13.AF [ALTERNATIVE FREQUENCIES] BUTTON
When pressed briefly, AF switching mode is selected and the state of AF switching
mode is displayed by AF segment in display.
Segment off: AF switching mode off.
Segment on: AF switching mode on, and has RDS information.
Segment flashing: AF switching mode on, but RDS information is not received yet.
When AF switching mode is selected, the radio checks the signal strength of AF all
the time. The interval of checking time of each AFs depends on the signal strength
of current station, from a few minutes for a strong station to a few seconds for weak
station. Every time that new AF is stronger than current station, it switches over to
that frequency for very short time, and NEW FREQUENCY is displayed for 1-2
seconds.
Because the mute time of AF switching or checking time is very short, it is almost
inaudible in case of normal program.
During FM mode, when AF is on, SEEK, (SCAN), AUTO-MEMORY function can only
receive and save RDS program.
