FINE button

Press to reduce the Tuning control step size by one-tenth to allow more precise tuning {page 21}.

1MHz button

Press to switch between the 1MHz mode and the Amateur band mode {page 20}. This button also activates the Programmed channel and Vacant channel search modes {page 55}.

@7Tuning control

Turn to select the desired frequency. Use the convenient finger-tip cavity for continuous tuning {page 21}.

@8Mode buttons

Press these buttons to select your operating mode {page 20}.

LSB/USB button
