WARNING
Radio Frequency Radiation Hazard
The radar antenna emits electromagnetic radio frequency (RF) energy that 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. Distances at which RF radiation level of 100, 50 and 10 W/m2 are given in the table
below.

WARNING
Do not open the equipment.
The equipment uses high voltage that
can cause electrical shock. Refer any
repair work to a qualified technician.
Before turning on the radar, be sure
no one is near the antenna.
Prevent the potential risk of being
struck by the rotating antenna, which
can result in serious injury or death.
If water leaks into the equipment or
something is dropped into the
equipment, immediately turn off the
power at the switchboard.
WARNING
Fire or electrical shock can result.
If the equipment is giving off smoke
or fire, immediately turn off the
power at the switchboard.
Fire or electrical shock can result.
If you feel the equipment is acting
abnormally or giving off strange
noises, immediately turn off the
power at the switchboard and
contact a FURUNO service technician.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury
can result.
Make sure no rain or water splash
leaks into the equipment.
Fire or electrical shock can result if
water leaks into the equipment.
WARNING
Do not operate the equipment with
wet hands.
Electrical shock can result.
Keep objects away from the open-ntype antenna unit, so as not to
impede rotation of the antenna.
Fire, electrical shock or serious injury
can result.
Use the proper fuse.
Use of the wrong fuse can cause fire or
electrical shock.
Do not depend on one navigation
device for the navigation of the ship.
The navigator must check all aids
available to confirm position.
- The TT automatically tracks an
automatically or manually acquired
radar target and calculates its course
and speed, indicating them with a
vector. Since the data generated by
the TT depends on the selected radar
targets, the radar must be optimally
tuned for use with the TT, to ensure
required targets will not be lost or
unnecessary targets like sea returns
and noise will not be acquired and
tracked.
- A target is not always a landmass,
reef, ship, but can also be returns
from the sea surface and from clutter
As the level of clutter changes with
the environment, the operator must
correctly adjust the sea and rain
clutter controls and the gain control so
that the target echoes do not disappear from the radar screen.
Do not place liquid-filled containers
on or near the equipment.
Fire or electrical shock can result if a
liquid spills into the equipment.

1.2 Turning ON/OFF the Power, Transmission
1.2.1 Turning the power ON/OFF
Please note the following when using the radar.
Note: Make sure to use the [ ] key in the control unit when turning off the power of this radar. A
personal computer is used inside of the equipment. Turning off the power by using the breaker,
etc. instead of using the [ ] key may cause loss of data stored inside. In the worst situation, it
may prevent the machine from functioning properly. If you experience abnormal function, seek
for immediate service. Lost data are unrecoverable. Please backup your data periodically.
1. Open the cover at the left upper section of the control unit, press the [ ] key to turn the
radar switch on. When the slide switch of the monitor unit (MU-150HD or MU-190HD) is ON
(factory default), the power of the monitor unit is turned on automatically. When the switch is
turned OFF, press the [ / BRILL] key in the monitor unit to turn the power on. After the
power is turned on, the display on the screen changes in the order of FURUNO screen →
Machine type name screen → Getting ready screen. It takes approximately 1 and 1 ½ minutes
until the Getting ready screen appears. For FAR-1417, preheating of magnetron is completed
during this time. For FAR 1427, it starts counting down the remaining time (1 ½ minutes)
necessary for preheating magnetron. When getting ready appears on the screen, you can
start transmission. On the Getting ready screen, mark, fixed range ring, chart, TT target and
AIS target are not displayed. Left-click inside of the warning message box to erase the
warning message.
Warning message
Stant count down at
[01:19], it changes
to GETTING
READY.
01:19
Note 1: Do not turn the power on while USB memory is inserted in the control unit.
The GETTING READY screen does not show when USB memory is inserted.
Note 2: When ambient temperature is low, display on the screen moves slower.
2. Press the [ ] key in the control unit when turning the power off. The message “Shutting
down” appears at the center of the screen. Release the [ ] key immediately. The power
turns off in about 15 seconds.
Quick Start
When magnetron is sufficiently warmed up, you can start the transmission without waiting full
preheating time. Press the [ ] key again within 10 seconds after the power is turned off in error.
1.2.2 Switching between TRANSMISSION and GETTING READY
To start transmission, press the [Getting ready/Transmit] key while getting ready is displayed on
the screen. Radar echoes are displayed on the screen with the previously used settings of range,
brilliance, VRM, EBL and menu settings.
Each press of the [Getting ready/Transmit] key switches between getting ready and transmit.
Antenna is stopped at the time of Getting ready and starts rotating when transmission starts. Life
of magnetron shortens in proportion of transmission time. Keep the equipment in the Getting
ready state when there is no need for transmission.

