6. AF [ALTERNATIVE FREQUENCIES] BUTTON

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 the current station, from
a few minutes for 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 a very
short time, and the 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.
When pressed long, AF mode is converted to REGION ON/OFF mode.
