1.3.4 Display Backlighting
The backlighting of the PFD and MFD displays and bezel 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.
Backlighting Adjustment
1) From the first AUX page, press the small MFD knob to highlight the “Display
Brightness” “Mode” box.
2) Turn the small MFD knob to select the desired brightness Level and then press
ENTER.
