Receiving FM Stations with RDS
RDS (Radio Data System) is a broadcasting service which a growing number of FM stations are now
providing. It allows the FM stations to send additional signals along with their regular programme signals.
For example, the stations send their station names and information about what type of programme they
broadcast, such as sports or music, etc.
When tuned to an FM station which provides the RDS service, the station frequency (and then the station
name if sent) is displayed.
One convenient RDS service is “Enhanced Other Networks (EON)”. This allows the Unit to automatically
switch to a programme type of your choice when one starts in your broadcast area.
Not all FM stations provide RDS service, nor do all RDS stations provide the same services. If in
doubt, check with local radio stations for details on RDS services in your area.
Note: RDS may not work correctly if the station to which you are tuned is not transmitting properly or if
the signal strength is weak.
