Tune Control

The tuning control is a continuous rotary knob with 20 detents per revolution. Press the knob lightly in order to extend the knob to the out position. Turn the controls in the following directions in order to tune the receiver:
^ Turn the controls clockwise in order to increase the frequency.
^ Turn the controls counter-clockwise in order to decrease the frequency.

Adjusting the tuning control stops the SEEK and the SCAN functions. Tuning then continues from the frequency where you last stopped the SEEK or the SCAN function.
