lVlounting—Portable
Units
Only
Installing
the Batteries
The Z-5000
portable requires
two
six-volt lantern
batteries. To install
them,
turn the
battery
box
upside
down and release the
two latches on
the
front of the
compartment. Open
it
and slide the two
batteries into the
case with the
spring
terminals
against
the
battery
board.
(Note:
the
battery
board
may
need to be
placed
in
its slot before
installing
the
batteries.)
The
battery
board is
specially
designed
to assure
proper
contact with the
terminals,
regardless
of
their
position.
Close the
compartment
lid
and latch the case.
Plug
the
power
cable
into the back
of
the sonar unit and turn it on.
The Z-5000 should
begin working.
If
it
isn't
check
the batteries for
proper voltage.
Most of the
complaints
received about
portable
units result from
using
stale batteries. All
carbon
batteries have
a limited shelf life. Be sure
the batteries
you buy
are fresh
stock.
Always
remove
them from the
compartment
before
storing
the
unit
as dead ones
can leak and corrode the
plating
on the
battery
board.

FISH SIGNALS
The
signals displayed
on the
Z-5000
by
fish can be identified
by
various
shaped markings
in
certain
patterns,
as
opposed
to random
marks created
by
noise,
or the
solid,
continuous
markings
made
by
the
bottom.
Individual fish
can,
at
times,
be
distinguished
by
a
characteristic arch
that
separates
them from their
stationary
surroundings.
The reason for
this is shown below. The distance to a fish
when it moves into the
sonar's cone of sound
is shown as "A"
Figure
14. When the
fish has
moved into the center of the
cone,
the distance to it will be
shorter, "B",
and as it
moves out of the
cone,
the distance will increase
again
as
shown
in "C".
If a
partial
arch
occurs most of the time on
your
unit
(the
mark curves
up,
but not
back
down,
or
vice-versa)
it could be the
transducer is not
pointed
straight
down. If
the transducer is mounted on
the
transom,
adjust
it until
the fish show the distinctive arch. This
may
take some trial
and error until
the correct
mounting
is achieved.
