Display Brightness Control
Automatic Brightness Control
Manual Brightness Control
Optionally, the unit is configurable to use an aircraft dimming bus for display
brightness control. Upon reaching minimum input level, display brightness reverts to
the photocell. This prevents the display from going black in the event of a dimmer
input failure.
Installer configured curves determine the amount of change in brightness that
occurs in response to a control adjustment.
If brightness control is not satisfactory, contact a Garmin dealer to adjust the
lighting curves.
Depending on configuration, display brightness is controlled
using inputs from the built in photocell, aircraft dimmer bus,
or both.
Dimming is limited to prevent
on-screen indications from
becoming unreadable. The built in
photocell automatically controls
display brightness based on
ambient light levels.
During automatic control, the pilot
may still adjust brightness using
the manual offset controls in the
Backlight page.
The unit retains manual offset
settings over power cycles.
