Information about
RDS stations
When storing RDS stations you should
press the corresponding station button
only when the station name appears in
the display. This ensures that all RDS
information has been interpreted and
stored automatically.
When calling up stored RDS stations,
the corresponding station name is display-
ed. If the stored frequency is too weak for
good reception, the radio searches auto-
matically for an appropriate alternative fre-
quency (best station function).
If non of the stored alternative frequencies
is strong enough for good reception, the
desired station cannot be received at the
moment. In this case, tune to another sta-
tion.
Please make sure that the station

name is displayed when the station
is stored. If a moving text should be
displayed, this will be stored
instead of the station name.

How does RDS work?
In many European countries, RDS is al-
ready transmitted by many radio stations.
The goal is to provide an overall coverage.
With this system, an inaudible digitized
data current is transmitted in addition to
the normal FM radio signal, providing the
RDS receiver with information in encoded
form which controls, among other things,
the following functions:
• Programme identification
(PI code)
With the help of the PI code, the radio
recognizes the currently received station.
• Programme service name
(PS code)
The PS code transmits the station name
which is shown in the display.
• Alternative frequencies
(AF code)
Because of the limited transmission range
of the FM waves, the programme of one
radio provider is transmitted by several
stations on different frequencies. The AF
code informs the radio about all alternative
frequencies of the same programme.
This enables the radio to tune to the fre-
quency which can be received in the best
quality.
Tuning to another frequency is carried out
in an inaudible way.
The station name in the display remains
unchanged.
While you are driving, the RDS radio sear-
ches permanently for alternative frequen-
cies of the station selected and tunes to
this in an automatic and inaudible way.
• Traffic programme identification
(TP code = Traffic programme)
This information tells the radio that it is
currently receiving a traffic programme
station.
