Automatic retuning for best
reception results
— AF function
The alternative frequencies (AF) function allows
the radio to always tune into the area’s strongest
signal for the station you are listening to.

Press (AF) repeatedly until “AF-ON”
appears.
The unit starts searching for an alternative
frequency with a stronger signal in the same
network.
If “NO AF” flashes, the currently tuned into
station does not have an alternative frequency.
Note
When there is no alternative frequency in the area or
when you do not need to search for one, turn the AF
function off by selecting “AF-OFF.”
For stations without alternative
frequencies
Press either side of (SEEK) while the
station name is flashing (within 8
seconds).
The unit starts searching for another
frequency with the same PI (Programme
Identification) data (“PI SEEK” appears).
If the unit cannot find the same PI, the unit
returns to the previously selected frequency.
Staying with one regional programme
When AF function is on: this unit’s factory-set
setting restricts reception to a specific region, so
you won’t be switched to another regional station
with a stronger frequency.
If you leave this regional programme’s reception
area or would like to take advantage of the whole
AF function, select “REG-OFF” from the MENU
(page 22).
