Tune Control

The following factors describe tuning control:
^ The tuning control is a continuous rotary knob with 20 detents per revolution. This is a pop out knob on Oldsmobile models.
^ Tune the receiver by turning the control in the desired direction.
Clockwise turning increases the frequency or amplitude.
Counterclockwise turning decreases the frequency or amplitude.
^ Frequency or amplitude increases or decreases by one channel per detent.
^ Adjust the tuning control in order to stop the SEEK and SCAN functions. Tuning will then continue from the frequency that the receiver was at when the function was stopped.
^ The tuning function is replicated on the steering wheel controls with separate tune buttons (when equipped).
