Using the RDS Functions
What is RDS?
RDS (radio data system) is a system for transmitting data along with FM programs. This
data, which is inaudible, provides a variety of features such as: program service name, pro-
gram type display, traffic announcement standby, automatic tuning and program type tun-
ing, intended to aid radio listeners in tuning to a desired station.
Note:
• RDS service may not be provided by all stations.
• RDS functions, like AF (alternative frequencies search) and TA (traffic announcement standby), are
only active when your radio is tuned to RDS stations.
Alternative frequency function
The AF (alternative frequencies search) function is used to search for other frequencies in
the same network as the currently tuned station. It automatically retunes the receiver to
another frequency in the network which is broadcasting a stronger signal when there are
problems with reception of the currently tuned station or better reception is possible on
a different frequency.
Note:
• AF tunes the receiver only to RDS stations when you use seek tuning or BSM auto memory with
the “AF” indicator ON.
• When you recall a preset station, the tuner may update the preset station with a new frequency from
the station’s AF list. (This is only available when using presets on the FM-1 and FM-2 bands.) No
preset number appears on the display if the RDS data for the station received differs from that for
the originally stored station.
• Sound may be temporarily interrupted by another program during an AF frequency search.
• When the tuner is tuned to a non-RDS station, the “AF” indicator flashes.
• AF can be switched ON or OFF independently for each FM band.
