assembly so it can be easily flush mounted

against the back of the display housing.

Ambient light can then be directed to the

sensor through a small hole in the display

bezel, a panel mounted light pipe, or

transparent or translucent opening in the

display housing.

... Adjusting the light gain, using jumpers J1 to J3: The LXMG1800_LS comes from the factory preset with a solder bridge across jumper J1, as described in Jumper Gain Setting Table on page two. Light sensitivity will be reduced further by creating a solder bridge(s) across jumpers any combination. Reducing light sensitivity means that it will take a brighter light striking the sensor to signal the inverter to drive the panel to full brightness ...
