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.

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 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).

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.

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).

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.
