Important notes

Anti-theft coding

What you really have to read

Before you operate your new car radio, plea­se read the information on “Traffic safety”
and “Anti-theft coding” carefully.

Traffic safety

As the driver of a motor vehicle, it is your
responsibility to pay attention to the traffic
situation at all times. Never use your car radio
in a way that could distract you.
Please keep in mind that you travel a di­stance of 14 m per second at a speed of only
50 km/h.
Should the traffic situation become particu­larly demanding, we advise you not to use the
radio.
Always make sure that you are still able to
hear any warning signals coming from outsi­de of the vehicle, such as police or fire engine
sirens, so that you can react accordingly.
Always select a moderate volume for playing
your car radio while you are driving.

Installation/Connection

If you would like to install this equipment
yourself or add any new components, then
please read the enclosed installation and
connection instructions carefully.
Do not connect the loudspeaker outputs to
ground!
Use only the accessory and replacement
parts approved by Blaupunkt.

This car radio is supplied with inactive code
protection. In order to switch the anti-theft
coding system on, proceed as described in
the following.
If the code protection system is active while
the power supply to the system is interrupted
(e.g. theft, disconnection of the car battery),
the set will be electronically blocked. In such
a case it can only be made operable again by
entering the correct code number given in the
car radio passport.

Entry of a wrong code number

It should not be possible for a thief to find out
the correct code number by a simple trial­and-error operation. This is why the set will
be blocked for a certain period of time after a
wrong code number was entered. The dis­play will then show “- - - -”.
The waiting time is 10 seconds after the first
three attempts and one hour following subse­quent trials.
After 19 unsuccessful attempts the display
will show “OFF”, making it impossible for you
to restart the unit.

Note:

Keep your car radio passport including the
code number in a safe place in order to avoid
“unauthorised access” to your car radio.
If the power supply to the unit is interrupted
while the code system is switched on, you
need to know the right code number.
The radio will function again as soon as you
have entered the correct code.
If you have lost your radio passport and
forgotten the code number, your radio can
only be made operable again by one of our
authorised customer service workshops,
which is subject to payment.

Switching the code system on

To activate the code system:

• Turn off the radio.

• Press preset buttons 1 and 4 simulta-

neously, hold down and

• turn the set back on again.
The display briefly shows “CODE” befo-

re the set is switched on.

• Release presets 1 and 4.

Now the code system is activated.
In future, “CODE” will always be briefly dis­played each time the radio is turned on.

Restart following an interruption
of the power supply

(code system is activated)

• Turn on the radio.
The display shows “CODE”.

• Briefly press preset button 1, the dis-
play shows “0000”.

• Enter the code number given in the car
radio passport:

Example: The code number is 2521.

- Press preset button 1 twice; the dis-

play shows “2000”.

- Press preset button 2 five times; the

display shows “2500”.

- Press preset button 3 twice; the dis-

play shows “2420”.

- Press preset button 4 once; the dis-

play shows “2521”.

• To confirm the code number:
Press the rocker button

Now your car radio is ready for operation.
However, if the display again shows four

dashes, you have made a mistake. In this
case go ahead entering the correct code
number after the waiting period has elapsed
(“CODE” in the display).

.

When turning the radio off during the waiting
time, this period is reset and will start anew as
soon as the unit is switched on again.

Switching the code system off

• Turn off the radio.

• Press preset buttons 1 and 4 simulta-

neously, hold down and

• turn the set back on again.
The display shows “CODE”.

• Now enter the code number of the car
radio passport and confirm (see ex­ample under “Restart ...”.

The code system is switched off.

Switching the code-LED on/off

When the car is stationary, you may let the
LED below the display flash for additional
theft protection.
Condition: The function is switched on (“LED
ON”)
To switch on/off (radio turned on, no CD
inserted):

• Press

Radio operation with RDS (Radio Data System)

The last adjustment will be stored automati­cally.
If the setting remains unchanged within 8
seconds, the display will switch back to the
previous condition.

On FM, the Radio Data System offers you
more convenience when listening to the ra­dio.
More and more radio stations have begun to
broadcast RDS information alongside their
programs.
As soon as a program has been identified,
the station name including a regional identi­fier, if applicable, will appear in the display,
for example, NDR1 NDS (regional program
in Lower Saxony, Germany).
When RDS is activated, the station buttons
become program buttons. You now know
exactly which program you have tuned into,
making it easy to find the desired station
quickly.
But RDS offers you further advantages:

AF - Alternative frequency

The AF (Alternative Frequency) function
makes sure that the strongest frequency of
the currently selected program is always
tuned in automatically.
This function is activated when “AF” appears
in the display.
In order to switch this function on or off,

• press the AF button briefly.
While the radio is searching for the strongest

reception signal, it will switch to mute briefly.
When “SEARCH” appears in the display after

the radio has been switched on or one of the
stored frequencies recalled, the radio is auto­matically searching for an alternative fre­quency.
“SEARCH” will disappear from the display
when the alternative frequency has been
found or the complete frequency range has
been run through.
If the reception quality of the selected pro­gram becomes too bad,

• tune into another station.

REG - regional program

Certain radio programs are split up at times
into regional programs offering local informa­tion. The 1st program broadcast by NDR, for
example, offers programs with different con­tents in the northern states of Germany
Schleswig-Holstein, Hamburg and Lower
Saxony at certain times of the day. If you are
listening to one program and move to an area
where another linked regional program beco­mes stronger, the unit will switch to that
program.
If you wish to continue listening to the first
station,

• press the AF button for approximately 2
seconds. “REG ON” appears in the
display.

If REG ON is activated, “REG ON” will appear
in the display briefly each time the radio is

You can alter the sensitivity of the automatic
station search.
For this purpose:

• Press the lo button briefly.

strong nearby stations (low sensitivity).

up less powerful stations (higher sensitivity)

Separate adjustment of the sensitivity
levels for local and distant reception

The sensitivity levels for local and distant
reception can be adjusted separately:

a) Local reception

• Press the MIX / lo button to switch
to “lo” (lights up in the display).

• Keep MIX / lo depressed until “S­LO” and the adjusted value are dis­played (follows after “MONO OFF”
or “MONO ON”).

Use the buttons to alter the sensitivity
value (“1” corresponds to high sensitivity, “3”
corresponds to low sensitivity).
The last adjustment will be stored automati­cally.
If the setting remains unchanged within 8
seconds, the display will switch back to the
previous condition.
Press MIX / lo to switch back immediately.

b) Distant reception

• Press the MIX / lo button to switch
to “dx” (“lo” disappears from the
display).

• Keep MIX / lo depressed until “S­DX” appears in the display. The
adjustment is made as described
under “a) Local reception”.

Switching from stereo to mono

quality by switching to mono:
