SAFETY INSTRUCTIONS
WARNING
WARNING
Radio Frequency
Radiation Hazard
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
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 transmitting antenna at a close distance.
Turn off the radar power
switch before servicing the
antenna unit. Post a warning 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.
MODEL
Serious injury or death can
result if someone falls from
the radar antenna mast.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Turn off the power immediately if water
leaks into the equipment or the equipment is emitting smoke or fire.
Continued use of the equipment can cause
fire or electrical shock.

FOREWORD
A Word to the Owner of the Model 1800C/1900C Series
Marine Radar, GD-1900C Color Video Plotter
FURUNO Electric Company thanks you for purchasing the Model 1800C/1900C Series
Marine Radar, GD-1900C Color Video Plotter. We are confident you will discover why the
FURUNO name has become synonymous with quality and reliability.
For over 50 years FURUNO Electric Company has enjoyed an enviable reputation for
quality and reliability throughout the world. This dedication to excellence is furthered by our
extensive global network of agents and dealers.
Your equipment is designed and constructed to meet the rigorous demands of the marine
environment. However, no machine can perform its intended function unless properly
installed and maintained. Please carefully read and follow the operation and maintenance
procedures set forth in this manual.
We would appreciate feedback from you, the end-user, about whether we are achieving our
purposes.
Thank you for considering and purchasing FURUNO.
The example screens shown in this manual may not match the screens you see on your
display. The screen you see depends on your system configuration and equipment settings.
Note: SBAS is currently in the developmental phase and SBAS providers are expected to
have initial operations capability as shown below. During the developmental phase the
accuracy, integrity, continuity, or availability of the SBAS signal cannot be guaranteed.
Therefore, any position data should be verified against other sources to confirm reliability.
WAAS (N. America): Wide Area Augmentation System, 2003
EGNOS (Europe): European Geostationary Navigation Overlay Service, 2004
MSAS (Japan): MTSAT Satellite based Augmentation System, 2005
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 providers will be compatible with one another, thus providing
“seamless” position fixes to SBAS users. For coverage area, see “SBAS Coverage Area” in
the Appendix. Unless otherwise noted, this manual uses “WAAS” when referring to any
SBAS provider.

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.
A NavNet system may consist of up to four display units and one network sounder. For a
system incorporating three or more products, a “hub” is required to process data.

Overview of display unit controls
The radar, video plotter, sounder and chart systems are operated with the
controls of the display unit (and the remote controller). Ten keys are labeled and
they provide the function shown on their labels. The five soft keys provide
various functions according to current operating mode. The [ENTER] knob
mainly functions to register selections on the menu and adjust the EBL, VRM
and gain. The trackball’s main function is to move the cursor across the screen.
When you correctly execute an operation, the unit generates a beep. Invalid
operation causes the unit to emit three beeps.

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.
The simulation icon ( I M ) appears when any simulation mode is active.
To start the simulation display;
1. Press the [MENU] key.
2. Press the SYSTEM CONFIGURATION, SYSTEM SETUP and SIMULATION

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:

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.

select ON or OFF as appropriate. When turned on, it overrides A/C SEA and
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.
1. Press the [GAIN] key.
2. Press the A/C RAIN soft key to show the A/C RAIN window.

Rejecting Radar Interference
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.

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:

attention.
CAUTION
• The alarm should not be relied upon as

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
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.
• 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.
• A target does not always mean a landmass, 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.
2-34
CAUTION
The plotting accuracy and response of
this auto plotter meets IMO standards.
Tracking accuracy is affected by the
following:
• 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.
Display accuracy is affected by the
following:
• Echo intensity
• Radar transmission pulsewidth
• Radar bearing error
• Gyrocompass error
• Course change (own ship or target)

The ARP can acquire up to ten targets automatically by setting an automatic
acquisition area. When automatic acquisition is selected after acquiring targets
manually, only the remaining capacity for targets may be automatically acquired.
For example, if seven targets have been manually acquired, three targets may
be automatically acquired.

