Display Dimming

Display dimming is controlled by the BCM based on input received from the dimming potentiometer. The dimming potentiometer is connected between circuit 1359 and circuit 1381. The BCM monitors these inputs and provides a Pulse Width Modulated (PWM) output at circuit 8 to operate the display lamps.
