SAFETY INSTRUCTIONS  
WARNING  
WARNING  
ELECTRICAL SHOCK HAZARD  
Do not open the equipment.  
Radio Frequency  
Radiation Hazard  
Only qualified personnel  
should work inside the  
equipment.  
The radar antenna emits electromagnetic  
radio frequency (RF) energy which can be  
harmful, particularly to your eyes. Never  
look directly into the antenna aperture from  
a close distance while the radar is in  
operation or expose yourself to the trans-  
mitting antenna at a close distance.  
Turn off the radar power  
switch before servicing the  
antenna unit. Post a warn-  
ing sign near the switch  
indicating it should not be  
turned on while the antenna  
unit is being serviced.  
Distances at which RF radiation levels of  
100 and 10 W/m2 exist are given in the  
table below.  
Prevent the potential risk of  
being struck by the rotating  
antenna and exposure to  
RF radiation hazard.  
Note: If the antenna unit is installed at a  
close distance in front of the wheel house,  
your administration may require halt of  
transmission within a certain sector of  
antenna revolution. This is possible - Ask  
your FURUNO representative or dealer to  
provide this feature.  
Wear a safety belt and hard  
hat when working on the  
antenna unit.

SYSTEM CONFIGURATIONS  
All NavNet products incorporate a “network circuit board” to integrate each NavNet product  
on board through an optional LAN cable (Ethernet 10BASE-T). Each NavNet product is  
assigned an IP address to enable transfer of images between other NavNet products. For  
example, video plotter pictures can be transferred to a radar and vice versa. Pictures  
received via the NavNet may be adjusted at the receiving end.  
The number of display units which may be installed depends on the number of network  
sounder connected. For a system incorporating three or more products, a “hub” is required  
to process data.  
For one network sounder: one radar and three plotters, or four plotters  
For two network sounder: one radar and two plotters, or four plotters

WHAT IS WAAS?  
WAAS, available in North America, is a provider in the worldwide SBAS (Satellite  
Based Augmentation System) navigation system. SBAS provides GPS signal  
corrections to SBAS users, for even better position accuracy, typically better  
than three meters. Two more SBAS providers are also currently under  
development, MSAS (Multi-Functional Satellite Augmentation System) for Japan  
and EGNOS (Euro Geostationary Navigation Overlay Service) for Europe. All  
provides will be compatible with one another, thus providing “seamless” position  
fixes to SBAS users.

are expected to have initial operations capability from the times shown above.)  
During this developmental period, which may last for several years, there is no  
guarantee of the accuracy, integrity, continuity, or availability of the SBAS signal.  
Furuno will accept no responsibility for the use of the signal for other than the  
above stated purpose. It is the user’s responsibility to exercise common  
prudence and navigational judgment while using the SBAS signal.

The simulation display, for use by service technicians for demonstration  
purposes, provides simulated operation to help acquaint you with the many  
features your unit has to offer. It allows you to view and control a simulated  
plotter, radar and sounder picture, without position-fixing equipment, network  
radar or a network sounder. Most controls are operative, thus you may practice  
setting destination, enter waypoints, measure range and bearing to a target, etc.

Note: If the auto setting does not provide satisfactory tuning, ask your dealer  
how to re-adjust tuning.  
2.4  
Adjusting the Gain  
The [GAIN] key adjusts the gain sensitivity of the radar receiver. It works in a  
manner similar to that of volume control of a broadcast receiver, which amplifies  
received signals.  
The proper setting is such that the background noise is just visible on the screen.  
If your gain setting is too low, weak echoes may be missed. On the other hand,  
excessive gain yields too much background noise; strong targets may be missed  
because of the poor contrast between desired echoes and the background noise  
on the display.  
To adjust the receiver sensitivity, transmit on long range, and then do the  
following:

To suppress rain clutter from heavy storms or scattered rain clutter, adjust the  
FTC.  
In addition to reducing clutter, the FTC can be used in fine weather to clarify the  
picture when navigating in confined waters. However, with the circuit active the  
receiver is less sensitive. Therefore, turn off the FTC, by setting it for “0”, when  
its function is not required.  
1. Press the [GAIN] key.  
2. Press the FTC soft key to show the FTC window.  
3. Rotate the [ENTER] knob to adjust. The range of adjustment is 0-100(%). Do

