Display Lighting Level
Display lighting level
The SID unit calculates a suitable lighting level using the rheostat level and the level of light intensity in the car, which comes from the light sensor.
The display is lit by 4 bulbs easily accessible from the rear of the SID unit.
In the dark, the rheostat level controls the lighting. When the light level in the car increases, the value for the light intensity in the car takes over. This
ensures that all displays remain legible.
The SID unit sends the calculated value out on the bus as DISPLAY LIGHTING LEVEL, unit %.
