Secondary services - DAB
1. Certain radio stations have one or more secondary services associated
with them. If a station has a secondary service associated with it the
display will show ">>" next to the station name on the station list. The
secondary service will then appear immediately after the primary
service as you rotate the Tuning control.
2. To tune to the secondary service, press and release the Select button.
Most secondary services do not broadcast continually and if the selected
service is not available, the radio will retune to the associated primary
service.
