The system display and control backlighting can be adjusted either automatically or manually.  Backlighting 

intensity ranges from 0.14% to 100% on the PFDs and 0.80% to 100.00% on the MFD.

The existing instrument panel dimmer bus normally controls the PFD and MFD backlighting as well as 

the PFD and MFD bezels, MFD Control Unit, AFCS Control Unit and audio panel key annunciator lighting.  
When the dimmer bus is not used by the system, photocell technology automatically controls backlighting 
adjustments.  Photocell calibration curves are pre-configured to optimize display appearance through a broad 
range of cockpit lighting conditions.

The avionics dimming knob may also be used to adjust backlighting.  Refer to the AFM for details.

In normal mode, backlighting can only be adjusted from PFD1 or PFD2.  In reversionary mode, it can 

also be adjusted from the MFD.

No other window can be displayed on the PFD while the PFD Setup Menu Window is displayed.

Backlighting may also be adjusted manually for all of the displays and the associated bezels.

  

The audio panel 

key backlighting is directly tied to the on-side PFD key backlighting setting.
