- Network Tracking receiption uses the PI and AF codes. The PI code identifies the coun-
try, area and broadcast system. AF lists up which reception frequencies at the area are
broadcasting the same program and automatically changes to the best reception qua-
lity offering frequency without the need to interrupt the program by a seek function.
- Traffic programmes and announcements can be automatically received using the TA
features.
- The station name is displayed automatically when a RDS station is received.
B) AF (Alternative Frequencies / REG (Regional):
RDS AF Function
There are the following possible modes available:
- AF off: The network tracking is deactivated. Only station name will be displayed.
- AF on: Network tracking is activated. AF function changes between stations belonging
to the broadcast network being received.
(Can be adjusted within the RDS Setup menu)
Note: When this unit is set to this mode (REG OFF), a station broadcasting a different
regional program in the same network may be received at certain times. This can hap-
pen only in case of listening to regionalized programs; no malfunction!
- AF on / REG ON: Network tracking is activated. Regional mode is engaged (AF
function changes between stations broadcasting the same program at all times).
Regional mode shall be selected only in case of driving in certain local areas.
(Can be adjusted within the RDS Setup menu)
- RDS may not operate correctly in areas where no alternative station can be received.
- In reception borderland of a program chain normally no alternative stations can be
found. In this case also a high advanced RDS function cannot help anymore, another
program- of the driving area- must be selected.
- Especially in regional mode such reception borderland can be often reached. Because
of possible reduced reception quality, the regional function shall be used only for dri-
ving short distances.
