Tune Control

On the UN6 and UM7 model, the tuning control is a continuous rotary knob with 20 detentes per revolution. Turn the control in the desired direction in order to tune the receiver:
^ Clockwise turning increases the frequency
^ Counterclockwise turning decreases the frequency.

The ULO, UNO, and UPO models, incorporate a vertically-mounted tuning control button.
^ Pressing the top portion of the button increases the frequency.
^ Pressing the bottom portion of the button decreases the frequency.

Frequency is either increased or decreased by one channel per detente.

Adjusting the tuning control will stop the SEEK and SCAN functions. Tuning will then continue from the last frequency where the SEEK/SCAN function stopped. The tuning function is replicated on the steering wheel controls with the separate SEEK and SCAN buttons, when equipped.
