FM stations that broadcast RDS information.
With RDS, the radio can do the following:
Seek to stations broadcasting the selected
type of programming
Receive announcements concerning local and
national emergencies
Display messages from radio stations
This system relies upon receiving specic
information from these stations and will only work
when the information is available. In rare cases,
a radio station may broadcast incorrect information
that will cause the radio features to work
improperly. If this happens, contact the radio
station.
While the radio is tuned to an RDS station, the
station name or call letters will appear on the
display instead of the frequency. RDS stations may
also provide the time of day, a program type
(PTY) for current programming, and the name of
the program being broadcast.
