Tethering the Light Sensor
The protruding circuit board area containing the light sensor is designed so it can be
snapped off and removed from the main interface board. Once the ambient sensor is
removed it will require the addition of a cable between J3 and J8 in order to function.
With the cable installed the sensor can be remotely positioned. The sensor may be
discarded if the ambient sensing capability is not required.

removed it will require the addition of a cable between J3 and J8 in order to function.
With the cable installed the sensor can be remotely positioned. The sensor may be
discarded if the ambient sensing capability is not required.
To remove the light sensor, place the thumb of your right and left hand on the
corresponding front surfaces of the sensor circuit board. Place the index fingers of both
hands on the display’s rear circuit board just above the sensor. With a firm quick action,
push the sensor circuit board back. This will cause the circuit board to snap along the
perforation. Now rock the sensor circuit board back and forth several times until it is free
from the main interface board.

Connect a cable from J8 on the rear of the sensor circuit board to J3 on the rear of the
display. The ambient light sensor should now function normally.
