Radio Data System (RDS)

RDS is used by many radio stations throughout Europe. The system provides features such as Automatic frequency changing (AF)
and trigger signals for Traffic announcements (TA) and News.

Program Identification (PI Code)

The radio identifies the station currently being received by decoding the PI Code.

Program Service Name (PS Code)

The name of the radio station that appears on the display is contained in the PS Code.
Alternative Frequency (AF)
The range for FM stations is quite limited. For this reason many stations transmit on alternative frequencies in different areas. By
using the AF function, the driver can listen to such a station continuously without retuning the radio manually between the areas.
Some stations transmit different programs in different areas during some part of the day. To avoid tuning away from a locally sent
program, the AF function can be set to stay with that program by using AF LOC (local).
When traveling long distances the reception of a locally sent program may be lost. In such case, using the AF REG (regional) will
allow the radio to tune to other transmitters within that station.
When a radio search is performed the first time after activating AF, the radio creates an internal list of available stations. An
additional search will be done due to that list, which makes the search faster. The list is sorted with respect to the stations' RDS
codes and the stations may not be tuned in frequency order in an AF search.
AF Activation
To activate or deactivate AF, perform the following:
1) Push the MENU button

2) Push button

Traffic Announcement (TA) and News
This feature allows the radio to play traffic or news announcements even if the radio is in CD mode. To ensure that the message is
heard, the volume will be automatically adjusted to the highest of the three following volume levels.
 Volume level 10 .
 The present normal volume level.
 A retained TA/News volume level.
The TA/News volume is set by adjusting the volume during a TA/News announcement. The radio will retain this TA/News volume
setting.
