The AF (Alternative Frequencies search)
function is used to search for other frequencies
in the same network as the currently tuned
frequency. It automatically mutes the sound
and retuneds the receiver to another frequency
in the network which is broadcasting a stronger
signal when there are problems with reception
of the currently turned station or better reception
is possible on a different frequency.
