Table 6-8
The DP-884 Dimmer Panel provides the brightness control for the six
display units. The controls consist of three dual concentric clutched
potentiometers. One dual concentric potentiometer each controls the
pilot's PFD/ND pair, the EICAS DU pair, and the copilot's PFD/ND pair.
The panel contains no electronics. The actual brightness control
function takes place within the DUS. With the DP-884 Dimmer Panel
removed, the displays revert to a median value. The displays also go to
a median value with potentiometers open or shorted.
