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.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Distances at which RF radiation levels of
100 and 10 W/m2 exist are given in the
table below.
Immediately turn off the power at the
switchboard if the equipment is emitting
smoke or fire.
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.
Continued use of the equipment can cause
fire or electrical shock. Contact a FURUNO
agent for service.
Keep heater away from equipment.
A heater can melt the equipment's power
cord, which can cause fire or electrical
shock.

FOREWORD
Features
The MODEL1722/1722C/1723C 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 10 Base-T network.
The main features are
! Bright 7” screen visible even under direct sunlight.
MODEL1722 series: Monochrome LCD
MODEL1722C series: Color LCD
MODEL1723C series: High-precision color LCD
! User friendly operation with combination of discrete keys, soft keys and cursor pad.
! Accepts FURUNO and Nav-charts™ (NAVIONICS) or C-MAP NT/NT+ charts (C-MAP).
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 or GP-320B with WAAS (see the note in below.)
! User programmable function keys.
! Video sounder picture available with connection to optional network sounder.
! ARP function (when connecting with MODEL1833/1833C series)
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
For two network sounder: one radar and two 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.

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.
Note: This manual uses “WAAS” when referring to any SBAS provider.

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.
The simulation icon ( I M ) appears when any simulation mode is active.

7. Press the [MENU] key to close the menu.
Note: If the auto setting does not provide satisfactory tuning, see the installation
manual for how to adjust tuning.
2.4
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.
2-2
2. RADAR OPERATION
To adjust the receiver gain, transmit on long range, and then do the following:
1. Press the [GAIN] key. The last-used “adjustment window” is displayed. In the

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 is 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.

2. RADAR OPERATION
5. When the radar source is the Model 1833/C series radar, A/C SEA and
A/C RAIN can be automatically adjusted. Press the A/C AT soft key to 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 rain
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. This
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.

2. RADAR OPERATION
2.6.2
Adjusting the FTC
To suppress rain clutter from heavy storms or scattered rain clutter, adjust the
FTC. 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.
FTC is available when the radar source is the MODEL1722/1723C series radar.
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. The
heading line 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 depending on the ship orientation in north-up,
course-up and true motion modes.
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.
To temporarily erase the heading line and north marker, press the RADAR
DISPLY soft key followed by the HL OFF soft key. Release the key to redisplay
the markers.

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

Echo Averaging
The echo average feature, available with selection of a Model 1833/C series
network radar as radar source, 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.

becomes an “Outward guard alarm”, and any target exiting, the guard zone will
trigger an 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 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 (G2) IN” or
“G1 (G2) OUT” changes to “G1 (G2) ***.” The guard alarm function is

ARP (option), TTM operation
When the radar source is ARP-equipped Model 1833/C series network radar,
you can manually and automatically acquire and track 10 targets. Once a target
is acquired automatically or manually it is automatically tracked within 0.1 to 32
nm. When the FURUNO heading sensor PG-1000 is connected, RMC sentence
(NMEA) is required for true heading data.
Alternatively, you can display the tracks of other ships by receiving the data
sentence “TTM” through 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.
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)

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, which you may silence with the [CLEAR] key. In addition, the target plot
symbol of the offending target changes to a triangle and flashes together with its
vector. 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 target to own ship.
Provided that this feature is used correctly, it will help prevent the risk of collision
by alerting you to threatening targets. 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:

Interpreting the Radar Display
2.26.1
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.
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. Generally, there are two means of measuring range: the fixed range rings
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 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
2.26.2
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.
True

Target
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 sidelobe. If a target exists where it can be
detected by the side lobes as well as the main lobe, the side echoes may be
represented on both sides of the true echo at the same range. Sidelobes appear
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.

2. RADAR OPERATION
Virtual image
A relatively large target close to your ship may be shown 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.

Shadow sectors
Funnels, stacks, masts, or derricks in the path of the antenna block the radar
beam. If the angle subtended at the antenna is more than a few degrees, a
non-detecting sector or blind spot may be produced. Within this sector, targets
can not be detected.

2. RADAR OPERATION
2.26.3
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.

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 side lobes
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.
2.26.4
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.

In drawing the own ship track, first the ship’s position fed from a navigation
receiver 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
(page3-61), 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.

reciprocal setting and canceling of destination is available by using ZDA
sentenceReferring to “6.5 Outputting Data Through the Network”.
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: 1POINT, 35POINTS (up to
35 points) or 35PTS/PORT SVC. (For how to navigate to points/port services

3. Depending on the selection you made at step 1 press GOTO CURSOR or
GOTO WPT soft key.
A solid line (light-blue on the MODEL1722C/1723C series) with arrows connects
between own ship and destination, which is marked as “QP<01>” for
cursor-selected location or waypoint name in case of waypoint. Arrows on the
line show the direction to follow to get to the point. Range and bearing from own
ship to the destination appear at the top of screen. The quick point is saved to
the waypoint list as waypoint “QP01.”

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 1722C/1723C series, 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.

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.

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.

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.

Chart offset
In some instances position may be off by a few seconds. For example, the
position of the ship is shown to be at sea while it is in fact moored at a pier. You
can compensate for this error by offsetting chart position as shown in the
procedure below. You can execute the procedure from any display mode.
1. Show the plotter display and press the [MENU] key followed by the CHART

Geodetic Datum
Note: 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 lat / lon. Although WGS-84
is now the world standard, other categories of charts still
exist. refer to Appendix for a full list of geodetic datum.
Position Smoothing
When the DOP or receiving condition is unfavorable, the 0-999 sec
GPS fix may change greatly, even if the vessel is not
moving in water. 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 Lat and LON
will be too long. this is especially noticeable if the vessel
is moving fast. This is especially noticeable at high ship’
speeds. Increase the setting to increase the amount of
averaging applied to the GPS fix.

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 variance by increasing the smoothing. Like with
latitude and longitude smoothing, the higher the speed
and course 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 zeros.

Satellite
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 malfunctioning satellite from another source, you
can disable it manually. Enter satellite number (two digits,

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 HF and LF 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 LF and HF, 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.

installation manual.)
Smoothing
Smooths echoes to present stable display. The higher
the setting the greater the smoothing.
SM1-SM4, OFF
TLL Output
Outputs cursor position to external equipment.
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.
0-10
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.
