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 the radio is tuned to an RDS station, the station name or 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. For RDS, press the INFO knob to change what appears on the display while using RDS. The display options are station name, RDS station frequency, PTY, and the name of the program (if available). To change the default on the display, press the INFO knob until you see the display you want, then hold the knob until you hear a beep. The selected display will now be the default.
