ASP (Advanced Signal Processing)
ASP is a program embedded in the 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 mini-
mum of clutter. This feature is especially
useful since it typically lets you operate the
boat at all speeds without adjusting the sen-
sitivity or other controls. When the unit is first
turned on, ASP is enabled. To turn ASP off,
press a 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 PWR/CLEAR key to clear the
screen.
SIMULATOR
A simulator is built in that can show a simu-
lated bottom signal with fish. All features of
the sonar work normally when the simulator is
in use. You can change the range, zoom, and
use the alarms as desired. To use the simu-
lator, press a menu key repeatedly until the
SONAR SIM menu appears. Now press the
up arrow to turn it on. Repeat the above steps
to turn it off, or turn the unit off and back on
again.
