INTRODUCTION
The Lowrance
X-3
Liquid Crystal
Graph (LCG) is a compact unit that
packs more power
and features
than any
other sonar using a liquid crys-
tal display (LCD.).
The
LCD. sets the X-3
apart from other sonar units. Instead of a
stylus
writing on chart paper or a flashing
neon light,
the
X-3 displays
the depth
information
on a screen
using small squares
which turn black when
an
echo
is received. As each echo is
detected,
the signals
move across the
screen, leaving
behind a record of the area that was
just passed.
No other
sonar has as many
automatic features as
the X-3. Once turned
on, it will find and display
the bottom
signal, fish,
and other targets.
As
the
depth of
the bottom
changes,
the X-3 will automatically
change the
range, sensitivity, and other controls
so that the bottom will always be
displayed
on the screen.
If
desired,
the only key on the keyboard
that
needs
to be touched is the off/on key.
However,
the X-3 has built in override
capability that allows the features
to be
used in any
combination
to best suit local conditions.
The
X-3 is
nitrogen
filled and sealed for
complete waterproof protection
of
the internal
parts. The
liquid crystal display and keyboard
are back-
lighted for
easy
use
at
night, and the X-3 is fully covered by
a one year
Lowrance full warranty
which covers all parts and labor for one year from
date of
purchase.
INSTALLATION
The X-3 may
be installed in any
convenient location,
provided it can be
tilted for the best viewing angle.
Roles in the bracket base allow wood
screw or thru
bolt
mounting. The bracket may be attached
to aluminum
panels
with sheet metal
screws, however,
a
piece of
plywood may be
required on
the back of thin
fiberglass panels
to secure the
mounting
screws. Stainless
steel is recommended
for all
mounting
hardware. Make
certain there is enough
room behind the unit to attach the power and
transducer cables.
A Ye" hole is in the base of the
gimbal bracket that allows the power and
transducer cables to be routed
straight down through the mounting
sur-
face.
The smallest hole that will pass one connector thru is ¾". This will
allow
the transducer connector and cable to be
passed up through the
hole and gimbal
bracket,
then the
power
cable wire can be
pushed down
thru the bracket and dash.
After the cables have been routed,
the hole
may be filled with silicone rubber adhesive
(RTV), or the bracket can be
offset so that the
majority
of the hole is covered.
