detail, you
may
wish to turn the ASP feature off. If
there are
high
levels
of noise
present,
ASP will not
only
filter out the
noise,
but other small
echoes such as the above, If
you
do have noise
problems,
see the
sonar
troubleshooting
section in this manual.
To turn ASP
off,
first
press
the MENU
key,
then
press
the
key adjacent
to the "More" label until the 'Turn ASP
Off" label
appears.
Now
press
the
key
next to that label. The Z-9500 returns to
the sonar screen,
You should see an increase in noise on the
display.
To turn ASP on
again, repeat
the above
steps,
then
press
the
key adjacent
to the "Turn
ASP On" label.
FISH ID.
The
Fish
l.D.
feature identifies
targets
that meet certain conditions as
fish.
The
micro-computer analyzes
all echoes and eliminates surface
clutter, thermoclines,
and other
signals
that are undesirable. In
most
instances,
remaining targets
are fish. The Fish l.D. feature
displays
symbols
on the screen in
place
of the actual fish echoes, There
are
three fish
symbol
sizes:
small, medium,
and
large.
These are used to
designate
the relative size between
targets.
In other
words,
it
displays
a small fish
symbol
when it thinks a
target
is a small
fish,
a
medium fish
symbol
on a
larger target,
etc.
The
micro-computer
is
sophisticated,
but it can be fooled. It cannot
distinguish
between fish
and other
suspended objects
such as
trotlines,
turtles, submerged floats,
air
bubbles,
etc. Individual tree limbs extend-
ing
outwards from a
group
of limbs is the hardest
object
for the Fish
l.D. feature to
distinguish
from fish. You
may
see Fish l.D.
symbols
on
the screen when
actually,
there are no fish. Practice with the unit in
