Push the

(Caution
Keep
hands
away
from the
stylus
belt
and
stylus. High voltage
is
present.)
Insert a 6"-S"
long
screwdriver
with a 1/s" blade into the zero ad-
just
hole and rotate the control on
the circuit board until the zero line
is at the desired
position. (Note:
This
may
also be
adjusted
with
the unit turned OFF.
Adjust
the
control,
then remove the screw-
driver and turn
power
back ON.
Repeat
until the zero line is in
the desired
position.)
IV HOW TO READ
GRAPHS
"Arched
Signatures"
A
remarkable
advantage
of the
Z-15 is that it can record indi-
vidual fish with a characteristic
arched mark
that
separates
them
from their
stationary surroundings.
The reason for this is shown be-
low. The distance to a fish when it
moves into the sonar's cone of
sound is shown as 'A".
When the fish has moved to
the center of the
cone,
the dis-
tance to it will be
shorter, (line
"B"),
and as it moves out of the
cone,
the distance will increase
again
as shown in line "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
is because the trans-
ducer is not
pointed straight
down.
If
your
transducer is
mounted on
the
transom,
adjust
the transducer
until the fish show the distinctive
arched
signature.
This
may
take
some trial and error until the cor-
rect
mounting
is achieved.
Sharp,
well defined
signatures
will occur most often when the
Sensitivity
knob is set at the ¾
point,
or
higher. Remember,
that
there must be some movement
between the boat and the fish to
develop
the arched mark.
Usually
this means
trolling
at
very
slow
speeds
with the main
engine
in
gear
at minimum throttle
setting.
THERMOCLINES
The
temperature
of water in the
lake is seldom constant from
top
to bottom.
Layers
of different tem-
peratures
form,
and the
junction
of
a
warm and cool
layer
of water
is
called a thermocline. The
depth
and thickness of the thermocline
can
vary
with the season or time
of
day.
In
deep
lakes there
may
be two or
more,
at different
depths.
Thermoclines are
import-
ant to the fisherman because
they
are areas where fish
are active.
Many
times bait fish will be above
the
thermocline
while
larger game
fish
suspend just
below it.
Your
Eagle
Z-15 can
de-
tect this invisible
layer
in the
water,
but the
Sensitivity
knob wifl
probably
have to be set at the 1/a
point,
or
higher.
PAPER LOADING
CAUTION
High voltage
is
pre-
sent in the electronic section
when the unit is turned on.
1. TURN THE UNIT OFF.
2. Release both catches on the
top
of the case. Pull
out and
down on the
top
of
the
case
front to
expose
the
platen
as-
sembly. (See Figure 23.)
3. Move the
stylus
belt
DOWN,
to
position
the
marking stylus
on the back side of the
pla-
ten. NEVER move the belt
up
the
stylus may
be
damaged. (See Figure24.)
SPECIAL
NOTE: The
stylus
may
be
damaged
if the
platen
assembly
is
pulled
down un-
less the
stylus
has been
moved to the back side of the
platen.

END-OF-PAPER MARKER
The
graph paper
in the Z-15
has a red line
printed
at the bot-
tom of
the
paper
to
signify
when
there is
only
2 to 3 feet before the
end of the
paper.
ZERO ADJUST
Occasionally,
when
changing
the
stylus
or
stylus
belt,
the zero
line does not
print
at the same
place
near the
top
of the chart
paper.
Figure
21
A zero
adjust
control has been
placed
on the back inside wall of
the Z-15 near the
upper
left
hand corner so that the zero line's
position may
be
adjusted
on
the
paper.
Open
the case front and look
for the decal marked "ZERO AD-
JUST". You
may
have to
pull
