Radio Data System (RDS)
The Radio Data System (RDS) is a system in which inaudible digital information is transmitted in addition to the normal FM radio programme. RDS
offers several useful features, the following are available on your radio:-
Programme Identification (PI)
This information consists of a code, which is assigned to each individual
radio programme to enable it to be distinguished from all others. It is not
intended for direct display or access by the user but used internally by
the microprocessor.
Programme Service (PS) name
The Programme Service name is a text usually consisting of not more
than eight alphanumeric characters. It indicates information about the
programme being broadcast. A station name or an abbreviation is
shown in the display instead of the tuned frequency (Example: BBC R4).
Traffic Information System
The Traffic Programme identification (TP) indicates which RDS stations
provide Traffic information. The Traffic Announcement identification
(TA) indicates Traffic information is being broadcast. When TA is
received, the
symbol will flash and the volume increases slightly.
Enhanced Other Network (EON)
Additional information about other programmes within the same network
is transmitted when your broadcasting station is using an Enhanced
Other Network. The EON indicator will be displayed and you will hear
traffic flashes of other programmes within the network automatically (if
the Traffic Announcement / EON function is switched on).
Clock Time (CT) automatic adjustment
The Clock Time information transmitted from the broadcasting station
can be used for setting and synchronising the clock of your radio
automatically. The Auto-Time function can be enabled or disabled by the
user.
Programme Type (PTY)
This is an identification number transmitted with each programme to
specify the type of the programme being broadcast e.g. NEWS, ROCK,
CLASSIC etc. The PTY number can be used so that search tuning
responds only to the selected programme type.
Radio Text (RT)
Radio Text is a text message of up to 64 characters in length. It is
displayed by scrolling the characters of the message from right to left.
Note: RDS features are available on the FM band only.
