Automatic retuning for best 
reception results 
— AF (Alternative Frequencies)
The AF function allows the radio to always tune 
into the area’s strongest signal for the station you 
are listening to.
1
Select an FM station (page 14).
2
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.
Notes
• If you want to change the on/off setting while playing 
an MD, press 
(AF)
.
• 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 
(SEEK)
 (+) or 
(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, press (AF) for 2 seconds until   
“REG-OFF” appears.

This function does not work in the United Kingdom
