Radio Data System (RDS) is a data transmission system 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 carried out
among the network stations.
Description of RDS Data
This unit can receive PI, PS, PTY, RT, CT, and EON data
when receiving RDS broadcasting stations.
I PS (Program Service name) mode:
The name of the RDS station being received is displayed.
I PTY (Program Type) mode:
The program type 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. Refer to "PTY
SEEK Function" for details.
I RT (Radio Text) mode:
Information about the program (such as the title of the song,
name of the singer, etc.) on the RDS station being received
is displayed by a maximum of 64 alphanumeric characters,
including the umlaut symbol. If other characters are used for
RT data, they are displayed with under-bars.
I CT (Clock Time) mode:
The current time is displayed and updated every minute. If
the data are accidentally cut off, "CT WAIT" may appear.
I EON (Enhanced Other Networks):
Refer to "EON Function" on page 33.
RECEIVING RDS STATIONS
Changing the RDS Mode
The four modes are available in this unit for displaying RDS
data. When an RDS station is being received, PS, PTY, RT
and/or CT that correspond to the RDS data services offered
by the station light up on the display. Press RDS MODE/
FREQ repeatedly to change the display mode among the
RDS data offered by the transmitting station in the order
shown below. Illumination of the red indicator next to the
RDS mode indicator shows that the corresponding RDS
mode is now selected.
Notes
• When an RDS station is being received, do not press RDS
MODE/FREQ until one or more RDS mode indicators light up on
the display. If you press the button before the indicators 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.
• RDS data not offered by the station cannot be selected.
• 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 may not be displayed even if other RDS modes
(PS, PTY, etc.) are displayed.
• RDS data cannot sometimes be received under poor reception
conditions. If so, press TUNING MODE so that the "AUTO"
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.
