Contrast
You can adjust the LCD screen contrast to suit your viewing angle and
lighting conditions. To change screen contrast, press and hold the ESC
pushbutton for two seconds. The SEL-787 displays a contrast adjustment box.
Pressing the Right Arrow pushbutton increases the contrast. Pressing the Left
Arrow pushbutton decreases the screen contrast. When you are finished
adjusting the screen contrast, press the ENT pushbutton; this process is a
shortcut for changing the LCD contrast setting FP_CONT in the front-panel
settings.