1.7 Display Modes
This radar has the display modes of Head-up, Cursor gyro, Stern-up, Course-up, North-up and
True Motion. Each display mode is explained in Chapter 1.7.2. Display modes except Head-up
and Stern-up need heading signal. For True Motion, connection to GPS navigation equipment is
necessary. The true-view display function enables smooth rotation of radar echo in accordance
with own ship’s turns in Head-up, Cursor gyro and Stern-up modes only.
When Gyrocompass is connected
Gyrocompass readings and heading values in the information display area of this equipment
need to be matched accurately when receiving analog signal (Synchronization or Step signal)
from gyrocompass. (Setting method: Main menu → Echo → GC-10, See chapter 2.11.1.)
1.7.1 Selecting display mode
Press the [Select mode] key several times to select display mode necessary. Name of the
display mode currently being selected is displayed in the display mode box at the upper left
section on the screen.
Presentation mode box
Note 1: When heading signal is interrupted, the blinking message “Sensor Error Gyro” appears
in the alarm section in the information display area. Heading reading in the information display
area becomes “xxx°” and the North mark disappears and the monitor mode automatically
becomes the head-up mode. When heading signals are restored, select the monitor mode with
the [Select mode] key again.
Note 2: User can pre-set appropriate monitor mode to use. (See chapter 2.10.2.)
1.7.2 Description of display modes
Relative motion
In relative motion, own ship position is stationary on the screen to observe relative motion of
surrounding targets.
• Head-up
The head-up mode is a display in which the line
connecting the own ship and the top of the display
indicates own ship’s heading. Targets are displayed as if
they were viewed from the bridge. Therefore, this mode
is suitable for navigating through narrow channels and
crowded waters. On the other hand, target images may
fluctuate due to own ship’s turning and yawing.
A short line on the bearing scale is the north marker
indicating heading sensor north.
Noth maker
Heading line
• Cursor Gyro
It is the same screen as Head-up but bearing scale links to heading signal. The cursor gyro can
be used only when bearing sensor is connected to the radar. A failure of the bearing sensor will
cause the bearing scale to become the same as that in the head-up mode.
• Stern-up
The stern-up mode rotates the head-up mode picture 180° showing ship’s stern on top of the
display at all times.
• Course-up
The course-up mode is an azimuth-stabilized display in which a line connecting the center with
the top of the display indicating own ship’s intended course (harbor, destination, etc.) Own ship’s
heading moves in accordance with changes of its course indicating the initial bearing on the top
at all times to see errors between the set course and the current course. Target images do not
fluctuate at own ship’s turning and yawning to get stable images.

• North-up
The true north is at the top of the screen (0°) and the heading line changes its direction
according to the ship’s course. In this mode, fixed targets are shown as if they were viewed on a
chart. Targets on the screen do not fluctuate at own ship’s turning and yawning to get stable
images. This mode is suitable for ocean voyages, ship positioning and course monitoring, etc.
North marker
Heading line
True Motion
Like looking at charts, all fixed targets such as landmasses appear as stationary echoes and
own ship moves on the screen. When own ship reaches a point corresponding to 75% of the
radius of the display, own ship position is automatically reset to a point of 75% radius opposite to
the extension of the heading line passing through the display center to continue moving on the
screen. Own ship’s position can be automatically moved to 75% radius opposite to the course at
any time while in the true motion.

