Selecting the Background Color
The background color you select for the primary Sonar window is
used on all the Sonar 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. On the Pathfinder Panel, click the MULTI button.
2. Click Background Color . The background color buttons
are displayed below a pallet of available colors. The
currently selected color is highlighted.
3. Select the desired new color and click OK . The
background color changes.
4. Click ENTER , CLEAR , or BACK to return to the top-level
Functionbar menu.
Changing the Scroll Speed
The standard Fishfinder display is the scrolling bottom image, which
shows a graphical representation of the echoes seen by the Fishfinder.
New information appears at the right hand side of the display and
scrolls to the left.
The speed at which the display scrolls is adjustable, but the same
section of the bottom is displayed regardless of scrolling speed. If you
select a faster scroll speed, more detail is displayed (useful when you
are looking for fish). If you select a slower speed the information
moves by more slowly.
