RECEIVING RDS STATIONS

Radio Data System (RDS) is a data transmission system gradually being introduced by FM stations in many countries. Stations using this system transmit an inaudible stream of data in addition to the normal radio signal.

RDS data contains various information such as PI (Program Identification), PS (Program Service name), PTY (Program Type), RT (Radio Text), CT (Clock Time), EON (Enhanced Other Networks), etc.

The RDS function is used by network stations.

DESCRIPTION OF RDS DATA

This unit can receive PI, PS, PTY, RT, CT, and EON data when receiving RDS broadcast stations.

English

PS (Program Service name) mode:

The name of the RDS station being received is displayed.

PTY (Program Type) mode:

The type of program on the RDS station being received is displayed. There are 15 program types to classify RDS stations. You can make this unit search for a station which is broadcasting a program of the desired type. See page 34 for details.

RT (Radio Text) mode:

Information about the program (such as the title of a song, name of the singer, etc.) on the RDS station being received is displayed by a maximum of 64 alphanumeric characters, including the umlaut sign. If other characters are used for RT data, they are displayed with under-bars.

CT (Clock Time) mode:

The current time is displayed and updated every minute. If the data is accidentally cut off, “CT WAIT” may appear.

EON (Enhanced Other Networks):

See page 35.

CHANGING THE RDS MODE

When an RDS station is being received, PS, PTY, RT and/or CT that correspond to the RDS data services employed by the station light up on the display. By pressing RDS MODE, you can change the display mode among the RDS modes employed by the received station in the order shown below. Illumination of the RDS modes indicator shows that the corresponding RDS mode has been selected.

*When an RDS station is being received, do not press RDS MODE until one or more names of RDS modes light up on the display. If the button is pressed before one or more names light up on the display, the mode cannot be changed. This is because the unit has not yet received all of the RDS data on the station.

*If no RDS mode lights up on the display, the mode cannot be changed.

*An RDS mode not employed by the station cannot be selected.

Notes

The RDS data service cannot be utilized by this unit if the received signal is not strong enough. In particular, the RT mode requires a large amount of data to be received, so it is possible that the RT mode cannot be displayed even if other RDS modes (PS, PTY, etc.) are displayed.

There may be a case that RDS data reception is not possible due to poor reception conditions. If so, press TUNING MODE so that the “AUTO TUNING” indicator goes off from the display. Although the reception mode is changed to monaural by this operation, when you change the display to RDS mode, RDS data may be displayed.

If the signal strength is weakened by external interference during the reception of an RDS station, the RDS data service may be cut off suddenly and “...WAIT” will appear on the display.
