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 alternative frequencies
(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, AF
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.

NEWS BROADCASTS
Some audio units interrupt normal
reception to broadcast news bulletins
from stations on the FM waveband or
radio data system (RDS) and enhanced
other network (EON) linked stations, in
the same way as traffic information is
provided.
During news broadcasts, the display
alternates between the station name
and 'NEWS'. News interrupts are
broadcast at the same preset volume
level as traffic announcements.
