, the MFL or the radio (A2).

Because of legal restrictions prohibiting the use of a telephone without a hands-free system while driving, it is not possible to telephone hands-free when the portable CTEL is removed from the UPCI (Universal Portable CTEL Interface) holder (A34/15).

Writing and editing text 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 possibilities exist:
^ Call up inbox
^ Call up outbox
^ Call up drafts box
^ Create new messages
^ Select mail settings

Characters are entered with the predictive speller of the portable CTEL or using the 12-key keypad of the radio (A2). These functions are also used for sending SMS messages; a receiver can be specified or dialed from the telephone book.

Data safety, SMS memory
If the battery voltage drops below 9.5 V, the characters that are present in the memory of the radio (A2) are retained. However, it is possible for up to 4 characters to be lost. When switched off in a normal manner, no characters are lost.
