1.4.5 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.

BRIGHTNESS” “MODE” box.
