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 cov-
ers 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 de-
activate the alternative frequency following.
Traffic information "TP"
The "Traffi c Program" (TP) function per-
mits automatic and temporary switching
to an FM station broadcasting traffi c in-
formation.
The radio station or the source that you
are listening to at this point is paused.
Once the traffi c information has ended,
the system switches back to the radio
station or the source that you were lis-
tening to initially.

mode "REG"
Some stations are organised in a network.
In different regions, they broadcast diffe-
rent 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 different
programme.
The "AF", "REG" and "TP"
functions can be deacti-
vated or activated via the
"TUNE" button functions
setting mode.
Press the "TP" button.
"TP" appears on the display.
If the station is compatible,
"RDS" also appears.
If the radio detects traffi c information,
"TRAF INF" appears on the display,
followed by the frequency of the broad-
casting station, then its name.
The volume is different from that of the
previous source.
Following the broadcasting of the traffi c
information, the volume returns to that
of the source prior to the interruption.
When "TP" appears on the display,
the radio stops solely at RDS stations
broadcasting traffi c information.
On long distance journeys, when the
stored station becomes weak, the ra-
dio searches fi rst for another frequen-
cy 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 re-
turns to the stored station.
The "Radio Data System" (RDS) function
on the FM waveband permits:
- access to the display of information,
such as the name of the station, ...
- tuning to the same station while trav-
elling through different regions,
- temporary tuning to traffi c 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 station following or temporary
tuning to traffi c information announce-
ments.
The RDS allows you to continue listen-
ing to the same station by means of the
alternative frequency following. How-
ever, in certain conditions, this RDS
frequency following cannot be provided
throughout the country. Radio stations
do not cover the whole country, which
explains the loss of reception of the sta-
tion during a journey.
