With RDS, your radio can do the following:

programming,
•receive announcements concerning local and
national emergencies,
•display messages from radio stations, and
•seek to stations with traffic announcements.
This system relies upon receiving specific information
from these stations and will only work when the

may broadcast incorrect information that will cause
the radio features to work improperly. If this happens,
contact the radio station.
While you are tuned to an RDS station, the station

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.
