Using RDS
Your audio system is equipped with a Radio Data
System (RDS). RDS is a system that sends 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.

3-28
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, please 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.
TUNE DISP: Press this control to change what appears
on the display while using RDS. Pressing this control
will also display an RDS station frequency or program
type when the radio is on. The display options are
station name, station frequency, PTY and the name of
the program (if available). Pressing and holding this
control will activate the RDS default display.Accessing RDS
To access RDS stations perform the following steps:
1. Push the SEEK TYPE button or turn the P
-TYPE
LIST AUDIO control to display the program
type list.
2. Turn the control 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. Push the SEEK TYPE button to activate search.
VOL PWR: Turn this control clockwise to increase
volume when RDS interrupts regular play. Turn it
counterclockwise to decrease volume.
P
-TYPE LIST AUDIO: Turn this control clockwise
or counterclockwise to select the Program Type (PTY)
you want to listen to. TYPE and a PTY will appear on
