1.7 DISPLAY BACKLIGHTING
Backlighting of the PFD(s) and MFD, Audio Panel keys, and Control Unit keys can be adjusted automatically

calibration curves are pre-configured to optimize display appearance through a broad range of cockpit lighting
conditions. In normal display mode, backlighting can only be adjusted from the PFD(s). In Reversionary Mode,
it can be adjusted from the remaining display(s).
