Light Detector
The light detector must be mounted near the display so that the light detector is facing the same
direction as the face of the display. A 4-conductor cable is used to connect this light detector to
the display. The cable is terminated on the controller board on the terminal block labeled “TB2.”
Refer to Drawing A-76570.
