Audio Systems: RDS: Notes

RDS is a transmit and receive system that operates in the FM waveband. The data service provides information that is broadcast inaudibly alongside the audio signal. The station name will be displayed when the RDS system is active and tuned to a broadcasting station.

If the reception quality of the tuned station deteriorates and no alternative frequency is available the tuner will start to search. If the tuner cannot find a transmitter for the same program that offers adequate reception quality, the tuner will revert to the last frequency received.

The RDS on/off mode can be user selected. To select the RDS function the left button marked - - should be depressed. The main display will show 'RDS ON' for 3 seconds. To cancel the RDS function the same button should be depressed again. The main display will show 'RDS OFF' for 3 seconds.
