Depth Digit Size
This setting controls the size of the digital depth readout at the lower left of 
the screen. Choose from the following:
LARGE (default)
SMALL 
Transparent Menu
This option removes the background white from the menu dialog box, 
enabling you to see data that would normally be hidden.
OFF selects a normal opaque Menu box, which is the default setting.
ON selects the transparent Menu box.
PALETTE...
The DS400/500 offers you six different display color combinations. You can 
select the color set, for a bold or soft color palette. The brightness of the 
screen can be adjusted over a wide range, suitable for viewing in daylight 
(high brightness level) or at night (low brightness level).
Selection
Select the optimal color scheme for your lighting conditions:
CLASSIC (default)
SUNBURST 
GRAYSCALE 
INV. GRAY 
COPPER 
NIGHT VISION 
Background Color
When the CLASSIC Palette is selected, you can also choose the background 
color used. Three colors are available for the sonar display background – 
black, white and blue.
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.
