Using RDS

Your audio system is equipped with a Radio Data System (RDS). RDS features are available for use only on FM stations that broadcast RDS information.

With RDS, your radio can do the following:

    • Seek to stations broadcasting the selected type of programming,
    • receive announcements concerning local and national emergencies,
    • display messages from radio stations, and
    • seek to stations with traffic announcements.

This system relies upon receiving specific information from these stations and will only work when the 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.

While you are tuned to an RDS station, the station name or the call letters will appear on the display instead of the frequency. RDS stations may also provide the time of day, a program type (PTY) for current programming and the name of the program being broadcast.

RDS Messages

ALERT: Alert warns of local and national emergencies. When, an alert announcement comes on the current radio station or a related network station, ALERT will appear on the display. You will hear the announcement, even if the volume is muted or a cassette tape or compact disc is playing. 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 when the announcement has ended. You will not be able to turn off alert announcements. If the radio tunes to a related network station for the announcement, it will return to the original station when the announcement is finished. The radio uses TA volume for alert announcements. To increase or to decrease volume, turn the VOL knob. The volume can not be turned completely down or off.

TA (Traffic Announcement): If TA appears on the display, the tuned station broadcasts traffic announcements and when a traffic announcement comes on the tuned radio station you will hear it. If the current tuned station does not broadcast traffic announcements, when TA is turned on it will seek to a station that does. When the radio finds a station that broadcasts trafiic announcements, it will stop and TA will be displayed. When a traffic announcement comes on the tuned radio station you will hear it. If no station is found, No Traffic will appear on the display. Your radio will play the traffic announcement even if the volume is muted or interrupt the play of a cassette tape or CD if the last tuned station broadcasts traffic announcements. To turn TA on or off, perform the following steps:

  1. Press the TUNE/SEL knob to enter the main menu.
  2. Turn the TUNE/SEL knob until TRAFFIC ANNOUNCE appears on the display.
  3. Press the TUNE/SEL knob to select ON or OFF. An X will appear in the box when TA is selected on.
  4. Press the BACK button to exit the display. To return to the original display keep pressing the BACK button or wait for the display to time out.
MSG (Message): If the current RDS station has a message, MSG will appear on the display. If the whole message does not appear on the display, parts of the message will appear every three seconds until the message is completed. Once the completed message has been displayed, MSG will disappear from the display until another new message is received. If you would like to display the message, perform the following steps:

  1. Press the TUNE/SEL knob to enter the main menu.
  2. Turn the TUNE/SEL knob until RECALL RDS MESSAGE appears on the display.
  3. Press the TUNE/SEL knob. The message will be displayed.

Once the message has been displayed, MSG will disappear from the display until another new message is received.

Activating PTY Stations

Press the pushbutton for the PTY that you would like to listen to. Not all stations support PTYs and pressing the pushbutton may not take you to all of the stations with that music type.

AF (Alternate Frequency): Alternate frequency allows the radio to switch to a stronger station with the same program type. To turn AF on or off, perform the following steps:

  1. Press the TUNE/SEL knob to enter the main menu.
  2. Turn the TUNE/SEL knob until ALTERNATE FREQ. appears on the display.

Cassette Tape Messages

If an error occurs while trying to play a cassette tape, it could be that one of the following has occurred:

    • The cassette tape is tight and the cassette player cannot turn the hubs of the tape. Hold the cassette tape with the open end down and try turning the right hub counterclockwise with a pencil. Flip the tape over and repeat. If the hubs do not turn easily, your cassette tape may be damaged and should not be used in the player. Try a new tape to be sure your player is working properly.
    • The cassette tape is broken. Check to see if your tape is broken. Try a new tape.
CLEAN TAPE: If this message appears on the display, the cassette tape player needs to be cleaned. It will still play tapes, but you should clean it as soon as possible to prevent damage to the tapes and player. See Care of the Cassette Tape Player . If any error occurs repeatedly or if an error can't be corrected, contact your dealer. Your cassette tape player automatically reduces background noise. Dolby Noise Reduction is manufactured under a license from Dolby Laboratories Licensing Corporation. Dolby and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation. Auto CrO 2 allows the cassette tape player to adjust to the type of cassette tape for clearer sound for CrO 2 cassette tapes.