What is a vector?
A vector is a line extending from a tracked target which shows estimated speed
and course of the target. The vector tip shows an estimated position of the target
after the selected vector time elapses. It can be useful to extend the vector
length (time) in order to evaluate the risk of collision with any target.

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 detecting 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.
Follow the steps shown below to set the CPA/TCPA alarm range:
1. Press the [MENU] key followed by the ARP SETUP soft key.

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:
antenna height (m)
h2:
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).
2-44
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.
2-45
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.
True

Own ship
Multiple

Multiple echoes
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.

Funnels, stacks, masts, or derricks in the path of the antenna block the radar

can not be detected.

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.

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.
2-49
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.

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).
3.8.1

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.

Navigation
This section shows you how to get to a desired destination by “quick points,”
waypoints, port services and routes.
Note: Reciprocal setting and canceling of destination is available by outputting
the data sentence ZDA from the NavNet unit connected to the navigator.
3.10.1
Navigating to a “quick point”
The “quick point” feature allows you to navigate to point(s) without retaining the
data indefinitely in your unit’s memory.
Selecting quick point entry method
You need to tell your unit how to set the quick point: 1 POINT, 35 POINTS (up to
35 points) or 35PTS/PORT SVC. (For how to navigate to points/port services
see “3.10.2 Navigating to ports, port services” on page 3-45.)
1. Press the [MENU] key.
2. Press the PLOTTER SETUP soft key.
3. Use the trackball to select SET GOTO METHOD, then press the EDIT soft

or GOTO WPT soft key.
A solid light-blue line with arrows connects between own ship and destination,
which is marked as “” for cursor-selected location or waypoint name in
case of waypoint. This line shows the shortest course to the destination. Arrows
on the line show the direction to follow to get to the quick point. Range and
bearing from own ship to the destination appear at the top of screen. The quick
point location is saved to the waypoint list as waypoint “QP01.”

VIDEO SOUNDER OPERATION
With connection of the optional Network Sounder ETR-6/10N 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.

Dual-frequency display
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.

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
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

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.

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.

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.

Smoothing
When the DOP or receiving condition is
unfavorable, 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.

Smoothing
During position fixing, ship’s velocity (speed and
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.

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.
If the on-screen echo level
appears to be too weak or too
strong and the level cannot be
adjusted satisfactorily with the gain
control, adjust echo offset to
compensate for too weak or too
strong echoes.
If the depth indication is unstable
in automatic operation or the
bottom echo cannot be displayed
in reddish-brown by adjusting the
gain control in manual operation,
you may adjust the bottom echo
level detection circuit, for both 50
kHz and 200 kHz, to stabilize the
indication. Note that if the level is
set too low weak echoes may be
missed and if set too high the
depth indication will not be

Hazardous voltage which can
cause electrical shock exists
inside the equipment. Only
qualified personnel should
work inside the equipment.
7.1
Preventive Maintenance
Regular maintenance is important for optimum performance. A maintenance
program should be established and should at least include the items shown in
the table below.
Maintenance program

Check for tight connection
and corrosion.
The LCD will, in time,
accumulate a coating of
dust which tends to dim
the picture. Wipe LCD
lightly with soft cloth to
remove dust.
Wipe the LCD carefully to prevent scratching,
using tissue paper and an LCD cleaner. To
remove dirt or salt deposits, use an LCD
cleaner, wiping slowly with tissue paper so as
to dissolve the dirt or salt. Change paper
frequently so the salt or dirt will not scratch
the LCD. Do not use solvents such as thinner,
acetone or benzene for cleaning.
Clean or replace ground wire as
necessary.
Replacement of Battery
A lithium battery (Type CR2450-F2 ST2L, Code No. 000-144-941) fitted on a
circuit board inside the display unit preserves data when the equipment is turned
off, and its life is about three years. When its voltage is low the battery icon ( )
appears at the top of the display. When the icon appears, contact your dealer to
request replacement of the battery.
