the water.
Periodically,
the rubber roller on
the
paper

Surface
Clarity
Control
(SCC)
The surface
markings
at the
top
of
the chart
paper
can,
at
times,
extend
many
feet below the
surface.
This often interferes
with
fish
signals
or other
targets.
This
is called Surface
Clutter and is
caused
by algae
and
plankton,
air
bubbles caused
by
wave action or
boat
wakes,
bait
fish,
or
temperature
inversions.
The surface
clutter
markings
can be reduced or eliminated
by
using
the SOC
control
key
on the
front
panel keyboard.
To use the
3CC, press key
1
thru 7
(depending upon
the
amount of 3CC
desired)
and then
the SCC
key.
1 has
a minimum
effect on surface
clutter,
7 has the
maximum effect on
reducing
surface clutter. 2 thru 6 have
intermediate effects.
The amount
of SCC that is used is
printed
at
the bottom of the
chart
paper.
If
one level
of SCC is
used,
then
3CC-i is
printed.
Two
levels,
SCC-2,
