4.5.1.1 DIMMING CONTROL

The Dimming Control setting allows the installer to select the source of dimming control. It

can be an “EXTERNAL” source, typically the aircraft’s adjustable lighting bus, or it can use

the integrated photocell built into the unit (“INTERNAL” option) which senses the ambient

light conditions and adjusts the display brightness/dimming automatically. If an external

source is to be used, the EXT 5V, EXT 14V, and EXT 28V options represent the input

voltage range the unit will accept (0-5VDC, 0-14VDC, and 0-28VDC, respectively). This

feature is provided for maximum installation flexibility and control for the pilot. (Figure 4.8)
Selecting any option will save that setting and revert to the Dimming Configuration Menu.