2.5  
Reducing Sea Clutter  
2.5.1  
How the A/C SEA works  
Echoes from waves can be troublesome, covering the central part of the display  
with random signals known as “sea clutter”. The higher the waves and the higher  
the antenna above the water, the further the clutter will extend. Sea clutter may  
affect radar performance because real targets are sometimes hidden by the  
echoes of small waves. (See the left-hand figure in the figure below.) When sea  
clutter masks the picture, adjust the A/C SEA to reduce the clutter.  
The A/C SEA reduces the amplification of echoes at short ranges (where clutter  
is the greatest) and progressively increases amplification as the range increases,  
so amplification will be normal at those ranges where there is no sea clutter.  
Sea clutter at  
screen center  
A/C SEA adjusted;

2.5.2  
Adjusting the A/C SEA  
A/C SEA should be adjusted so that the clutter is broken up into small dots, and  
small targets become distinguishable.

A/C RAIN settings.  
6. Press the [GAIN] key on the front panel or RETURN soft key to finish.  
2.6  
Reducing Precipitation Clutter  
The vertical beamwidth of the antenna is designed to see surface targets even  
when the ship is rolling. However, by this design the unit will also detect  
precipitation clutter (rain, snow, hail, etc.) in the same manner as normal targets.  
Precipitation clutter shows as random dots on the screen.  
2.6.1  
Adjusting the A/C RAIN  
When echoes from precipitation mask solid targets, adjust the A/C RAIN to split  
up these unwanted echoes into a speckled pattern, making recognition of solid  
targets easier.

Radar interference may occur when near another shipborne radar that is  
operating in the same frequency band as your radar. Its on-screen appearance  
looks like many bright dots either scattered at random or in the form of dotted  
lines extending from the center to the edge of the display. Interference effects  
are distinguishable from normal echoes because they do not appear in the same  
place on successive rotations of the scanner.  
Be sure to turn off the interference rejector when no interference exists – weak  
targets may be missed.

2.19 Echo Stretch  
Normally, the reflected echoes from long range targets appear on the display as  
weaker and smaller blips even though they are compensated by the radar’s  
internal circuitry. The echo stretch function magnifies these small blips in all  
ranges. Two types of echo stretch are available: ES LOW which stretches  
echoes in bearing direction and ES HIGH which stretches them in both range  
and bearing directions.

2.20 Echo Averaging  
The echo average feature, which requires a Model 1800/1900 series network  
radar, effectively suppresses sea clutter. Echoes received from stable targets  
such as ships appear on the screen at almost the same position during every  
rotation of the antenna. On the other hand, unstable echoes such as sea clutter  
appear at random positions.  
To distinguish real target echoes from sea clutter, echo average performs  
scan-to-scan correlation. Correlation is made by storing and averaging echo  
signals over successive picture frames. If an echo is solid and stable, it is  
presented in its normal intensity. Sea clutter is averaged over successive scans  
resulting in the reduced brilliance, making it easier to discriminate real targets  
from sea clutter.  
To properly use the echo average function, it is recommended to first suppress  
sea clutter with the A/C SEA control and then do the following:  
1. If not displayed, press the [HIDE/SHOW] key to display the radar soft keys.  
2. Press the SIGNAL PROC. soft key.  
3. Press the E. AVG soft key to select desired echo averaging.  
OFF: No averaging  
LOW: Helps distinguish targets from sea clutter and suppresses brilliance  
of unstable echoes.  
MED: Distinguishes small stationary targets such as navigation buoys.  
HIGH: Stably displays distant targets.  
4. Press the RETURN soft key to finish.  
The display shows EAV L, EAV M or EAV H when echo averaging is on.

