About RDS
This unit is equipped with RDS (Radio Data
System), which brings a wide range of informa-
tion to FM radio. Now in use in many countries,
RDS is a system for transmitting station call signs
or network information, a description of station
programme type text message about the station
or specifics of musical selection and the correct
time.
RDS Tuning
When a FM station is tuned in and it contains
RDS data, the unit will automatically display the
station’s call sign and the RDS indicator will light
in the Display Window as well as indicators for
the programme type recognition (PTY), Radio
Text (RT), Clock Time (CT) and RDS services
programme (PS) if transmitted by the station.
RDS Display Options
The RDS system is capable of transmitting a
wide variety of information in addition to the initial
call sign that appears when a station is first
tuned. In normal RDS operation the display will
indicate the station name, broadcast network or
call letters. Pressing RDS on the front panel
enables you to cycle through the various data
types in the sequence:
(PS FREQUENCY
PTY
RT
CT)
•
PTY (Programme type recognition)- The name
of the programme type is shown in the Display
Window.
•
RT (Radio text recognition)- The name of the
radio text is shown in the Display Window.
•
CT (Time controlled by the channel)- Enables
the unit to receive the actual time and show it in
the Display Window.
•
PS (Programme Service name)- The name of
the channel is shown in the Display Window.
ote
Some RDS stations may not choose to include
some of these additional features.If the data
required for the selected mode is not being
transmitted, the Display Window will show a
PTY NONE, RT NONE, CT NONE, PS NONE
message.
Programme Search (PTY)
A major benefit of RDS is its ability to encode
broadcasts with Programme Type (PTY) codes
that indicate the type of material being broadcast.
The following list shows the abbreviations used to
indicate each PTY along with an explanation of
the PTY.
You may search for a specific Programme Type
(PTY) by following these steps:
1.
Press TUNER/BAND to select FM mode.
2.
Select a desired station by pressing
TUNING (+/-). When the RDS transmission is
received, the display shows the program
service name (PS) after RDS indicator
appears.
3.
Press the RDS to select PTY mode.
4.
To search for a different PTY, press the PRESET
(+/-) while the last PTY in use is still
displayed to scroll through the list of available
PTY types.
5.
When the PTY is selected, press the
(
.m/M>
) within 5 seconds.
The unit will go into an automatic search
mode and attempt to find the next station
with acceptable signal strength that matches
the desired PTY type.
