RDS
The Radio Data System (RDS) function on the FM waveband permits:
-

automatic retuning to alternative frequencies carrying the same


station while travelling through different regions (if the transmitters
of this station cover the area through which you are travelling),
-

temporary tuning to traffic information announcements,
-


display of the name of the station, etc...
Most FM stations use RDS.
These stations transmit non-audible data in addition to their


programmes.
The data transmitted in this way allows you access to various
functions, mainly displaying of the name of the station, temporary
tuning to traffic information announcements or automatic retuning to
alternative frequencies.
RDS allows you to continue listening to the same station automatically
by means of alternative frequencies. However, alternative frequencies
may not be provided throughout the country. Radio stations do not
cover the whole country, which explains the loss of reception of the
station during a journey. Regional mode
Some stations are organised in a network.
In different regions, they broadcast different or shared programmes
depending on the time of day.
You can follow:
-

a regional station only

,
-

the entire network, with the possibility that you will be listening
to a dif

ferent programme.

RADIO
RDS alternative frequencies
Your radio automatically checks and selects the best frequency for
the radio station to which it is tuned (if the station broadcasts on
several transmitters or frequencies).
The frequency of a radio station covers approximately 30
miles
(50
km). The change from one frequency to another explains the
loss of reception during a journey.
If the station to which you are listening does not have several
frequencies in the region in which you are currently located, you can
deactivate automatic alternative frequencies. Traffic information function
The Traf
fi c Programme (TP) function permits automatic and
temporary switching to an FM station broadcasting traffic
information.
The radio station or the source that you are listening to at this point
is paused.
Once the traffic information has ended, the system switches back to
the radio station or the source that you were listening to initially .
