switch to metric, the up arrow to switch to feet. Displays show in feet when
the unit is first turned on. The menu will clear automatically after a few

DISPLAY CONTRAST
The unit’s display contrast is adjustable to suit different lighting conditions.
This will help you see the screen from different angles, or at various times
of the day.
To adjust the contrast, press the menu key
until the DARK/LIGHT menu appears. To
decrease it, press the down arrow key. Press
the up arrow key to increase the contrast.
The bar graph in the Dark/Light menu box
shows a graph of the contrast. The screen
will also show the effects of the change. If you
reach the maximum or minimum level, a tone
sounds alerting you to the limits. The menu
will clear automatically after a few seconds or
press the ON/CLEAR key to clear the screen.
ASP (Advanced Signal Processing)
ASP is a program embedded in the X-25B’s computer that is specifically
designed to eliminate noise. It continually monitors the signals from the
receiver, determines which echoes are noise and rejects them. This allows
true target echoes to display on the screen
with a minimum of clutter. This feature is
especially useful since it typically lets you
operate the boat at all speeds without adjust-
ing the sensitivity or other controls. When the
X-25B is first turned on, ASP is enabled. To
turn ASP off, press the menu key repeatedly
until the ASP menu appears. Now press the
up arrow to turn it on or the down arrow to turn
it off. The menu will clear automatically after
a few seconds or you can press the ON/
CLEAR key to clear the screen.
