Display Lighting
The EFD1000/500 MFD contains various lighting controls to maintain readability under
all lighting conditions. Each EFD1000/500 MFD has an LED backlight, which illuminates
textual content for better night operation. The controls are also backlit, at a fixed
brightness, for visual location in dark conditions.
The display itself contains an adjustable backlight with a wide dimmable range. The
pilot can choose between Automatic or Manual display lighting mode. By default, the
EFD1000/500 MFD is in AUTO display lighting mode. The front mounted photocell
measures the ambient light and adjusts the backlighting automatically to a readable
level
(Figure 4-26)
.
When the MENU Button is pressed and the menu system is active, the Left Knob can be
used to adjust the EFD1000/500 MFD display brightness.
By default, the LCD brightness operates in AUTO mode, and is adjusted based on
photocell sensing of ambient lighting conditions. When the MENU is active and the
display brightness is in AUTO, the word AUTO and a brightness level of 1-100 will be
displayed in green above the Left Knob.
To override the AUTO brightness setting, press the Left Knob once to switch into
Manual mode, and then rotate the Left Knob to set the brightness to the desired level.
To return to AUTO brightness control, press the Left Knob again.
