(Advanced
Signal Processing)
ASP is a
program
embedded in the
UltraNav's
computer
that
continu-
ally
monitors the
signals
from
the receiver, It determines which
echoes are
noise,
rejects them,
allowing target
echoes to be
displayed
with a minimum of screen
clutter. This feature is
especially useful,
since it
typically
allows
you
to
operate
the
boat
at all
speeds
without
adjusting
the
sensitivity.
When the
UltraNav is first turned
on,
ASP is
enabled. To turn
ASP
off,
press
the menu
key
seven times.
The
menu shown
above on the left
appears.
Now
press
the
key adjacent
to the "Turn Off
ASP'
label.
The unit will
return to the sonar screen
with ASP off. To turn ASP
on
again, repeat
the above
steps.
