Radio operation with ADA and RDS

identifier, if applicable, will appear in the
display, for example “NDR1 NDS” (local ra-
dio program of Lower Saxony, Germany).
With RDS, the preset buttons become pro-
gram buttons. Now you know exactly which
program you have tuned into and in future
you can select this program directly.
But RDS even offers you more advantages:

AF - Alternative Frequency

The AF function makes sure that the radio will
always tune into the optimum frequency for
the RDS station you are listening to.
This function is activated if “AF” lights up in
the display.
In order to switch AF on/off:

Press the AF button briefly.

During seek tuning for the frequency offering
the best reception of the selected program,
the radio will be muted briefly.
When “SEARCH” appears in the display after
the radio has been switched on or one of the
stored frequencies retrieved, then the radio
is automatically searching for an alternative
frequency.
“SEARCH” goes out as soon as the system
has found an alternative frequency or after
the frequency band has been run through
completely.

Selecting the operating
mode

With the SRC (source) button you can select
between the following modes:

radio,

tape,

CD changer (option), or

operation of another audio component
connected.

To select one of the operating modes, it is of
course necessary that the corresponding
system is available, i.e. the add-on compo-
nent must be adequately connected and the
sound carrier (cassette, disc, changer maga-
zine) inserted.
To switch over to the next operating mode
available,

press the SRC button.

ADA

This car radio features ADA (Auto Directio-
nal Antenna).
The 2-fold ADA system developed by Blau-
punkt incorporates two tuners (Codem IV
concept) and sets new standards in recepti-
on quality, which is clearly superior to other
systems.
With ADA, the set simultaneously analyses
and processes the signals furnished by two
antennas. Compared to traditional concepts,
this leads to a considerable improvement in
the radio reception quality.
Also, multipath interference effects (produ-
ced by hills or buildings) are minimised to an
extent unparalleled so far.

ADA on/off - antenna test
You can switch off ADA and test the anten-
nas. For more information, read through
chapter “DSC programming, ADA”.

RDS (Radio Data System)

The Radio Data System offers you more
convenience when listening to FM.
More and more radio stations have begun to
broadcast additional RDS information a-
longside their programs.
As soon as a radio program has been identi-
fied, the station name including a regional
