If Auto (AUTO) is selected, the color of the lettering in the
information display (
0 12) will automatically change from black to
white or white to black to maintain contrast with the background.
To always use the same color lettering, select Manual and choose
Dark on light (B; black lettering) or Light on dark (W; white
lettering). Monitor brightness will automatically be adjusted for
maximum contrast with the selected text color.
If Off is selected, the control panel and button backlights
(illuminators) will only light while the power switch is rotated
toward

standby timer is active ( 0 44; note that regardless of the option
selected, the backlights turn off while the shutter-release button is
pressed). Select Off for increased battery life.
