Display Lighting
The EFD1000/500 MAX MFD contains various lighting controls to maintain readability
under all lighting conditions. Each EFD1000/500 MAX 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. The
front mounted photocell measures the ambient light and adjusts the backlighting
automatically to a readable level (
Figure 4-25
).
When the MENU Button is pressed and the menu system is active, the Left Knob can
be used to adjust the EFD1000/500 MAX 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.
