Figure 1:

The balance, treble, bass and fade buttons on the upgrade radios in our 1988-89 C/K models each have three functions:
1. Centering function. Press the button in the center and feature sets in a neutral position.

2. Increase function. Press + or > and the feature increases.

3. Decrease function. Press - or < and the feature decreases.
On 1988 model trucks the increase and decrease indicators were centered on the ends of the buttons; however, the increase and decrease switches are located under the corners of the buttons. Starting in calendar year 1989 the indicators + or >, - or < were relocated on the corners of the buttons for more positive operator input on the bass, treble, balance and fade buttons. Customers inquiring about radio push button sensitivity should be advised of the facts above. Radios should always be checked to verify improper function before removal for repair.
