adjusted separately for the DZMx and the remote head. The DZMx can support variable lighting
which can be controlled from the aircraft dimmer control. Aircraft without dimmer controls can
manually set the brightness to Day and Night levels. Day backlight is set at maximum brightness
for both the keypad and the display. Night backlight can be adjusted separately for the keypad
and LCD display.
External lighting provides the user with the ability to dim or brighten the display by adjusting the
lighting control input. External lighting is only available if the DZMx or DZMx Plus is connected to
