Installation; Preparation; Connectors - VDO CD 4203 User Manual

INSTALLATION

If your car is fitted with fully ISO connectors,
you can directly install the car radio.
If your car's connectors comply with other
standards, contact your dealer to obtain specific
adapter cables (see figures in the installation
card) then carry out the installation yourself (see

PREPARATION).

Note : Ensure that the cables cannot be
damaged by sharp edges or moving parts.
PREPARATION
The device must be connected to a 12V DC
electrical system with a negative terminal earth
(car chassis).
Warning: Installation that does
!
not conform to these
requirements may result in
malfunction, damage or fire!
To avoid the risk of a short circuit during ins-
tallation, disconnect the negative terminal of
the battery until the set has been securely
installed and connected.
(see Installation card Fig.1).

CONNECTORS

Connector A**
(see Fig.2)
a-Power Supply
1- Brown wire A8: connect to an earthing
point on the car chassis.
2- Red wire A7: connect to a permanent 12V
supply, main power supply for the set.
Ensure that this connection can handle a
current of 10A.
3- Yellow/orange wire A4: connect to the
switched 12V supply of the ignition.
Note : The ON/OFF logic function exists only
when wire A7 (red) is connected to the

-Optional connections
Electronic or Motorised Antenna
Connect to pin A5 the power supply for an
electronic antenna or the control wire for the
relay of an automatic motorised antenna. Use
the small connector supplied.
Note 1 : Do not use this connection for direct
power supply to the antenna motor.
Note 2 : Use passive antenna with long wire:
some antennae may create waveband recep-
tion problems.
Pilot Light
When the car headlights are switched on, the
control key lighting remains on even when the
car radio is switched off.
Connect pin A6 to the dashboard wiring, using
the small connector provided.
SDVC and Speed Warning
The SDVC (Speed Dependent Volume Control)
automatically increases or decreases the volume
according to the speed of the car. The speed
limit warning can be used to indicate that you
have exceeded a given speed.
Connect pin A1 to a signal from the speedo-
meter (some cars are already prepared: e.g.
some VW and Vauxhall/Opel models). Please
contact your dealer for this point.
If not, use a more detailed installation requiring
extra equipment. This must be accomplished
by a technician who is familiar with the car
mechanical electrical systems. After connection,
refer to "Calibrating the Speed" under
CONFIGURATION in page 10.
Connector B**
This connector is used to connect the four
loudspeakers: left and right fronts, left and right
rears (see Fig.3)
Warning: Do not connect any
! loudspeaker leads to earth or
directly to a booster / amplifier
or via an external fader (unless
equipped to receive such an
high level input) !
