Specifications
REMOTE
-
An
intelligent
"repeater"
unit that receives
depth
information
from another sonar unit.
A remote doesn't have
a
transmitter
or
receiver.
However,
It
does
have It's own features
that are
adjustable
and
operate
separately
from
the master.
RESOLUTION
-
The
ability
of a sonar unit to
separate
targets
from each
other or the bottom.
RMS A standard
rating
of
transmitter
power output.
SCALE
-
The
markings
on a sonar
unit's
display.
To determine
the
depth
of a
target, simply
compare
the
target's
location.to
the location of
the scale
markers on
the
display.
SECOND
ECHO -Another echo that
registers
at
roughly
twice the
depth
of a
target
echo.
This is caused
by
the sound
waves
reflecting
off the
bottom, striking
the surface of
thewater, travelling
tothe bottom
again,
and
returing
to
the surface.
SECOND
FUNCTION KEY
-
A button
that converts the functions
of the
primary keys
on
the
keyboard.
Sonar units
with a second function
key
have other
keys
with two functions.
You can switch functions
with the
second function
key.
SENSITIVITY
-
The
ability
of
a sonar unit's receiver
to
display targets.
Increasing
the
sensitivity
allows weaker
targets
to
be
displayed.
Also
called
"gain".
SCROLL SPEED
-
See CHART
SPEED.
SHOOT-THROUGH-HULL
-
A transducer installation
which allows
the
sonar
signals
to
pass
through
a
fiberglass
hull without
cutting
a hole in the
hull.
SUPPRESSION
-
A method used In
some sonar unltsto eliminate
interfer-
ence or noise.
SURFACE CLARITY
CONTROL
-
Reduces or
eliminates undesirable
sig-
nals
displayed
near the
water's surface. Also
called "5CC".
THERMOCUNE
-Alayer
ofwatercaused
bythe
meeting
of warm and
cool
layers
of water. The
thermocline
provides
the
temperature
mostfish
prefer.
TRANSDUCER
-
The element
of a sonar
system
that
converts the electri-
INTRODUCTION
When the Z-7200
Liquid
Crystal Graph (LCG)
is turned
on,
it will
automaticallyfind
and
displaythe
bottom
signal
and
othertargets.
As the
bottom
depth
changes,
the
Z-7200 will
automatically change
the
range
and
sensitivity
to
keep
the bottom
signal
on the
display.
If
desired,
the
only key
that needs
to be touched
is the ON
key.
However, disabling
the
automatic mode allows
manual
adlustment
of the Z-7200.
The Z-7200 is
nitrogen
filled and
sealed for
complete
waterproof
protection.
The
liquid crystal display
and
keyboard
are
backlighted
for
easy
use at
night.
PIus,
ft's covered
by
a full one
year warranty.
This
includes
all
parts
and
labor for one
year
from the date of
purchase.
To
get
started with
your
Z-7200,
first
read the installation section.
This
iswhere it all
begins,
and
Improper
installation
can cause
problems
down
the road. After
you've
read
these instructions
and Installed
your
Z-7200,
read
the rest of this
manual in detail. The
more
you
know when
you
get
to
the
water,
the more
your
Z-7200 will do for
you.
INSTALLATION
Mounting
Install the Z-7200
in
any
convenient location,
provided
there is
clearance
when tilted forthe
bestviewing angle.
Holes in the bracket base
allow
wood screw or
through
bolt
mounting.
Attach the bracket to
aluminum
panelswith
sheet metal
screws. Place
a
piece
of
plywood
onthe
back of
thin
fiberglass panels
to secure the
mounting
hardware. Make
certain
there is
enough
room behind
the unit to attach
the
power
and
transducer cables.
You can
route the
power
and
transducer cables
through
the
7/8"
hole In the base of
the
gimbal
bracket.
Then
pass
them
through
a hole in
the
mounting
surface.
The smallest
hole that will
pass
one connector
through
is
3/4H
Pass
the transducer connector
and cable
up
through
the
hole and
gimbal
bracket.
Then
push
the
power
cable wire down
through
the bracket and dash.
After
routing
the cables,
fill the hole with silicone
rubberadhesive
(RN).
Offsetthe bracketto
coverthe
majority
of the hole.
