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: D receive announcements concerning local and national emergencies and D 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.
