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.
