BRIGHTNESS AND LIGHTING CONTROLS
The following table describes the means available by which to
control the display and bezel backlighting/brightness:
Control Method
Comments
Dimming Bus
If set up to use the dimming
bus in the Configuration pages
at time of installation, then both
the bezel and the display
brightness/backlighting will be
controlled via the cockpit
dimming bus controls, typically
a dimming rheostat.
Ambient Light Sensor
If set up to use the ambient
light sensor that is embedded
in the AXP340 bezel from the
Configuration pages at time of
installation, then both the bezel
and the display
brightness/backlighting will be
automatically controlled via
internal software algorithms in
response to measured ambient
light conditions.
Manual Control (display only)
Accessible via the FUNC key
on the AXP340 front panel.
Once the LCD Brightness page
is displayed, a scale of 1 to 10
is controllable via the bezel
selector knob.
