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

access to the display of information, such as the name of the
station, ...
-


listening to the same station while travelling through dif
ferent
regions,
-

temporary tuning to traffic information announcements.
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, automatic
retuning to alternative frequencies or temporary retuning to traffic
information announcements.
RDS allows you to continue listening to the same station by means
of alternative frequencies that carry the same station. However, in
certain conditions, RDS 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. "AF" 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
temporary 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 alternative frequencies.
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.
REG regional mode
On long distance journeys, when the stored station becomes weak,
the radio searches first for another frequency for the same station
(AF). Then, if this fails, it searches for a frequency broadcasting the
regional programme (REG). If this also fails, the radio returns to the
stored station.

Press the SEL knob repeatedly to

"TP" traffic information
The "Traffic 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 put on hold.
Once the traffic information has ended, the system switches back to
the radio station or the source that you were listening to initially.
Press the TP button.
"TP" appears in the screen. If the
station is compatible, "RDS" also
appears.
If the radio detects traffic information, "TRAF INF" appears on the
display, followed by the frequency of the broadcasting station, then
its name.
The volume is different from that of the previous source.
Following the broadcasting of the traffic information, the volume
returns to that of the source prior to the interruption.
When "TP" appears in the screen, the radio stops only at RDS
stations broadcasting traffic information. "ALERT" emergency broadcasts
An emergency broadcast automatically and temporarily interrupts
the FM station or the source that you are listening to.
The message "ALERT" appears in the screen and the volume is
different from that of the previous source.
Following the emergency broadcast, the message disappears and
the volume returns to that of the source prior to the interruption.
