Radio Data System - RDS also referred to as RDS)
The SC-900/901 radio is equipped with an advanced system allowing information from broadcasters to
be transmitted inaudibly together with the audio signal. This information is then decoded by the SC-
900/901 and made available for several new and unique features. The RDS and Radio Data System
operates in the FM band only, and the information transmitted is supplied by participating
broadcasters. Volvo has no control over the accuracy of the data or information. Please refer to pages
176-181 regarding specific descriptions and operation of these functions. Volvo was among the first to
pioneer this technology throughout Europe and it is slowly making its way to North America.
Coverage by local broadcasters may be limited at this time, but as the technology and benefits grow,
you will find the SC-900/901 radio ready to advantage of this system.
Automatic tuning
This feature may not apply in your area. If you tune into a station using RDS, the frequency is displayed
followed by the name of the station in letters. The AF function ensures that the radio automatically tunes
into the most powerful transmitter for the selected program. Keep the FM button pressed down for at
least two seconds. 'AF Switch OFF' appears in the display for two seconds. If you want to switch on the
AF function, press the FM button for less than one second. 'AF Switch ON' then appears in the display.
