7.4. DISPLAY BRIGHTNESS
From the factory, the GNC 255A automatically adjusts its display brightness for the
current lighting conditions. A small sensor on the display is used for this function. A
manual adjustment is available for controlling the brightness level of the display as an
offset from the normal or zero position.
The GNC 255A will either control dimming based on the photocell or the lighting bus.
This is set in configuration mode during installation and is not selectable by the pilot.
