Radio Data System (RDS)

The audio system has a Radio Data System (RDS). RDS features are available for use only on FM stations that broadcast RDS information.

With RDS, the 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
    • Seek to stations with traffic announcements

This system relies upon receiving specific information, when available, from these stations. In rare cases, a radio station can broadcast incorrect information that causes the radio features to work improperly. If this happens, contact the radio station.

While the radio is tuned to an RDS station, the station name or call letters display instead of the frequency. RDS stations can also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast.

Playing the Radio

(Power): Press to turn the system on and off.

(Volume): Turn clockwise or counterclockwise to increase or to decrease the volume.

SRCE (Source): Press to select a source, either radio or CD. The CD must be loaded to select the source and to play. CD displays if a CD is loaded. If a CD is not loaded, the display does not change from the radio source.

Finding a Station

BAND: Press to select FM1, FM2, AM, or XM1 or XM2 (if equipped).

(Tune): Turn to select radio stations.

(Seek): Press the left arrow to go to the previous station and stay there. Press the right arrow to go to the next station and stay there. The sound mutes while seeking. The radio seeks stations only with a strong signal that are in the selected band.

(Scan): Press the arrows to enter scan mode. SCAN displays. Press the arrows to scan the next station. The radio goes to a station, plays for five seconds, then goes to the next station. Press the arrows again to stop scanning. To scan preset stations, press and hold the arrows for more than two seconds until a beep sounds and PSCAN displays. The radio goes to the first preset station, plays for five seconds, then goes to the next preset station. Press the arrows again to stop scanning presets. The radio only scans stations with a strong signal that are in the selected band.

AF (Alternate Frequency): This feature lets you turn the Alternate Frequency feature on or off. See Alternate Frequency under, "Activating Program Type (PTY) Stations" later in this section for more information.

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 displays. You will hear the announcement, even if the volume is low or a CD is playing. If a CD is playing, play stops during the announcement. Alert announcements cannot be turned off. If the radio tunes to a related network station for the announcement, it returns to the original station when the announcement is finished. ALERT is not affected by tests of the emergency broadcast system. This feature is not supported by all RDS stations.

MSG (Message): If the current RDS station has a message, MSG displays. The message can display the artist, song title, call in phone numbers, etc. If the entire message does not display, parts of the message displays every three seconds until the message is complete. Once the completed message has displayed, MSG disappears from the display until another new message is received. To display the last message, perform the following steps:

  1. Press the knob to enter the main menu.
  2. Turn this knob until RECALL RDS MESSAGE displays.
  3. Press the same knob and the message displays.

Once the message displays, MSG disappears from the display until another new message is received.

TP (Traffic Program): TP displays when the radio detects a signal from an RDS station that has traffic announcement broadcast capability.

TA (Traffic Announcement): If TA displays, the tuned radio station broadcasts traffic announcements, and when a traffic announcement comes on the tuned station, you will hear it. If the station does not broadcast traffic announcements, when TA is turned on it seeks to a station that does. When a station that broadcasts traffic announcements is found, the radio stops seeking and TA displays. If no station is found that broadcasts traffic announcements, No Traffic displays. The radio plays traffic announcements if the volume is low. The radio interrupts the play of a CD if the last tuned station broadcasts traffic announcements. To turn TA on or off, perform the following steps:

  1. Press the knob to enter the main menu.
  2. Turn this knob until TRAFFIC ANNOUNCE displays.

Care of Your CDs

If playing a CD-R, the sound quality can be reduced due to CD-R quality, the method of recording, the quality of the music that has been recorded, and the way the CD-R has been handled. Handle them carefully. Store CD-R(s) in their original cases or other protective cases and away from direct sunlight and dust. The CD player scans the bottom surface of the disc. If the surface of a CD is damaged, such as cracked, broken, or scratched, the CD does not play properly or not at all. Do not touch the bottom side of a CD while handling it; this could damage the surface. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge.

If the surface of a CD is soiled, take a soft, lint free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge.

Care of Your CD Player

Do not add any label to a CD, it could get caught in the CD player. If a CD is recorded on a personal computer and a description label is needed, try labeling the top of the recorded CD with a marking pen.

The use of CD lens cleaners for CDs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD player mechanism.

Notice: If a label is added to a CD, or more than one CD is inserted into the slot at a time, or an attempt is made to play scratched or damaged CDs, the CD player could be damaged. While using the CD player, use only CDs in good condition without any label, load one CD at a time, and keep the CD player and the loading slot free of foreign materials, liquids, and debris.

CD Messages

If the CD comes out, it could be for one of the following reasons:

    • If it is very hot. When the temperature returns to normal, the CD should play.
    • If you are driving on a very rough road. When the road becomes smoother, the CD should play.
    • The CD is dirty, scratched, wet, or upside down.
    • The air is very humid. If so, wait about an hour and try again.
    • The format of the CD might not be compatible. See Using an MP3 later in this section.
    • There could have been a problem while burning the CD.
    • The label could be caught in the CD player.

If the CD is not playing correctly, for any other reason, try a known good CD.

If any error occurs repeatedly or if an error cannot be corrected, contact your dealer/retailer. If the radio displays an error message, write it down and provide it to your dealer/retailer when reporting the problem.
