RDS OPERATIONS

What you can do with RDS

RDS (Radio Data System) allows FM stations to
send an additional signal along with their regular
programme signals. For example, the stations send
their station names, as well as information about
what type of programme they broadcast, such as
sports or music, etc.
Another advantage of RDS function is called
"Enhanced Other Networks." By using the
Enhanced Other Networks data sent from a station,
you can tune in to a different station of a different
network broadcasting your favorite programme or
traffic announcement while listening to another
programme or to another source such as CD.
By receiving the RDS data, this unit can do the
following:
• Tracing the same programme automatically
(Network-Tracking Reception)
• Standby Reception of TA (Traffic Announcement)
or your favorite programme
• PTY (Programme Type) search
• Programme search
• And some other functions
Tracing the same programme
automatically (Network-Tracking
Reception)
When driving in an area where FM reception is not
good, the tuner built in this unit automatically tunes
in to another RDS station, broadcasting the same
programme with stronger signals. So, you can
continue to listen to the same programme in its
finest reception, no matter where you drive.
(See the illustration on the next page.)
Two types of the RDS data are used to make
Network-Tracking Reception work correctly — PI
(Programme Identification) and AF (Alternative
Frequency).
Without receiving these data correctly from the RDS
station you are listening to, Network-Tracking
Reception will not operate.
