The AFC (Automatic Frequency Control) function tunes the
displayed frequency automatically when an off-center fre-
quency is received. It activates in FM/WFM modes only with
single band operation.
➥
Push [0 AFC] to toggle the AFC function ON and OFF.
• “AFC” appears when the AFC function is in use.
NOTE: The AFC function is not available during dualwatch
operation.
■ NB/ANL function
The NB (noise blanker) function removes pulse-type noise
when USB, LSB or CW mode is selected. The ANL (Auto-
matic Noise Limitter) function reduces noise components
when AM mode is selected.
See page 22 for setting details.

eration, but both functions are active while in specific
