pg. 142 RDS
Radio Data System
The Volvo HU -555 is designed for the digital information system RDS (Radio Data System).
RDS features automatic programming and instant traffic information and it broadens the possibilities for program
choices. The transmitter broadcasts information about the program. This information is represented by a data code,
which identifies the program, irrespective of which frequency the information is transmitted.
This means that the driver does not have to change the frequency if he wants to continue listening to the same
program. Every station/program has a specific identification which the radio searches for.
The RDS radio can also receive traffic information. This is transmitted with a special signal which cuts through any
normal radio transmission, or CD play back and is always heard at its own adjustable volume.
PTY (Program Type) information, which is an extension of the RDS system, is also transmitted in certain areas.
There are a number of other features in the RDS -system, such as time control signals, alarms etc.
