RDS Operations

RDS (Radio Data System)
This unit has a built-in RDS decoder system that
supports broadcast stations transmitting RDS data.
This system can display the name of the broad-
cast station being received (PS) and can auto-
matically switch to the broadcast station with the
best reception as you move long distances (AF
switching).
Also, if a traffic announcement or programme
type is broadcast from an RDS station, no matter
what mode you are in, this broadcast is received.
Additionally, if EON information is received, this
information enables automatic switching of other
preset stations on the same network and inter-
ruption of the station being received with traffic
information from other stations (TP). This func-
tion is not available in some areas.
When using the RDS function, always set the
radio to FM mode.
