Important information

Radio operation

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. Should the
traffic situation become particularly deman­ding, we would advise you not to use the
radio. Please keep in mind that you travel a
distance of 14 m per second at a speed of
only 50 km/h. When adjusting the volume,
make sure that you are still able to hear
sounds coming from outside of the vehicle,
so that you are always able to react to war­ning signals.

Installation / Hook-up

If you would like to install your new car radio
yourself or add other audio components to
the existing ones, then please read the enclo­sed instructions on installation and hook-up
carefully.
Do not ground the loudspeaker outputs!
Use only Blaupunkt-certified accessories and
spare parts.

With this car radio you can receive FM fre­quencies ranging from 87.5 to 108 MHz.

Station search

m should not be lit up in the display. If it is,

switch it off by pressing lo • m

•

press right or left.

press right or left quickly.
The frequency will move up or down in
short intervals.

Adjusting station search sensiti­vity for FM

You can adjust the sensitivity of the automa­tic station search.

• Press lo • m.
When “Io” is visible in the display, then
only those stations with relatively strong
signals will be picked up (low sensitivi­ty).
When “Io” is not visible in the display,
then stations with weaker signals will
also be picked up (high sensitivity).

Stereo - mono switch

If you would like to switch between stereo
and mono reception:

• Press lo • m for approximately 2 se-
conds.
During mono reception the stereo sym­bol will light up in the display.

Each time the car radio is switched on, the
reception will automatically be set to stereo.

automatically

(Travelstore)

In your reception area you can automatically
store the five nearest FM stations, sorted
according to their frequencies.
This feature is particularly useful when you
are travelling.

• Press FM•T for at least 2 seconds.
The radio will search for the nearest FM
stations and store them in the memory
bank “T” (Travelstore). When the pro­cess has been completed, the first stati­on will be set.

If you wish, you can also store stations in the
Travelstore memory bank manually.

Recalling stored stations

You can recall the stored stations by pressing
the corresponding buttons.

Press FM•T until I, II, III or T appears in
the display.

• Select the station by pressing the but­ton 1-5, press repeatedly if necessary.

Many FM stations broadcast traffic news for
their reception area at regular intervals. Sta­tions using the ARI system broadcast an “ARI
signal” during their programmes, so that your
car radio can recognize them. Another signal
is broadcast to indicate the beginning and
end of a traffic message. These traffic mes­sages are broadcast at a preset volume. If
you are playing a cassette, it will be interrup­ted until the traffic message has ended and
will then resume operation.

Switching the traffic messages (ARI) on
and off

If you want to switch the reception of traffic
messages (ARI) on or off

• Press ARI.
ARI will light up in the display, when the
reception is switched on.

Now the radio will only pick up those stations
broadcasting the ARI signal.

Warning beep

Should you leave the reception area of the
station you are tuned to, then you will hear a
warning beep after approximately 30 se­conds. If you should press a button preset for
a station which does not broadcast the ARI
signal, then you will also hear a warning
beep.

Appendix

Care of your audio equipment

We recommend that you use only C60/C90
cassette tapes in your car radio. Protect your
cassettes from dirt, dust and temperatures
exceeding 50 °C. During cold weather, allow
cold cassettes to warm up somewhat before
playing them in order to avoid uneven tape
transport. Operating problems and sound
distortions may occur after approximately
100 hours of playing time and are caused by
dust particles which adhere to the rubber
roller pad and the tape head. Use a cleaner
cassette to remove normal dirt build-up. If
more dirt than usual has accumulated, use a
cotton bud dipped in rubbing alcohol to clean
these parts. Never use any hard tools.
