FOREWORD
A Word to the Owner of the GD-1700/1710 Series
Video Plotter
FURUNO Electric Company thanks you for purchasing the GD-1700/1710 Series 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 plotter 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.

Features
The 1700 series work within our new product-network system called the “NavNet.” Each
product has an IP address to communicate with NavNet compatible products within the
network, using TCP/IP protocol through an Ethernet 10BASE-T network.
The main features are as follows:
• Three models are available:
GD-1700: Monochrome LCD
GD-1700C: Color LCD
GD-1710C: High-precision color LCD
• Bright 7” screen visible even under direct sunlight.
• User-friendly operation with combination of discrete keys, soft keys and cursor pad.
• Accepts FURUNO and NavCharts™ (NAVIONICS) charts, or C-MAP NT/NT+ charts
(C-MAP), depending on specification.
All names mentioned are registered trademarks of their respective companies.
• Fast chart redraw.
• Built-in NavNet interface circuit board.
• 12-channel GPS Receiver GP-310B with highly accurate position fixing optionally
available, GP-320B with WAAS capability.
• User programmable function keys.
• Radar picture available with connection to NavNet compatible radar.
• Video sounder picture available with connection of the optional Network Sounder
ETR-6/10N or ETR-30N.
• Optional memory card interface unit CU-200.
ix
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
providers will be compatible with one another, thus providing “seamless” position
fixes to SBAS users. The illustration below shows the coverage area. (Accuracy
may be affected when using a GEO satellite not within your current location.)

At the time of this software release, SBAS is still under development (Providers
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. Users are
reminded that the SBAS has not been commissioned for use in safety of life
applications (SOLAS) and must be turned to the "OFF" position on any SOLAS
vessels.

Simulation Display
The simulation display, which is 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, etc.
The “SIM” icon ( I M ) appears when any simulation mode is active.

(solid on the monochrome model) triangle, which moves with ship’s course,
shows own ship’s course.
The water temperature and depth graphs, which require appropriate sensors,
show the latest 10 minutes of water temperature and depth data. The range of
the depth graph is 50 feet and it is automatically adjusted with depth.

Reading the XTE (cross-track error) monitor
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. (On the monochrome model it flashes when the amount of cross-track
error is more than the XTE monitor range.) 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. (For the color model the arrow 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.
Soft keys
EDIT XT-LMT: Sets the range for XTE monitor scale. See the procedure below
for how to set.

Highway display
The highway display, shown in combination displays, provides a graphic
presentation of ship’s track along intended course. It is useful for monitoring
ship’s progress toward a waypoint. The own ship marker shows relation between
ship and intended course. The XTE monitor shows the direction and amount
your vessel is off course – the arrow shows the direction to steer to return to
your course and the numeric the distance you are off course. Using the figure
below as an example, you would steer right 0.009 nm to return to course. To
maintain course, steer the vessel so the own ship marker stays aligned with the
intended course line.

Your ship’s track is plotted on the screen using navigation data fed from
position-fixing equipment. This section shows you what you can do with track,
from turning it on or off to changing its plotting interval. Own ship’s track is
displayed in the default setting and on the color model it is red.

Track plotting method and interval for own ship track
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 (page
1-15), by cursor, by range and bearing, and through the waypoint list (manual
input of latitude and longitude).
2.8.1

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.

Note: Reciprocal setting and canceling of destination is available by outputting
the data sentence ZDA from the NavNet unit connected to the navigator.
2.10.1
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

When you steer to avoid an obstacle or the vessel drifts, you may go off your
intended course, as in Line 1 in the figure below. Also, if you don’t need to return
to the original course, you can go directly to the next waypoint, as in Line 2 in
the figure below. In these cases, use the restart function to restart navigation.

ARRVL ALM CRCL: Automatically switches the TO waypoint when the boat
comes within the arrival alarm range. For how to set the arrival alarm, see the
paragraph “2.11.2 Arrival alarm.”
MANUAL: The destination waypoint may be manually switched by using the
RESTART soft key (see page 2-50). This function is operative when “1 POINT” is

Adjusting the Gain
The [GAIN] key adjusts the sensitivity of the radar receiver. It works in a manner
similar to the 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
3.5.1
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.

radar echoes. The range of adjustment is 0-100. Do not overadjust the A/C
SEA – weak target echoes may be missed.

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.
3.6
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.
3.6.1
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.

3. RADAR OPERATION
3.6.2
Adjusting the FTC
To suppress rain clutter from heavy storms or scattered rain clutter, adjust the
FTC, which is available with the Model 1700 series network radar. The FTC
splits up these unwanted echoes into a speckled pattern, making recognition of
solid targets easier.
Note: 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.

The heading line indicates the ship's heading in all presentation modes. It is a
line from the own ship position to the outer edge of the radar display area and
appears at zero degrees on the bearing scale in head-up mode; it changes its
orientation in the north-up, course-up and true motion modes with ship’s
movement.
The north marker appears as a short dashed line. In the head-up and course-up
modes the north marker moves around the bearing scale as the ship’s heading
moves.

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 rejection circuit when no interference exists –
weak targets may be missed.

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.

Echo Averaging
The echo average feature, available with connection of 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.

Guard Alarm
The guard alarm allows the operator to set the desired range and bearing for a
guard zone. When ships, islands, landmasses, etc. violate the guard zone, an
audio alarm sounds and the offending target blinks to call the operator’s
attention.
CAUTION
• The alarm should not be relied upon as
the sole means for detecting possible
collision situations.
• A/C SEA, A/C RAIN and GAIN controls
should be properly adjusted to be sure
the alarm system does not overlook
target echoes.