2. RADAR OPERATION  
2.26 ARP, TTM Operation  
When the radar source is an ARP-equipped Model 1800/1900 series network  
radar, you can manually and automatically acquire and track ten targets. Once a  
target is acquired automatically or manually it is automatically tracked within 0.1  
to 32 nm. If the FURUNO heading sensor PG-1000 is used, the data sentence  
“RMC” is necessary.  
Alternatively, you can display the tracks of other ships by receiving the data  
sentence TTM (Tracked Target Message) via the NETWORK or NMEA port on  
the display unit. However, targets cannot be acquired.  
Note: When using your unit as remote display, you cannot change the range of  
the main radar at the remote display. For the target acquisition, set the  
range individually.  
Usage precautions for ARP  
CAUTION  
The plotting accuracy and response of  
this auto plotter meets IMO standards.  
Tracking accuracy is affected by the  
following:  
WARNING  
No one navigational aid should be relied  
upon for the safety of vessel and crew.  
The navigator has the responsibility to  
check all aids available to confirm  
position. Electronic aids are not  
a substitute for basic navigational  
principles and common sense.  
Tracking accuracy is affected by course  
change. One to two minutes is required to  
restore vectors to full accuracy after an  
abrupt course change. (The actual  
amount depends on gyrocompass  
specifications.)  
The amount of tracking delay is inversely  
proportional to the relative speed of the  
target. Delay is on the order of 15-30  
seconds for high relative speed; 30-60  
seconds for low relative speed.  
This auto plotter automatically tracks an  
automatically or manually acquired radar  
target and calculates its course and  
speed, indicating them by a vector. Since  
the data generated by the auto plotter  
are based on what radar targets are  
selected, the radar must always be  
optimally tuned for use with the auto  
plotter, to ensure required targets will not  
be lost or unwanted targets such as sea  
returns and noise will not be acquired  
and tracked.  
Display accuracy is affected by the  
following:  
Echo intensity  
A target does not always mean a land-  
mass, reef, ships or other surface vessels  
but can imply returns from sea surface  
and clutter. As the level of clutter changes  
with environment, the operator should  
properly adjust the A/C SEA, A/C RAIN  
and GAIN controls to be sure target  
echoes are not eliminated from the  
radar screen.

2.26.8 CPA/TCPA alarm (ARP)  
When the predicted CPA of any target becomes smaller than a preset CPA alarm  
range or its predicted TCPA less than a preset TCPA alarm limit, an audio alarm  
sounds and the speaker icon appears (in red). In addition, the target plot symbol  
of the offending target changes to a triangle and flashes together with its vector.  
You may silence the audio alarm with the [CLEAR] key. Press the [ALARM] key  
and the message “COLLISION ALARM” appears. Press the CLEAR ALARM soft  
key to acknowledge the alarm. The flashing of the triangle plot symbol continues  
until you intentionally terminate tracking of the target. The ARP continuously  
monitors the predicted range at the Closest Point of Approach (CPA) and  
predicted time to CPA (TCPA) of each track to own ship.  
This feature helps alert you to targets which may be on a collision course with  
own ship. However, it is important that gain, A/C SEA, A/C RAIN and other radar  
controls are properly adjusted and the ARP is set up so that it can track targets  
effectively.  
CPA/TCPA alarm ranges must be set up properly taking into consideration the  
size, tonnage, speed, turning performance and other characteristics of own ship.  
CAUTION  
The CPA/TCPA alarm should never be  
relied upon as the sole means for detect-  
ing the risk of collision. The navigator is  
not relieved of the responsibility to keep  
visual lookout for avoiding collisions,  
whether or not the radar or other plotting  
aid is in use.

2.27 Interpreting the Radar Display  
2.27.1 General  
Minimum and maximum ranges  
Minimum range  
The minimum range is defined by the shortest distance at which, using a scale of  
1.5 or 0.75 nm, a target having an echoing area of 10 m2 is still shown separate  
from the point representing the antenna position. It is mainly dependent on the  
pulselength, antenna height, and signal processing such as main bang  
suppression and digital quantization. It is best to use the shortest possible range  
as long as the clarity and definition of the picture remain good.  
Maximum range  
The maximum detecting range of the radar, Rmax, varies considerably  
depending on several factors such as the height of the antenna above the  
waterline, the height of the target above the sea, the size, shape and material of  
the target, and atmospheric conditions.  
Under normal atmospheric conditions, the maximum range is equal to the radar  
horizon or a little shorter. The radar horizon is longer than the optical one by  
about 6% because of the diffraction property of the radar signal. Rmax is given  
in the following equation.  
Rmax= 2.2 x ( h1 + h2 )  
where  
Rmax: radar horizon (nautical miles)  
h1:  
h2:  
antenna height (m)  
target height (m)  
Radar horizon  
Optical horizon  
Radar horizon  
For example, if the height of the antenna above the waterline is 9 meters and the  
height of the target is 16 meters, the maximum radar range is;  
Rmax= 2.2 x ( 9 + 16 ) = 2.2 x (3 + 4) = 15.4 nm  
It should be noted that the detection range is reduced by precipitation (which  
absorbs the radar signal).

