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, the radio can:

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 is always on. RDS features are only available for
use on FM stations which broadcast RDS information.
The RDS features of your radio rely upon 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.
DISP: Press this knob to change what appears on the
display while using RDS. The display options are station
name, station frequency, PTY and the name of the
program (if available). Press and hold the display knob
to set the default display of the RDS station from the
displays available.
Accessing RDS Stations:
1. Push the SEEK TYPE button or turn the P
-TYPE
LIST/AUDIO knob to display the program type list.
2. Turn knob either clockwise or counterclockwise to
select a program type. List is alphabetical. If you
select ANY TYPE your radio will seek to the first
PTY available.
3. Push SEEK TYPE button to activate search.

TRAF: Press this button to receive traffic
announcements. If the current tuned station does not
broadcast traffic announcements, the radio will seek
to a station that does. The TRAF icon will flash on the
display. When the radio finds a station that broadcasts
traffic announcements, it will stop. If no station is found,
NO TRAF will appear on the display.
Traffic Interrupt Feature: 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 tuned station does not. The TRAF icon 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 tuned radio
station, you will hear it, even if the volume is muted or
a cassette tape or compact disc is playing. The TRAF
icon and TRAFFIC will appear on the display while
the traffic announcement plays. If the cassette tape or
compact disc player was being used, the tape or compact
disc will stay in the player and resume play at the point
where it stopped.VOL: Turn this knob clockwise to increase volume when
RDS interrupts regular play. Turn it counterclockwise to
decrease volume.
INFO: If the current station has a message, the INFO
icon will appear on the 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, INFO will
disappear from the display until another new message
is received. The old message can be displayed by

received or a different station is tuned to.

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.

broadcasts, and will not work during tests of the
