Using RDS
Your audio system is equipped with a Radio Data
System (RDS). RDS is a system that receives data along
with the audio of the FM station you are currently tuned
to. You can use RDS to display program information
and to control your radio. With RDS your radio can do
the following:

Seek only to stations with the types of programs you
want to listen to,

seek to stations with traffic announcements,

receive announcements concerning local and
national emergencies, and

receive and display messages from radio stations.RDS features are only available on FM stations which
broadcast RDS information. The RDS features of your
radio rely on receiving specific RDS information from
these stations. These features will only work when the
RDS 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.
When you are tuned to an RDS station, the station name
will appear on the display, instead of the frequency.
Most RDS stations provide their station name, the time
of day and a Program Type (PTY) for their current
programming. Some stations also provide the name of
the current program.
Finding RDS Stations
To find RDS stations, perform the following steps:
1. Press the SEEK TYPE button or turn the P
-TYPE
LIST knob to display the program type list.
2. Turn the knob either clockwise or counterclockwise
to select a program type. The list is alphabetical. If
you select ANY TYPE your radio will seek to the
first PTY available.
3. Press the SEEK TYPE button to activate search.
