Radio Data System; Traffic Information - Alfa Romeo 156 Sound System Manual

Presetting FM stations
volume level
Should there be too much difference be-
tween FM station volume and tape player
volume, FM signal level can be properly ad-
justed to lower it.
Proceed as follows:
– Keep button "ON" (23) pressed for
3 seconds at least.
– Press button "1" (21) to select one of
two available levels (high, low). The display
will show "FM-LV HI" or "FM-LV
LOW".
– Press briefly button "ON" (23) to quit.
RDS function

(Radio Data System)

The radio is always ready to receive sta-
tions in the RDS mode. The display will
show the RDS station name and wording
"RDS".
To turn the RDS function on/off, proceed
as follows:
– select F1, F2 or FA
– keep button "RDS" (11) pressed un-
til "RDS" wording appears/disappears.
Selecting alternative
frequency search
Within the RDS system the radio can
work in two different modes:
– AF ON: alternative frequency search
on
– AF OFF: alternative frequency search
off.
When the signal of the RDS station tuned
weakens, the following cases may occur:
– With AF ON the RDS system activates
automatic tuning of the optimum frequency
of the station chosen, with the stations en-
abled, therefore the radio is automatically
tuned to the station with the strongest sig-
nal that is broadcasting the same pro-
gramme. During the journey it will thus be
possible to continue listening to the station
chosen without having to change the fre-
quency when changing area. Of course, the
station being listened to must be receivable
in the area the car is crossing.
– With AF OFF the radio will not tune
the strongest station automatically and it
will have to be found manually using the
tuner buttons.
To set the required mode, proceed as fol-
lows:
– Keep button "ON" (23) pressed for
3 seconds at least.
– Press button "3" (19) to select the
required mode. The display will show "AF
ON" or "AF OFF".
– Press briefly button "ON" (23) to quit.
WARNING In both modes, when lis-
tening to a RDS station, if you keep button
"TUNE" (9) pressed until the display
shows "AF SEEK", the station with the
strongest signal that is broadcasting the
same programme will be sought automati-
cally.
TI function

(Traffic Information)

Certain stations in the FM band (FM1),
FM2 and FA) are enabled to also broad-
cast information about traffic conditions. In
this case the display shows the wording
"TP".
