For extra tuning convenience, the SC-CH730 let you take advantage
of the Radio Data System (RDS) in areas where RDS broadcast
services are received. This advanced system simplifies operation
and provides useful information, utilizing a 57 KHz subcarrier above
the audible range, in addition to the main FM signal.
What is RDS (Radio Data System)?
RDS is a multiplex broadcasting system which adds a variety of
message signais to the audio signals of FM broadcasts.
This system can utilize the following signals among the various RDS
signals.
RDS messages used by this system:
@PS (Program service name):
Name of the broadcast station
®@PTY (Program type):
Identification
signal
for program
types such as news and sport
"PTY" may not be available in some areas. (Future function)
Functions of this system which use RDS
To display the name of a broadcast station (PS
display):
When this system receives a PS signal in an RDS broadcast, the
name of the broadcast station is shown on the display. (For details,
see the right of this page.)
To search for a program of a particular type, such
as news or sport (PTY search):
When you wish to listen to a particular type of program, a program of
that type can be searched.
Furthermore, while the PTY signal is being received, the name of the
type of program currently being broadcast can be shown on the
