Operation.
This
chapter
will
explain
the other features that
will enable the serious
operator
to
get
the maximum
use out of
your
EAGLE.
We
urge you
to read this manual
thoroughly
and familiarize
your-
self with the controls.
Although
this is
a
very
advanced
unit,
it is
easy
to
use,
thanks to the
power
of the
microcomputer
and the
front
panel
controls. Should
you

INSTALLATION
Mounting
—
The
depth
sounder
may
be in-
stalled in
any
convenient
area,
provided
the unit can be tilted for
the best
viewing angle.
Holes in
the bracket allow wood screw or
thru bolt
mounting.
A wood stiff-
ener
may
be
required
on the back
of thin
fiberglass panels
to
sup-
port
the unit.
If the desired location is closer
than 18" to a
magnetic compass,
a trial run should be made with
the unit in
operation
to be sure
that the
compass readings
are
not affected.
POWER CONNECTIONS
12 volt DC
power
for the sonar
unit should be
supplied
from the
boat's 12 volt DC electrical
sys-
tem. The
power
cable
may
be at-
tached to an
accessory
or
power
buss,
but if
you
have
problems
with electrical
interference,
the
cable should be attached
directly
to the
battery.
If a
longer
cable is
required,
use
ordinary
#18
lamp
cord
available
at
any
hardware
or electronic
supply
store.
Splices
should be
soldered.
If this can't be
done,
use
crimp
type splices. Tape
all
connections
with electrical
tape.
An
in-line fuse holder with fuse is
supplied
with
the EAGLE
graph.
Be certain to install this fuse
holder as close to the
power
source
as
possible.
This will
pro-
tect both the sonar unit and the
power
cable in the event a short
occurs.
Crimp
connectors are
supplied
to attach the fuse holder
to the
power
cable. The red wire
in the
power
cable is the
positive
conductor. The black wire is the
ground
or
negative
conductor.
The
graph
is
protected
from acci-
dental
polarity
reversals and
no
damage
will occur if the wires are
reversed.
However,
the unit will
not
operate
until the
proper polar-
ity
is
applied.
