5-4 DSM250 Digital Sounder Module
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 back-
ground is probably easiest to see in bright sunlight, but a black
background may be preferable at night.

keys are displayed below a pallet of available colors. The selected
color is highlighted.

Selecting the Color Threshold
You use the color threshold control to determine the minimum
echo strength that is displayed. Each range of echo strengths is
displayed in a color as shown in the color bar; you select the min-
imum strength that is displayed by blanking echo colors below the
required minimum.
If you blank a color, the corresponding echoes are displayed in the
background color. You can remove up to six colors, but you can-
not remove the strongest color.
The color threshold you select is used on all the sounder windows
(scrolling bottom, Zoom, Bottom Lock, and A-Scope).
