Selecting the Background Color
Five colors are available for the fishfinder display background – black, dark
gray, light gray, white and dark blue. The color you select is used on all the
fishfinder 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.

To change the background color:
1. Press the
MULTI
key to display the soft key controls, then press
COLOR SET-
TINGS.

soft key. The background color soft keys
are displayed below a pallet of available colors. The selected color is high-
lighted.
3. Press the left or right

soft key until the required color is
highlighted.
The fishfinder display changes, so you can see the effect as you change the
background color.
4. Press

or

twice to return to the
MULTI
soft keys.
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 minimum strength that is displayed by blanking
echo colors below the required minimum.