3. RADAR OPERATION
The equipment then searches for targets inside the guard zone to determine
guard alarm type. If a target is found inside the guard zone, the guard zone type
becomes an “Outward guard alarm,” and any target exiting the guard zone will
trigger the audio alarm. If no target is found, the guard zone type becomes an
“Inward guard alarm,” and any targets entering the guard zone will trigger the
audio alarm. The guard alarm type is shown as G1(G2) IN or G1(G2) OUT.
Note 1: When the radar range is less than the guard zone range, “G1 (2) IN” or
“G1 (2) OUT” changes to “G1 (2) ***.” The guard alarm function is not
available while this indication appears.
Note 2: If the network radar is set to standby while the guard alarm is active, the
guard alarm is cancelled. The guard alarm is redisplayed when the
radar is set to transmit again.

ARP, TTM Operation
With an ARP-equipped Model 1800/1900 series network radar as the radar
source, 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.
However, targets cannot be acquired.
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.
3-34
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)

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 (red on the color model) appears. 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.

Interpreting the Radar Display
3.26.1
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).
3-44
3. 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
cursor 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 cursor pad is operated 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.
3-45
3. RADAR OPERATION
3.26.2
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.

non-detecting sector or blind spot may be produced. Within this sector, targets
can not be detected.

3. RADAR OPERATION
3.26.3
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.

3. 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.
3-49
3. 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.
3.26.4
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.

VIDEO SOUNDER OPERATION
With connection of the optional network sounder 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.

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.

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 depth. It works as follows:
• Range changes automatically to locate the bottom on the lower half of screen.
The range 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 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.

The sounder section has five conditions which generate visual and aural alarms:
bottom alarm, fish alarm (bottom lock), fish alarm (normal) and water
temperature alarm (temperature sensor required). For 1700C/1710C, note that
the alarm icon is red when an alarm setting is violated, and changes to
background color when the [CLEAR] key or CLEAR ALARM soft key is pressed.
The color does not change when another alarm is violated.
You may set up the sounder alarms on the ALARM menu, which may be
displayed by pressing the [ALARM] key.

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 4-17.

Zero line
The zero line (sometimes referred to as the transmission line) represents the
transducer’s position.

4.15.2
Bottom echo
Echoes from the bottom are normally the strongest and are displayed in
reddish-brown (color model) or darkest tone (monochrome model) but the color
(tone on the monochrome model) 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 (tone for monochrome model) 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. However, reconsideration of the transducer
installation may be necessary if the interruption occurs frequently.

Description
GPS uses UTC time. If you would rather
use local time, enter the time difference
between it and UTC. Use the +< - ->- soft
key to switch from plus to minus and vice
versa.
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 categories of charts
still exist. Refer to Appendix for a full list of
geodetic datum.
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.
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.

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

schedule. However, the Almanac sometimes
may not contain this information. If you hear

Description
Settings
TVG
(LF, HF)
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.
0-9
Echo Offset
(LF, HF)
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. The default setting for both 200 kHz and 50
kHz is zero.
-50 - +50
Bottom Level
(LF, HF)
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 displayed.
-100 - +100
KP Pulse
Selects source of keying pulse.

Smoothing
Smoothes echoes to present stable display. The higher the
setting the greater the smoothing.

TLL Output
Outputs current position to plotter where it is marked with TLL
mark. Use a soft key to output TLL.
ON, OFF
STC (HF, LF)
(For ETR-30N
only)
Adjusts STC level for the high and low frequencies, and is useful for
suppressing surface noise. The setting range is 0-10; the higher the setting
the greater the extent or suppression. Setting 10 suppresses noise up to
several meters. Turn off the STC when there is no noise on the screen,
otherwise weak echoes may be missed.
-10 - +10
FREQ. ADJ. (HF,
LF) (For
ETR-30N only)
Interference from other acoustic equipment operating nearby or other
electronic equipment on your boat may show itself on the display. You may
suppress these type of interference by adjusting frequency.

Depth calibration: If you desire the depth readout to show the distance
between ship’s draft and bottom (rather than transducer and bottom), set
ship’s draft here. Enter a plus or minus value.
Acoustic speed calibration: Sets the speed of sound used by the network
sounder. Normally no adjustment is required, however if echoes are returning
too slow or too fast adjust the value as appropriate. This is only used if water
salinity is at an extreme level. Under normal circumstances, do not adjust.

MAINTENANCE,
TROUBLESHOOTING
This chapter provides information necessary for keeping your unit in good
working order and remedying simple problems.
WARNING
Do not open the equipment.
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
Item
Check point
Remedy
Display unit
connectors
Check for tight connection.
Tighten loosened connectors.
LCD
The LCD will, in time,
accumulate a coating of
dust which tends to dim the
picture.
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.
Ground terminal
Check for tight connection
and corrosion.
Clean or replace ground wire as
necessary.
7-1
7. MAINTENANCE, TROUBLESHOOTING
7.2
Replacement of Fuse
The fuse on the power cable protects the equipment from reverse polarity of the
ship’s mains and equipment fault. If the fuse blows, find out the cause before
replacing it. Use the correct fuse (10A for 12 V, 5A for 24 V). Using the wrong
fuse will damage the equipment and void the warranty.
CAUTION
Use the proper fuse.
Use of a wrong fuse can cause fire or
damage the equipment.
7.3
Replacement of Batteries
Battery on circuit board
A battery 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.