2. RADAR OPERATION  
Radar resolution  
There are two important factors in radar resolution (discrimination): bearing  
resolution and range resolution.  
Bearing resolution  
Bearing resolution is the ability of the radar to display the echoes received from  
two targets, which are at the same range and close together, as separate targets.  
Bearing resolution is directly proportional to the antenna length, and inversely  
proportional to the radar's wavelength.  
Range resolution  
Range resolution is the ability to display the echoes received from two targets,  
which are on the same bearing and close to each other, as separate targets.  
Bearing accuracy  
One of the most important features of the radar is how accurately the bearing of  
a target can be measured. The accuracy of bearing measurement basically  
depends on the narrowness of the radar beam. However, the bearing is usually  
taken relative to the ship’s heading, and thus, proper adjustment of the heading  
marker at installation is an important factor in ensuring bearing accuracy. To  
minimize error when measuring the bearing of a target, select a range which will  
put the target as far out to the edge of the radar screen as possible.  
Range measurement  
Measurement of the range to a target is also a very important function of the  
radar. There are three means of measuring range: the fixed range rings, the  
trackball and the variable range marker (VRM). The fixed range rings appear on  
the screen with a predetermined interval and provide a rough estimate of the  
range to a target. The trackball is rolled to place the cursor on the leading edge  
of the target. Range and bearing to the target is shown at the bottom right-hand  
corner of the display. The variable range marker’s diameter is increased or  
decreased so that the marker touches the inner edge of the target, allowing the  
operator to obtain more accurate range measurements.

2. RADAR OPERATION  
2.27.2 False echoes  
Occasionally echo signals appear on the screen at positions where there is no  
target or disappear even if there are targets. False target situations may be  
recognized, however, if you understand why they are displayed. Typical false  
echoes are shown below.  
Multiple echoes  
Multiple echoes occur when a transmitted pulse returns from a solid object like a  
large ship, bridge, or breakwater. A second, a third or more echoes may be  
observed on the display at double, triple or other multiples of the actual range of  
the target as shown below. Multiple reflection echoes can be reduced and often  
removed by decreasing the gain (sensitivity) or properly adjusting the [A/C SEA]  
control.

Sidelobe echoes  
Every time the radar pulse is transmitted, some radiation escapes on each side  
of the beam. This stray RF is called a “sidelobe.” If a target exists where it can  
be detected by the sidelobes as well as the main lobe, the side echoes may be  
represented on both sides of the true echo at the same range. Sidelobes show  
usually only on short ranges and from strong targets. They can be reduced  
through careful reduction of the gain or proper adjustment of the A/C SEA  
control.

Virtual image  
A relatively large target close to your ship may show at two positions on the  
screen. One of them is the true echo directly reflected by the target and the other  
is a false echo which is caused by the mirror effect of a large object on or close  
to your ship as shown in the figure below. If your ship comes close to a large  
metal bridge, for example, such a false echo may temporarily be seen on the  
screen.

2. RADAR OPERATION  
2.27.3 SART (Search and Rescue Transponder)  
A Search and Rescue Transponder (SART) may be triggered by any X-Band (3  
cm) radar within a range of approximately 8 nm. Each radar pulse received  
causes it to transmit a response which is swept repetitively across the complete  
radar frequency band. When interrogated, it first sweeps rapidly (0.4 µs) through  
the band before beginning a relatively slow sweep (7.5 µs) through the band  
back to the starting frequency. This process is repeated for a total of twelve  
complete cycles. At some point in each sweep, the SART frequency will match  
that of the interrogating radar and be within the pass band of the radar receiver.  
If the SART is within range, the frequency match during each of the 12 slow  
sweeps will produce a response on the radar display, thus a line of 12 dots  
equally spaced by about 0.64 nautical miles will be shown.  
When the range to the SART is reduced to about 1 nm, the radar display may  
show also the 12 responses generated during the fast sweeps. These additional  
dot responses, which also are equally spaced by 0.64 nm, will be interspersed  
with the original line of 12 dots. They will appear slightly weaker and smaller  
than the original dots.

