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, the 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 that
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. Push the SEEK TYPE button or turn the P
-TYPE
LIST knob to display the program type list.
2. Turn the P
-TYPE LIST 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. Push the SEEK TYPE button to activate search.

to increase volume when RDS interrupts regular play.

program (if available). Pressing and holding this knob
will activate the RDS default display.
Finding a PTY Station
P
-TYPE LIST (Program Type): Turn this knob
clockwise or counterclockwise to select the Program
Type (PTY) you want to listen to. TYPE and a PTY
will appear on the display. Press the SEEK TYPE button
and the radio will seek to the first RDS broadcaster of
the selected program type. If the radio cannot find the
desired program type, NONE will appear on the display
and the radio will return to the last station you were
listening to.BAND (Alternate Frequency): Alternate frequency
allows the radio to switch to a stronger station with
the same program type. Press and hold BAND for
two seconds to turn alternate frequency on. AF ON will
appear on the display. The radio may switch to stronger
stations. Press and hold BAND again for two seconds
to turn alternate frequency off. AF OFF will appear on
the display. The radio will not switch to other stations.
When you turn the ignition off and then on again,
the alternate frequency feature will automatically be
turned on.

RDS Messages
ALERT!: Alert warns of national or local emergencies.
You will not be able to turn off alert announcements.

announcement plays. When an alert announcement
comes on the current radio station, you will hear it, even
if the volume is muted or a cassette tape or compact disc
is playing. If the cassette tape or compact disc player is
playing, play will stop for the announcement and resume
when the announcement is finished.
This function will only work during actual emergency
broadcasts, and will not work during tests of the
emergency broadcast system. This feature is not
supported by all RDS stations.

display. These text messages are from the RDS
broadcaster to the listening public and may be general
information such as artist and song title, call in phone
numbers, etc. Press this button to see the message.
If the whole message does not appear on the display,
parts of the message will appear every three seconds
until the message is completed. To scroll through the
message at your own speed, press the INFO button
again for less than one second. A new group of words will appear on the display.
Once the complete message has been displayed, the
information symbol will disappear from the display until
another new message is received. The old message can
be displayed by pressing the INFO button until a new
message is received or a different station is tuned to.
When a message is not available from an FM station,
NO INFO will be displayed.

announcements. If the current station does not broadcast
traffic announcements, the radio will seek to a station
that does. The traffic symbol will flash on the display.

announcements, it will stop. If no station is found,
NO TRAF will appear on the display.
Your radio can be programmed to interrupt the playback
of a cassette tape, CD or FM radio by enabling the
traffic interrupt feature. Press the TRAF button once to
seek to an RDS station that supports the traffic interrupt
feature if the current station does not. The traffic symbol
will flash on the display when seeking for a station that
supports traffic interrupt. When the traffic interrupt
feature is on, TRAF will appear on the display.

When a traffic announcement comes on the current radio
station, you will hear it, even if the volume is muted or
a cassette tape or compact disc is playing. The traffic

compact disc player was being used, the tape or compact
disc will stay in the player and resume play at the point
