Storing channels automatically
This function automatically stores stations
with adequate reception under the presets.

reception strength and stored. The search
starts at the lowest frequency. Audio 20
stores any stations found, beginning with pre-
set 1. The storing process ends once the
highest frequency has been reached or once
ten stations have been found and stored. Any
channels stored manually under the presets
will be lost. Under certain circumstances,
Audio 20 will not use all presets.

Radio Data System (RDS)
General notes
Radio Data System (RDS) provides additional,
inaudible information on the FM waveband.
The system consists of a listening receiver
and a monitoring receiver.
The monitoring receiver constantly scans the
FM waveband and collects data from all the
stations which can be received, e.g. reception
quality and RDS data such as programme
name and alternative frequencies. Audio 20
stores the data and constantly updates the
presets. Therefore, the listening receiver is
able to switch inaudibly to an alternative fre-
quency with a better signal.
i The Radio Data System only functions
with stations which transmit RDS data.
Switching RDS on/off
The "Frequency fix" function prevents Audio
20 from switching between a radio station's
alternative frequencies. This is useful, for
example, when there is a noticeable time off-
set between the frequencies or if there is
interference on a frequency.
