This control selects the desired frequency band.

- -4Frequency Selector

This detented control is a 360º multi-position switch used to increase or decrease the operating frequency in 5 or 10 kHz steps within the selected band.

- -4+10 kHz

When this button is in the out position, the operating frequency is increased or decreased by 5 kHz with each click of the frequency selector knob. When the button is in the in position, faster tuning is available because the operating frequency is increased or decreased by 10 kHz with each click of the frequency selector knob.
