PRINCIPLE OF OPERATION
The FCV-582L determines the distance between its transducer and underwater objects
such as fish, lake bottom or seabed and displays the results on its screen. It does this by
utilizing the fact that an ultrasonic wave transmitted through water travels at a nearly constant speed of 4800 feet (1500 meters) per
second. When a sound wave strikes an underwater object such as fish or sea bottom,
part of the sound wave is reflected back toward the source. Thus by calculating the time
difference between the transmission of a
sound wave and the reception of the reflected
sound wave, the depth to the object can be
determined.
The entire process begins in the display unit.
Transmitter power is sent to the transducer as
a short pulse of electrical energy. The electrical signal produced by the transmitter is converted into an ultrasonic signal by the
transducer and transmitted into the water. Any
returning signals from intervening objects
(such as a fish school) are received by the
transducer and converted into an electrical signal. The signals are then amplified in the amplifier section, and finally, displayed on the
screen.
The picture displayed is made up of a series
of vertical scan lines, one for each transmission. Each line represents a snapshot of what
has occurred beneath the boat. Series of snapshots are accumulated side by side across the
screen, and the resulting contours of the bottom and fish between the bottom and surface
are displayed.

bottom conditions. The lower the frequency
of the pulse, the wider the detection area.
Therefore, the 50 kHz frequency is useful for
general detection and judging bottom condition.

Graphic display
There are two types of graphic displays:
graphic display 1 and graphic display 2 , and
you can select which one to display on the
SYSTEM MENU1.
The graphic display 1 provides analog and
digital displays of cross-track error (XTE),
course and bearing. It is useful for monitoring progress toward a waypoint. The XTE
scale in the center of the display , graduated in
increments of 0.1 nm, shows cross-track error, the dird/Xion and distance the boat is off
course. In the example below the XTE marker
(red) shows the boat is off course by 0.2 nm
starboard. Therefore you would steer left by
the same distance to return to course.
Resetting trip distance indication on graphic
displays
The trip distance indication displays the distance the boat has traveled. To reset the indication to zero, press both the [▲] and [▼] keys
together until the indication reads zero. (The
indication can also be reset by pressing one
of the arrow keys, in which case it takes about
five seconds.) Note that the trip indication is
reset to zero whenever the power is turned
off.
The graphic display 2 mainly provides analog speed meter and cross-track error indication.

1.6 Selecting Display Range
The basic range and range shifting functions
used together give you the means to select the
depth you can see on the screen. The basic
range can be thought of as providing a “window” into the water column and range shifting as moving the “window” to the desired
depth. Note that the RANGE control is inoperative in automatic operation. (See the next
page for details.)
Shift
Display
Figure 1-15 Range and display shift concept
The basic range may be shifted with the [+]
and [–] keys. The shift display window , which
appears when the [+] or [–] key is operated,
shows current shift amount. Note that the
SHIFT keys and RANGE control are inoperative in automatic operation.
SHIFT 0m
Figure 1-17 Shift display
Note: The maximum shift range is 2500 feet
(500 m). However, the actual range will depend on underwater conditions. In the worst
case echoes will not appear.
1.7 Adjusting the Gain
The GAIN control adjusts the sensitivity of
the receiver . Adjust the control so that a slight
amount of noise remains on the screen. Generally, use a higher gain setting for greater
depths and a lower setting for shallower waters. Note that the GAIN control is inoperative in automatic operation.
Basic range selection
The basic range may be selected by the
RANGE control from the eight ranges shown
in the table below.

1.8 Automatic Operation
1.9 Selecting Picture Advance
Automatic operation is useful when you are
preoccupied with other tasks and do not have
time to adjust the display.
How it works
The automatic function automatically selects
the proper gain and range scale according to
depth. It works as follows:
• The range changes automatically to locate
the bottom on the lower half of the screen.
It jumps to one step shallower range when
bottom echoes reach a halfway point of the
full scale from top and to one step deeper
range when they come to the lower edge
of the scale.
• The gain is automatically adjusted to dis-
play the bottom echo in reddish-brown (default color arrangement).
• Clutter level (on the User menu), which
suppresses low level noise, is automatically
adjusted.
Two types of automatic modes
Two types of automatic modes are available:
cruising and fishing. Cruising is for tracking
the bottom; fishing is for searching fish
schools. Since cruising uses a higher clutter
rejection setting than fishing, it is not recommended for fish detection – weak fish echoes
may be deleted by clutter rejection.
Speed
The picture advance speed determines how
quickly the vertical scan lines run across the
screen. When selecting a picture advance
speed, keep in mind that a fast advance speed
will expand the size of the fish school horizontally on the screen and a slow advance
speed will contract it.
1. Press the ZOOM and SIG LEV keys together. The following display appears.

2.6 Echo Offset
TVG (Time Varied Gain) compensates for
propagation attenuation of the ultrasonic
waves. It does this by equalizing echo presentation so that fish schools of the same size
appear in the same density in both shallow
and deep waters. In addition, it reduces surface noise. Note that if the TVG level is set
too high short range echoes may not be displayed.
1. Turn on the power while pressing any key.
2. Press the ZOOM key three times. The
start-up screen appears and shortly thereafter the TVG SELECT display appears.

INTERPRETING THE DISPLAY
3.1 Zero Line
The zero line (sometimes referred to as the
transmission line) represents the transducer’s
position, and moves off the screen when a
deep phased range is used.
Zero
line
Shift
Figure 3-1 Zero line
3.2 Fish School Echoes
Fish school echoes will generally be plotted
between the zero line and the bottom. Usually the fish school/fish echo is weaker than
the bottom echo because its reflection property is much smaller compared to the bottom.
The size of the fish school can be ascertained
from the density of the display.
3.3 Bottom Echo
Echoes from the bottom are normally the
strongest and are displayed in reddish-brown
color (in default color arrangement) but the
color and width will vary with bottom composition, water depth, frequency, sensitivity,
etc.
In a comparatively shallow depth, a high gain
setting will cause a second or sometimes a
third or a fourth echo to be displayed at the
same interval between them below the first
echo trace. This is because the echo travels
between the bottom and the surface twice or
more in shallow depths.
The color of the bottom echo can be used to
help determine the density of the bottom materials (soft or hard). The harder the bottom,
the wider the trace. If the gain is set to show
only a single bottom echo on mud, a rocky
bottom will show a second or third bottom return. The range should be chosen so the first
and second bottom echoes are displayed when
bottom hardness is being determined.

3.4 Surface Noise/Aeration
Surface noise
When the waters are rough or the boat passes
over a wake, surface noise may appear near
the zero line. As surface turbulence is acoustically equivalent to running into a brick wall,
the bottom echo will be displayed intermittently . Similar noise sometimes appears when
a water temperature difference (thermocline)
exists. Different species of fish tend to prefer
different temperature zones, so the thermocline may be useful to help identify target
fish. 200 kHz tends to show shallow thermoclines better than 50 kHz.
In rough waters the display is occasionally interrupted due to below-the-ship air bubbles
obstructing the sound path. This also occurs
when the boat makes a quick turn or reverses
movement. Lowering the picture advance
speed may reduce the interruption. However,
reconsideration of the transducer installation
may be necessary if the interruption occurs
frequently.
