SAFETY INSTRUCTIONS
WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Turn off the radar power
switch before servicing the
antenna unit. Post a warn-
ing sign near the switch
indicating it should not be
turned on while the antenna
unit is being serviced.
Prevent the potential risk of
being struck by the rotating
antenna and exposure to
RF radiation hazard.
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 equip-
ment is emitting smoke or fire.
Continued use of the equipment can cause
fire or electrical shock.
Use the proper fuse.
Fuse rating is shown on the power cable.
Use of a wrong fuse can result in damage
to the equipment.
Keep heater away from equipment.
Heat can alter equipment shape and melt
the power cord, which can cause fire or
electrical shock.
A warning label is attached to the
processor unit. Do not remove the label.
If the label is missing or damaged,
contact a FURUNO agent or dealer.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.
Name: Warning Label (1)
Type: 86-003-1011-0
Code No.: 100-236-230
WARNING
Radio Frequency
Radiation Hazard
The radar antenna emits electromagnetic
radio frequency (RF) energy which can be
harmful, particularly to your eyes. Never
look directly into the antenna aperture from
a close distance while the radar is in
operation or expose yourself to the trans-
mitting antenna at a close distance.
Distances at which RF radiation levels of
100 and 10 W/m
2
exist are given in the
table below.
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.

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 processor 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 sounders: one radar and two plotters (or four plotters)

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

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

5. When the radar source is the Model 1800-BB/1900-BB series, sea clutter
and rain clutter can be automatically rejected. Press the D: A/C AT ON/OFF
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 E: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.
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 C:A/C RAIN soft key to show the A/C RAIN window.

4. Press the [GAIN] key on the front panel or E:RETURN soft key to finish.
Adjusting the FTC (When the radar source is the M1700 series radar)
To suppress rain clutter from heavy storms or scattered rain clutter, adjust the
FTC.
In addition to reducing clutter, the FTC can be used in fine weather to clarify the
picture when navigating in confined waters. However, with the circuit active the
receiver is less sensitive. Therefore, turn off the FTC, by setting it for “0”, when
its function is not required.
1. Press the [GAIN] key.
2. Press the D:FTC soft key to show the FTC window.
3. Rotate the [ENTER] knob to adjust. The range of adjustment is 0-100. Do not
overadjust the FTC – weak target echoes may be missed.

2.20 Echo Averaging
The echo average feature, which requires a Model 1800-BB/1900-BB 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 A:SIGNAL PROC. soft key.
3. Press the B:E. AVG soft key to select desired echo averaging.
OFF: No averaging
LOW: Helps distinguish targets from sea clutter and suppresses brilliance
of unstable echoes.
MED: Distinguishes small stationary targets such as navigation buoys.
HIGH: Stably displays distant targets.
4. Press the E:RETURN soft key to finish.

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 (G2) IN or
G1 (G2) OUT is changed to G1 (G2) ***.
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.

2.26 ARP, TTM Operation
When the radar source is an ARP-equipped Model 1800/1900 series network
radar, you can manually and automatically acquire and track ten targets. Once a
target is acquired automatically or manually it is automatically tracked within 0.1
to 32 nm. If the FURUNO heading sensor PG-1000 is used, the data sentence
“RMC” is necessary.
Alternatively, you can display the tracks of other ships by receiving the data
sentence TTM (Tracked Target Message) via the NETWORK or NMEA port on
the processor unit. However, targets cannot be acquired.
Note: When using your unit as a remote display, you cannot change the range of
the main radar at the remote display. In this case, to acquire a target, 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 land-
mass, reef, ships or other surface vessels
but can imply returns from sea surface
and clutter. As the level of clutter changes
with environment, the operator should
properly adjust the A/C SEA, A/C RAIN
and GAIN controls to be sure target
echoes are not eliminated from the
radar screen.
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)

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

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

2. RADAR OPERATION
2-45
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.

2.27.2 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.
Own ship
Target
True

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.

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

2.27.3 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.
offered by Busse-Yachtshop.de
2. RADAR OPERATION
2-50
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.

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. An arrow appears at the right or left side of the XTE monitor and it
shows the direction to steer to return to intended course. It is shown in red when
you should steer left, and green when you should steer right. In the example on
the previous page you would steer right to return to course. To maintain course,
steer the vessel so the own ship marker stays at the center of the XTE monitor.

3.1.3 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 the 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.

3.6.4 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.
Track plotting method
Track may be plotted by time or distance. The default setting is “time.”
1. Press the [MENU] key followed by the A:CHART SETUP and B:TRACKS &
