Important information
What you need to know!
Beforestartingtouseyournewcarradioyou
shouldcarefullyreadthroughtheinformation
on “Traffic safety” and “Anti-theft coding”.
Traffic safety
Traffic safety has always priority. Use your
car radio in such a manner that you are
always able to cope with and react to the
prevailing traffic situation at any given time.
Remember, even at 50 km/h you are still
moving at a speed of 14 m per seconds.
It is also very important that you are able to
hear, and react to, acoustic warning signals
around you, for example from the police or
the firebrigade.
Therefore, adjust the volume reasonably.
QuickOut
Using the QuickOut handle you can easily
pullyourradiooutoftheinstallationcompart-
ment to take it along. The preset stations
remain stored for a longer time.
To take out the radio.
• press knob (a), take the handle (b) and
pull the unit out.

ACD 9431
14
To listen to the radio or cassette again,
• insert the set into the compartment until
it stops and move the handle back to
the front panel.
If the coding system is off, your set will be
ready for operation.
If the coding system is on, proceed as des-
cribed under “Restart following interruption
of power supply”.
Installation/connection
The code system can only be switched on
and off, if the radio is connected to perma-
nent power.
If you like to install your new car radio by
yourself or add other audio components to
the existing ones, then please read carefully
the enclosed instructions on installation and
connection.
Do not connect the loudspeaker outputs to
ground!
Only use the accessory and replacement
parts approved by Blaupunkt.
Anti-theft coding
The car radio comes standard with the code
system deactivated.
If the anti-theft coding system is on while the
power supply to the unit is interrupted (e.g.
theft,disconnectingthecarbattery),thesetis
electronically blocked. Then it may only be
used again after the appropriate code num-
ber has been entered (see car radio pass-
port).
Wrong code number entered
Itshouldnotbe possible forthieves to ascer-
tain the code number by trial-and-error. This
is why the set will be blocked for a certain
period of time, if an incorrect code number is
entered. In this case, “- - -” will appear in the
display.
This waiting time is 10 seconds after the first
three attempts, and 1 hour following subse-
quent attempts.
After 19 unsuccessful attempts, “OFF” will
appear in the display and the set can no
longer be restarted.
Note:
Keep you car radio passport with the code
number in a safe place in order to avoid
“unauthorized access” to your car radio.
If the power supply to the radio is interrupted
while the code system is switched on, you
need to know the right code number.
The radio will operate again as soon as you
have entered the right code number.
If you lose your radio passport and have
forgotten your code number, you will not be
able to restart the set after the power supply
hasbeeninterrupted.Inthiscase, your radio
can only be reset in our central customer
service workshop or in one of our service
agencies abroad.
