FEET/METER
The X-45 can show the depth in feet or
meters, temperature in degrees Fahrenheit
or Celsius, speed in statute miles per hour or
knots, and distance (log) in statute miles or
nautical miles. When the unit is in the metric
mode, all depth readings, ranges, zooms,
and alarm settings are in meters. When a unit
is in the feet mode, all of the above settings
are in feet.
To change from feet to meters or vice-versa,
press the menu key until the FEET/METER
menu appears as shown at the bottom of the previous page. Press the
down arrow key to 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 seconds or you can press the ON/CLEAR key to
clear the screen.
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 you can press the ON/
CLEAR key to clear the screen.
ASP (Advanced Signal Processing)
ASP is a program embedded in the X-45’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