2. RADAR OPERATION  
General procedure for detecting SART response  
1. Use the range scale of 6 or 12 nm as the spacing between the SART  
responses is about 0.6 nm (1125 m) to distinguish the SART.  
2. Turn off the automatic clutter suppression (if applicable).  
3. Turn off the Interference Rejector.  
General remarks on receiving SART  
SART range errors  
When responses from only the 12 low frequency sweeps are visible (when the  
SART is at a range greater than about 1 nm), the position at which the first dot is  
displayed may be as much as 0.64 nm beyond the true position of the SART.  
When the range closes so that the fast sweep responses are seen also, the first  
of these will be no more than 150 meters beyond the true position.  
Radar bandwidth  
This is normally matched to the radar pulselength and is usually switched with  
the range scale and the associated pulselength. Narrow bandwidths of 3-5 MHz  
are used with long pulses on long range and wide bandwidths of 10-25 MHz with  
short pulses on short ranges.  
Any radar bandwidth of less than 5 MHz will attenuate the SART signal slightly,  
so it is preferable to use a medium bandwidth to ensure optimum detection of  
the SART.  
Radar sidelobes  
As the SART is approached, sidelobes from the radar antenna may show the  
SART responses as a series of arcs or concentric rings. These can be removed  
by the use of the [A/C SEA] control although it may be operationally useful to  
observe the sidelobes as they may be easier to detect in clutter conditions and  
also they will confirm that the SART is near to the ship.  
Gain  
For maximum range SART detection the normal gain setting for long range  
detection should be used, that is, with background noise speckle visible.

2. RADAR OPERATION  
A/C SEA control  
For optimum range SART detection, this control should be set to the minimum.  
Care should be exercised as wanted target in sea clutter may be obscured. Note  
also that in clutter conditions the first few dots of the SART response may not be  
detectable, irrespective of the setting of the anti-clutter sea control. In this case,  
the position of the SART may be estimated by measuring 9.5 nm from the  
furthest dot back towards own ship.  
Some sets have automatic/manual anti-clutter sea control facilities in which case  
the operator should switch to manual.  
A/C RAIN control  
This should be used normally (to break up areas of rain) when trying to detect a  
SART response which, being a series of dots, is not affected by the action of the  
anti-clutter rain circuitry. Note that racon responses, which are often in the form  
of a long flash, will be affected by the use of this control.  
Some sets have automatic/manual anti-clutter rain control facilities in which case  
the operator should switch to manual.  
Note: This SART information is excerpted from IMO SN/Circ 197 Operation of  
Marine Radar for SART Detection.  
2.27.4 Racon (Radar Beacon)  
A racon is a radar transponder which emits a characteristic signal when triggered  
by a ship’s radar (usually only the 3 centimeter band). The signal may be emitted  
on the same frequency as that of the triggering radar, in which case it is  
superimposed on the ship's radar display automatically.  
The racon signal appears on the PPI as a radial line originating at a point just  
beyond the position of the radar beacon or as a Morse code signal (see figure  
below) displayed radially from just beyond the beacon.

The XTE monitor, located below the compass rose, shows the distance you are  
off course and the direction to steer to return to course. The own ship marker  
moves according to direction and distance off course. It is shown in black when  
the amount of cross-track error is within the XTE monitor range and yellow when  
it is over. An arrow appears at the right or left side of the XTE monitor and it  
shows the direction to steer to return to intended course. It is shown in red when  
you should steer left, and green when you should steer right. In the example on  
the previous page you would steer right to return to course. To maintain course,  
steer the vessel so the own ship marker stays at the center of the XTE monitor.

In drawing the own ship track, first the ship’s position fed from position-fixing  
equipment is stored into the unit’s memory at an interval of time or distance. A  
shorter interval provides for 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.

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 999 waypoints into which you can enter position information. You  
may enter a waypoint five ways: at own ship position, at MOB position (see page  
1-14 for details), by cursor, by range and bearing, and through the waypoint list  
(manual input of latitude and longitude).

