General Information
For repairs or fault finding, the receiver is fitted with a test menu (see radio self-test procedure).
The radio will operate for approximately 20 minutes without the ignition being switched to the accessories position.
The radio bleeps then switches off.
Notes:
●All radios are designed to control a CD changer.
●There is a special procedure for replacing the CD changer located in the dashboard front panel.
RADIO FUNCTION
The tuner has three selection modes displayed on the screen and accessible from the radio front panel:
–manual mode (MANU),
–preset mode (PRESET),
–alphabetical mode (LIST).
CD FUNCTION
The CD player can play conventional discs and any audio tracks on a CD-ROM.
CDs can be played in order or tracks can be chosen at random.
If a CD changer is being used, random play is possible on only one of the possible 6 compact discs.
THERMAL PROTECTION
If the radio temperature is too high for it to function properly, the volume is automatically reduced (without changing
the volume shown in the display).
Should one of the speaker tracks short circuit, the supply to the amplifier will be cut off.
VOLUME CONTROL
The volume can be increased according to the vehicle speed. To activate the function, select the desired volume
adjustment curve in expert mode (press and hold the source button until you hear a bleep): SPEED 5 for maximum
increase, 0 to switch off the increase function.
