For
example, the 9
key has a small label
beneath the number nine that
says "LIGHT". If
you press
the 9
key by itself, the X-3 thinks that you want
the number 9.
However,
if
you press
the 2nd key first, then press
the nine
key, the X-3 will turn on the
lights in the
display.

knowledge of the water temperatures
various fish prefer, and in which
they usually remain, helps you get the most
from
your X-3. To find the dif-
ferent
temperatures,
a
surface temperature meter, such as the
LDT-3000 is a valuable aid to your fishing.
This unit
provides an
extremely quick response
to identifying
the desired surface water
temperatures
for various
species.
The temperature
of water in the lake is seldom constant from top
to bot-
tom. Layers
of different
temperatures 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 important
to fishermen because
they
are areas where fish are active. Many times
bait
fish will be above the thermocline while
larger game
fish will sus-
pend in or just
above it
The X-3 can detect this invisible
temperature layer in the water, but the
sensitivity
will probably have to be turned up
to see it
CHART SPEED
When the X-3 is first turned
on, the chart
speed runs at a
pre-determined
speed.
If a higher
speed is desired,
press
and hold the FAST key in the
chart section of the
keyboard
until it runs at the
desired speed.
To slow
the display,
press and hold the SLOW
key. Whenever either of these keys
are pressed,
the
sensitivity
bar at the
top of
the
display
will change
to a
dashed line. This now represents
the chart speed. If
you press and hold
the FAST key, foräxample, the bar will start
moving
to the right, signifying
that the chart speed is increasing.
There are thirty two
steps of chart
speed. By holding either the FAST or SLOW
keys, the
display can be
speeded up or slowed down. When the horizontal
barreaches the far
right side of the
screen,
the chart speed
is at its maximum value. The X-3
will "chirp" signifying
that the maximum chart speed
has been reached.

At
times it is desirable to stop or "freeze"
the
display
to examine an echo.
Pressing
the STOP/RESUME
key once wil freeze the display.
While the
display is
stopped,
the
very top of the
surface line will flash on and off
to
signify
that the unit is in the freeze mode. Pressing
STOP/RESUME
again
will start the display moving
at the last chart speed setting.
[2ND]
2ND KEY
The X-3 has many
different
functions, but only
a limited amount of
space
for
keys. Therefore,
some of the keys have more than one function. The
key's primary
function is
printed very large, while the secondary
function
is printed underneath with small letters of a different color. The
key in the
middle of the
bottom row labeled 2nd must be used to access the
secondary
functions of the keys.
