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 the photocell located at the top right corner of the bezel to
automatically adjust for ambient lighting conditions. Photocell calibration
curves are configured by the installer 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.
3) Turn the large MFD knob to highlight the MODE field. Turn the small MFD
knob to select "AUTO" or "MANUAL."
4) Press ENT.
