DESCRIPTION AND OPERATION

Midline system radio cassette
The midline radio cassette is located in the center of the fascia and contains the radio and tape player, four clips 
(accessible through holes in the front of the unit) secure the unit.  To  remove the radio cassette unit the four clips 
must be released with a special tool. The midline system can be controlled from the fascia mounted radio cassette, 
or from remote radio control switches on the left hand side of the steering wheel.  The audio signal can be from the 
radio, cassette player or a optional CD-autochanger. A logic control circuit in the radio cassette player controls the 
operation in the various control modes.

The radio cassette has a display screen, information shown can include current status, station (radio mode) or 
cassette tape track or (optional) CD-autochanger track/disc status. Power for illumination on the radio cassette is 
supplied from the passenger compartment fusebox.  A main fuse is also located in the connector socket area on the 
back of the radio cassette.

Security code function
A combination of buttons on the radio cassette are used to input and change security codes. Security codes make the 
unit unusable if the unit is disconnected from the vehicle without deactivating the security code. The radio cassette 
has an internal memory chip that stores the information, if the power is removed from the unit the chip will activate the 
security code feature. For this reason the security code feature must be deactivated before the unit is removed or the 
vehicles battery is disconnected.

Audio functions
A rotary knob allows changes of levels or selections during the various modes of operation, this includes volume, 
bass, treble and fader.

Cassette functions
The radio cassette has buttons for the following cassette functions eject,  tape, reverse, forward, tape eject/reversal. 

Radio functions
The radio cassette has buttons for the selection of AM or FM reception. Selection of the radio station is controlled by 
the use of the multi-function buttons on the radio cassette player, the radio headphone amplifiers or the remote radio 
controls on the steering wheel.

Traffic information and news function
A traffic information button (TA/NEWS) allows traffic or news information to be selected on the FM waveband only, in 
this mode the audio output will mute when traffic or news messages are received. After the traffic or news message 
the radio, cassette tape or CD will resume play, the traffic and news information varies with the country of use and 
radio band selected.
