SYSTEM OVERVIEW
1.8 DISPLAY BACKLIGHTING
The backlighting of the PFD and MFD displays and bezel and Audio Panel keys can be adjusted automatically or
manually. The default setting (automatic backlighting adjustment) uses photocell technology to automatically adjust
for ambient lighting conditions. Photocell calibration curves are pre-configured to optimize display appearance
through a broad range of cockpit lighting conditions. Manual backlighting adjustment can be accomplished using
the existing instrument panel dimmer bus or the following procedures. In normal operating mode, backlighting
can only be adjusted from the PFD. In Reversionary Mode, it can be adjusted from the remaining display.
