Using RDS Your audio system is equipped with a Radio Data System (RDS). RDS mode gives you many useful new features. With RDS, the radio can do the following: P-TYPE: This button is used to turn on and off Program Type (PTY) selections. PTY and the light next to the button will turn on. The last selected PTY will appear on the display for five seconds. Turn the TUNE RCL P-TYPE control to select the PTY you want to listen to. Press the SEEK SCAN arrows to find radio stations for the PTY you want to listen to. The last PTY selected will be used for seek or scan modes. If a station with the selected PTY is not found, NONE FOUND will appear on the display. If both P-TYPE and TRAF are on, the radio will search for stations with traffic announcements and the selected PTY. To use the P-TYPE interrupt feature, press and hold the P-TYPE button until you hear a beep on the PTY you want to interrupt on. When you are listening to a compact disc, the last selected RDS FM station will interrupt play if that selected program type format is broadcast. AM FM: The AM FM button operates the alternate frequency feature. Alternate frequency allows the radio to switch to a stronger station with the same program type. Press and hold AM FM 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 AM FM again for two seconds to turn alternate frequency off. AF OFF will appear on the display. The radio will not switch to other stations. D Seek only to stations with the types of programs you want to listen to, D seek to stations with traffic announcements, D receive announcements concerning local and national emergencies, and D receive and display messages from radio stations. 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. 3-48
