Selecting the Background Color
Five colors are available for the sonar display background – black, dark gray, light
gray, white, and dark blue. The color you select is used on all the sounder windows
(scrolling bottom, Zoom, Bottom Lock, and A-Scope).
You will probably find that you need to change the background color in different
light conditions. For example, a white background is probably easiest to see in
bright sunlight, but a black background may be preferable at night.