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 optional Network Sounder ETR-6/10N/30N you can show  
video 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 network sounder. 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.

LF picture  
The sounder uses ultrasonic pulses to detect bottom conditions. The lower the  
frequency of the pulse, the wider the detection area. Therefore, the low  
frequency is useful for general detection and judging bottom condition.  
HF picture  
The higher the frequency of the ultrasonic pulse the better the resolution.  
Therefore, the high frequency is ideal for detailed observation of fish school.

Automatic Sounder Operation  
Automatic sounder operation is useful when you are preoccupied with other  
tasks and do not have the 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 the depth. It works as follows:  
The range changes automatically to locate the bottom on the lower half of the  
screen. The range jumps to one step shallower range when the bottom  
echoes reach a half way point of the full scale from the top and to one step  
deeper range when they come to the lower edge of the 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  
4.3.3  
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.  
How to enable automatic sounder operation  
1. If not displayed, press the [HIDE/SHOW] key to show the sounder soft keys.

Manual Sounder Operation  
Manual operation is useful for observing fish schools and bottom using a fixed  
gain setting.  
The gain, range and range shift 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.

4.14 Changing Pulse Repetition Rate  
Pulse repetition rate can be changed. Normally, the highest rate (20) is used.  
When in shallow waters, second reflection echoes may appear between surface  
and actual bottom echo. In this case lower the PRR level. The option “SPD  
SENSING PRR” means the ship’s speed dependent mode, where the PRR  
changes automatically with ship’s speed (required speed input.) For further  
information about the ship’s speed dependent mode, see page 4-18.  
1. Press the [MENU] key to open the menu.  
2. Press the SOUNDER MENU soft key.  
3. Select PRR LEVEL.  
4. Press the EDIT soft key to open the setting window.  
5. Use the trackball to select the rate for repetition.  
6. Press the ENTER soft key followed by the [MENU] key to close the menu.  
Too small setting reduces the number of pulse repetition. This may cause a  
problem to search fish schools. Select “20” unless multistage reflections appear  
on the display.

4.15 Interpreting the Sounder Display

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  
Zero line  
4.15.2 Bottom echo  
Echoes from the bottom are normally the strongest and are displayed in  
reddish-brown, 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.

4.15.3 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.

4.15.4 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.

Geodetic Datum Geodetic datum is a reference for geodetic  
survey measurements consisting of fixed latitude,  
longitude and azimuth values associated with a  
defined station of reference. You must have the  
correct geodetic datum selected in your plotter so  
that it will reference the correct point on the chart  
for a given latitude and longitude. Although  
WGS-84 is now the world standard, other  
See Appendix for full list.  
categories of charts still exist. Refer to Appendix  
for a full list of geodetic datum.

Position  
When the DOP or receiving condition is unfavorable,  
Smoothing the GPS fix may change greatly, even if the vessel is  
not moving. This change can be reduced by smoothing  
the raw GPS fixes. A setting between 000 to 999 is  
available. The higher the setting the more smoothed  
the raw data. If the setting is too high, the response  
time required to show a change of latitude and  
longitude will be too long. This is especially noticeable  
if the vessel is moving fast. Increase the setting if the  
GPS fix changes randomly.  
Spd/Cse  
During position fixing, ship’s velocity (speed and  
0-999 seconds  
Smoothing course) is directly measured by receiving GPS satellite  
signals. The raw velocity data may vary too much  
depending on receiving conditions and other factors.  
You can reduce this random variance by increasing the  
smoothing. The higher the smoothing setting, the more  
the raw data will be averaged. If this setting is high, the  
response to speed and course changes will slow. For  
no smoothing, enter all zeroes.  
GPS  
Speed  
Calculation of ETA is based on average ship’s speed  
over a given period. If the period is too long or too

Every GPS satellite is broadcasting abnormal satellite  
number(s) in its Almanac, which contains general  
orbital data about all GPS satellites, including those  
which are malfunctioning. Using this information, the  
GPS receiver automatically eliminates any  
malfunctioning satellite from the GPS satellite  
schedule. However, the Almanac sometimes may not  
contain this information. If you hear about a

TVG  
TVG (Time Varied Gain) compensates 0-9  
(HF,LF)  
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.
