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.

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

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

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 completed
message has been displayed, INFO 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

Playing a Cassette Tape
Your tape player is built to work best with tapes that are
up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this
player. The longer side with the tape visible should face
to the right. If the ignition is on, but the radio is off,
the tape can be inserted and will begin playing. A tape
symbol is shown on the display whenever a tape is
inserted. If you hear nothing but a garbled sound, the
tape may not be in squarely. Press EJT to remove the
tape and start over.
While the tape is playing, use the VOL, FADE, BAL,
TREB, BASS, and SEEK controls just as you do for
the radio. The display will show TAPE and an arrow
showing which side of the tape is playing.
If you want to insert a tape when the ignition is off,
first press EJT or DISP.If CHK TAPE appears on the radio display, the tape
won't play because of an error.
CHK TAPE may be displayed when the tape is tight and
the player can't turn the tape hubs. Remove the tape.
Hold the tape with the open end down and try to turn
the right hub counterclockwise with a pencil. Turn the
tape over and repeat. If the hubs do not turn easily,
your tape may be damaged and should not be used
in the player. Try a new tape to make sure your player
is working properly.
CHK TAPE may be displayed when the tape is broken.
Try a new tape.
CHK TAPE may be displayed when the tape is wrapped
