3.1.2 Compass display
The compass display, displayed at the bottom half of the screen in the
plotter/compass combination display, provides steering information. The
compass rose shows two arrows: the solid triangle shows own ship’s course
(heading) and the hollow inverted triangle shows the bearing to destination
waypoint. When own ship’s course is changed, the hollow inverted triangle
moves with course change. Ship’s course and waypoint direction are updated
every second and other information is updated every 15 seconds.
The water temperature and depth graphs shows latest 10 minutes of temperature
and depth data. The range of the depth graph is 50 feet and it is automatically
adjusted with depth.

3.8.4 Track plotting method and interval for own ship track
In drawing the own ship track, first the ship’s position (fed from the blackbox GPS
unit or DGPS/GPS receiver) is stored into the unit’s memory at an interval of time
or distance. A shorter interval provides better reconstruction of the track, but the
storage time of the track is reduced. When the track memory becomes full, the
oldest track is erased to make room for the latest.
Track plotting method
Track may be plotted by time or distance interval and the default setting is “time.”
1. Press the [MENU] key followed by CHART SETUP and TRACK & MARK

3.10 Waypoints
In navigation terminology, a waypoint is a particular location on a voyage whether
it be a starting, intermediate or destination point. A waypoint is the simplest piece
of information your equipment requires to get you to a destination, in the shortest
distance possible.
This unit has 1000 waypoints into which you can enter position information. There
are five methods by which you can enter a waypoint: at own ship position, at
MOB position, by cursor, by range and bearing, and through the waypoint list
(manual input of latitude and longitude).

3.11 Routes
Often a trip from one place to another involves several course changes, requiring
a series of route points (waypoints) which you navigate to, one after another. The
sequence of waypoints leading to the ultimate destination is called a route. Your
unit can automatically advance to the next waypoint on a route, so you do not
have to change the destination waypoint repeatedly.
You can store up to 200 routes, and a route may have 35 waypoints.

4. VIDEO SOUNDER OPERATION
With connection of the blackbox echo sounder you can display echo sounder
images on the display.
4.1 Principle of Operation
The video sounder determines the distance between its transducer and
underwater objects such as fish, lake bottom or seabed and displays the results
on 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 (transducer).
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 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. A 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.

4. VIDEO SOUNDER OPERATION
4-4
50 kHz picture
The sounder uses ultrasonic pulses to detect 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.
200 kHz picture
The higher the frequency of the ultrasonic pulse the better the resolution.
Therefore, the 200 kHz frequency is ideal for detailed observation of fish school.

4.3 Automatic Sounder Operation
Automatic sounder operation is useful when you are preoccupied with other tasks
and do not have time to adjust the display.
4.3.1 How the automatic sounder works
The automatic sounder function automatically selects the proper gain, range
scale and clutter suppression level according to depth. It works as follows:
• Range changes automatically to locate the bottom on the lower half of screen.
It jumps to one step shallower range when bottom echoes reach a half way
point of the full scale from top and to one step deeper range when they come to
the lower edge of scale.
• The gain is automatically adjusted to display the bottom echo in reddish brown
(default color arrangement).
• Clutter, which suppresses low level noise, is automatically adjusted.
4.3.2 Types of automatic sounder modes
Two types of automatic sounder modes are available: CRUISING and FISHING.
CRUISING is for tracking the bottom, and FISHING is for searching fish schools.
CRUISING uses a higher clutter rejection setting than FISHING therefore it is not
recommended for fish detection - weak fish echoes may be erased by the clutter
suppression circuit.
4.3.3 How to enable automatic sounder operation
1. Press the MODE/D. BOX soft key

4.4 Manual Sounder Operation
Manual operation is useful for observing fish schools and bottom using fixed gain
setting.
The gain, range and range shifting functions used together give you the means to
select the depth you can see on 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.
4.4.1 Selecting the manual mode
1. Press the MODE/D. BOX soft key to show the mode/freq window.
2. Select OFF (MANUAL).
3. Press the RETURN soft key.
4.4.2 Selecting display range
Press the [RANGE +] or [RANGE -] key to select a range.
4.4.3 Adjusting the gain
Normally, set the gain to the point where excessive noise does not appear on
screen. Use a higher gain setting for greater depths and a lower setting for
shallow waters.
Gain too high Gain proper Gain too low
Examples of proper and improper gain
Press the [GAIN] key to show the gain window, and use the cursor pad to set the
gain. Current level is shown above the bar. Press the RETURN key or the [GAIN]
key to finish.

4.12.6 When an alarm setting is violated...
When an alarm setting is violated the buzzer sounds, and the speaker icon
appears at the bottom of the screen. (The speaker icon is displayed until all
alarms have been acknowledged on the alarm menu display.) You can silence the
buzzer with the [CLEAR] key, however the buzzer will sound whenever the alarm
setting is violated.
To see which alarm(s) has been violated;
1. Press the [ALARM] key. The offending alarm is shown in the ALARM
INFORMATION window.

4.14 Interpreting the Sounder Display
4.14.1 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.

4.14.2 Bottom echo
Echoes from the bottom are normally the strongest and are displayed in reddish-
brown color 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.

4.14.3 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.

4.14.4 Surface noise/Aeration
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.
