Switching RDS On and Off
Set RDS to On or Off. The following
advantages result through
activating RDS:
On the display the programme
name of the set station appears
instead of its frequency.
The infotainment system always
tunes into the best receivable
broadcasting frequency of the
set station by means of AF
(Alternative Frequency).
Depending on the station that is
received, the infotainment
system displays radio text that
can contain, for example,
information about the current
program.
Switching Regionalisation On
and Off
RDS must be activated for
regionalisation. At certain times
some RDS stations broadcast
regionally different programmes on
different frequencies.
1. Set Region to On or Off.
Only alternative frequencies (AF)
with the same regional
programmes are selected.
2. If regionalisation is switched off,
alternative frequencies of the
stations are selected without
regard to regional programmes.
RDS Scrolling Text
Some RDS stations use the lines for
indicating the name of the program
to indicate additional information.
During this process the programme
name is hidden. To block out the
display of the additional information,
set text scroll freeze to On.
DAB
The digital radio system DAB
(Digital Audio Broadcasting) is a
universal broadcast system.
DAB stations are indicated by the
programme name instead of the
broadcasting frequency.
Infotainment System
General Information
With DAB, several radio
programmes (services) can be
broadcast on a single frequency.
Besides high-quality digital audio
services, DAB is also able to
transmit programme-associated
data and a multitude of other
data services including travel
and traffic information.
As long as a given DAB receiver
can pick up the signal sent out
by a broadcasting station (even
if the signal is very weak), sound
reproduction is ensured.
There is no fading (weakening of
the sound) that is typical of AM
or FM reception; the DAB signal
is reproduced at a constant
volume.
