This system relies upon receiving specific 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 you are tuned to an RDS station, the station
name or the 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.
