regional networks are carrying the
same programming, but can cause
'random' AF switches if they are not.

ALTERNATIVE
FREQUENCIES
Many programmes broadcast on the
FM waveband have a programme
identification (PI) code, which can be
recognised by audio units.
If your radio has AF tuning switched
on and you move from one
transmission area to another, this
facility will search for and switch to a
stronger station signal, if one can be
found.
Under certain conditions, however,
alternative frequency tuning may
temporarily disrupt normal reception.
With ‘AF-ON’ or ‘AF-AUTO’ selected,
the unit continually evaluates signal
strength and, if a better signal
becomes available, the unit will switch
to that alternative. It mutes while it
checks a list of alternative
frequencies and, if necessary, it will
search once across the selected
waveband for a genuine alternative
frequency.
It will restore radio reception when it
finds one or, if one is not found, the
unit will return to the original stored
frequency. On certain units, ‘Not
Found’ will be displayed.
With ‘AF-MAN’ selected, the unit
operates in a similar way to
‘AF-AUTO’ or ‘AF-ON’, but only
searches for an alternative frequency
when prompted by pressing a preset
button.
With ‘AF-OFF’ selected, the original
stored frequency remains selected.
In this mode, ‘AF-OFF’ will be
displayed every time the unit is turned
on.
