Adjust Display Brightness
Automatic Brightness Control
Dimming is limited to prevent on-screen indications from becoming unreadable. The
built-in photocell automatically controls display brightness based on ambient light
levels.
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.
WHERE TO FIND IT
