Description of the equipment

Audio system RD4

Radio functions

The Audio RD4 audio system has the following main radio functions

RDS (Radio Data System)

The RDS function (on the FM waveband) enables the user to continue listening to the same station regardless of the frequency used by the station in the current location; The radio continuously searches for the transmitter which transmits the same programme with the best reception

REG (REGion)

When they are organised in a network, some stations transmit regional programmes in the different regions which they serve; the regional tracking mode REG enables the user to choose to listen to the same programme

TA (Traffic Announce)

The TA function allows the user to receive traffic information

This function automatically and temporarily switches to an FM station which is broadcasting this information (this station should manage the TA)

This function is operational even while the user is listening to a source other than the radio (CD, CDC, navigation, etc.)

PTY (Program TYpe)

The PTY function enables the user to give priority to a type of programme selected from a list of 15 available programme types (the radio automatically searches for stations which correspond to the programme selected)

Radio-text

In tuner mode, the audio system searches for information (advertisement, title of a song and artist, etc) transmitted by the radio station and displays it on the multifunction screen

CD text

In CD player mode, the audio system searches for specific recorded information on the CD (the song, the artist, the title, etc.) and displays it on the multifunction screen

Radio control under the steering wheel

Radio antenna

The aerial system is the primary component of a radio reception system

The aerial system converts a radiated electromagnetic wave into an electrical and magnetic transverse wave guided by a radio aerial cable to the radio tuner

An aerial system is divided into the following components

• A wave collector suited to the type of signals to be received
• A connection cable intended to guarantee the passage of the signals between the wave collector and the aerial adaptor
• An aerial adaptor which transmits the signals received by the wave collector to the audio system cable

The AM/FM aerial permits reception of the audible radio broadcast transmissions in amplitude modulation and frequency modulation inside the vehicle

The AM/FM wave collector is located on the roof of the vehicle

The supply is provided via the core of the coaxial cable

Compact disc changer

(5) compact disc changer

The 5 CD changer is located in the centre of the fascia, below the audio system

The CD changer has 5 buttons on its front panel; each of these buttons corresponds to one of the 5 CD slots

The buttons are lit by dual colour indicator lamps (Green / orange)

The CD changer permits the playing of writeable CDs (CD-R) and rewriteable CDs CD-RW, provided they contain audio tracks (the MP3 format is not recognised by the changer)

The switch to play mode is obtained by changing the source to the CD changer from the audio system control panel or the audio control at the steering wheel

Bluetooth hands-free kit
