2.6 Display Brightness
When the MENU button is pressed and the Menu is active, the Left Knob can be used
to adjust the PFD display brightness.
NOTE
When the PFD is operation on the internal battery, the maximum brightness level
is limited to 40% in automatic mode and 70% in manual mode to preserve battery
operating time.
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 LCD
is in the BRT AUTO mode, the word, “AUTO”, and a brightness level will be displayed in
green above the Left Knob (Figure 2-17). The maximum intensity in AUTO mode is 70%.
To override the AUTO brightness setting, press the Left Knob once to switch to the BRT
ADJUST mode, and then rotate the Left Knob to set the brightness to the desired level
(Figure 2-18). To return to AUTO brightness control, press the Left Knob again.
NOTE
To facilitate cooling of the PFD, when the backlight temperate us greater than 70C, the
display brightness level is limited to 40% in automatic mode and 70% in manual mode
to preserve battery operating time.

NOTE
The BRT AUTO display brightness level is determined
by the amount of light detected by the photocell on
the front of the PFD. If a light is used to illuminate the
instrument panel, the photocell will respond, resulting
in a bright display. When this happens, use the manual
BRT ADJUST mode to reduce the brightness.