2. For automatic adjustment, roll the [Gain] knob according to sea condition to fine tune the
sensitivity. (Range: -50 ~ +50) For manual adjustment, roll the [Gain] knob to tune the
sensitivity. (Range: 0 ~ 100)
Note: For manual adjustment, adjust the gain control so that the background noise is just visible
on the screen. If the gain level is too low, weak echoes may be missed. On the other hand, if the
gain level is too high, the strong background noise may hide weak targets.
11
1.10 Rejecting Sea Clutter
Strong sea clutter occurs around own ship in bad weather due to strong reflection from sea
surface to prevent identification of targets on the screen. In such a case, use the sea clutter
rejection function to control sea clutter. Sea clutter can be rejected automatically or manually.
Sea clutter is rejected.
Sea clutter appears
at the center of the
screen.
Sea clutter rejection function
1. Press the [Sea clutter rejection] knob to select the method of sea clutter rejection. Each
press of the [Sea clutter rejection] knob switches between [Auto] and [Manual]. The control
sea clutter is automatically set at optimum level when the setting is [Auto].
-50
50
2. For automatic rejection, roll the [Sea clutter rejection] button according to sea conditions to
fine tune the setting. (Setting range: -50 ~ +50) To reduce sea clutter, increase the setting
value toward [+] and to increase sea clutter toward [-].
3. For manual rejection, roll the [Sea clutter rejection] knob while observing echoes on the
screen to reject sea clutter. (Setting range: 0 ~ 100)
Note: For manual adjustment, do not set the sea clutter rejection level too high. When the sea
clutter rejection level is too high, it may miss approaching targets. Normally set the level just so
weak sea clutter appears on the screen. Set the sea clutter rejection level at 0 (the minimum)
when there is no sea clutter appearing on calm sea surface.
1.11 Rejecting Precipitation Clutter
Radio waves transmitted from antenna are reflected on rain and snow to appear on the screen
as precipitation clutter. The function of precipitation clutter rejection is used when unwanted echo
covers up and hides targets. The precipitation clutter rejection is controlled in the similar way as
the sea clutter rejection but it becomes effective not only in near range but in longer range as
well. The higher the setting, the greater the anti-clutter effect becomes.
Unwaned echoes are displayed. Precipitation rejection
(Toward the starboard)

1.12 Automatic rejection of sea clutter and
precipitation clutter
When sea clutter and precipitation clutter cannot be removed fully, press the [Precipitation clutter
rejection] knob to select the unwanted echo rejection function. “Unwanted echo” is displayed at
the upper right section on the screen while the unwanted echo rejection function is working.
Notes on usage
• Echoes covering wide areas such as lands and islands may become smaller.
• Clutter or strong precipitation clutter more than necessary. In such a case, use the functions of
sea clutter rejection or precipitation clutter rejection to manually adjust the echo level at
optimum.
1.13 Deleting heading line temporarily
Heading line is displayed in all display modes and shows the own ship’s heading. Heading line
appears directly above own ship (0°) in the head-up mode and the cursor gyro mode. Heading
line appears directly under own ship (180°) in the stern-up mode. In the north-up, true motion
and course-up modes, heading line moves in accordance with own ship’s direction. Thickness
and color of heading lines can be changed in the [Mark] menu. (See page 2-31.)
To confirm small targets in heading direction press the [Delete heading line] to temporarily delete
the heading line. All the marks on the heading line and radar screen disappear and only targets
are displayed while this key is being pressed

1.15 Measuring range to target
There are three methods to measure range to target; fixed range ring, Cursor (See chapter
1.14.) and VRM (Variable Range Ring).
1.15.1 Using Fixed Range Ring
Fixed range ring (Concentric circle with own ship at its center) is used to make a rough
measurement. Fixed range ring interval is displayed at the upper left side on the screen.
Range between own ship and a target is estimated from the nearing fixed range ring
closest from the target by counting number of fixed range rings.
Note 1: Number of fixed range ring is determined in accordance with range selected. However,
the number can be selected manually. (See chapter 2.10.1.)
Note 2: Each left-click switches between ON/OFF of fixed range ring while cursor is put on the
fixed range ring interval (numerical value).
1.15.2
Using VRM (Variable Range Ring)
There are two types of VRM; VRM1 and VRM2, which are shown by broken lines to distinguish
from fixed range ring. The two types of VRM can be distinguished from each other by the length
of the broken line also. VRM1 has shorter broken lines and VRM2 has longer broken lines.
1. Press the [VRM ON] key to display VRM.
2. Roll the [VRM] knob to put VRM on the inner side of target to which range you want to
measure. Read range displayed at the lower right side on the screen. VRM value remains
even when range is changed.
3. Press the [VRM OFF] key to delete VRM. The way it is deleted varies according to display
condition of VRM.
•
When both VRM1 and VRM2 are displayed and either VRM1 or VRM2 is in operable
condition, either VRM2 or VRM1 whichever is not in operable condition disappears.
•
When either VRM1 or VRM2 is displayed, the VRM of the displayed one disappears.

1.16 Measuring bearing of target
Use the Electronic Bearing Lines (EBL) to take bearing of targets. There are two EBLs, No.1 and
No.2. Each EBL is a straight broken line extending out from the own ship position to distinguish
from heading line. The two EBLs can be distinguished from each other by the different length of
their dashes; dashes of EBL1 are shorter than EBL2.
1.16.1 Measuring bearing using EBL (Electronic cursor)
1. Press the [EBL ON] key to display either of the EBLs. Each press switches the arrow in the
box between EBL1 and EBL2. The EBL with the arrow mark can be operated with the [EBL]
knob.

1.17 Measuring Range and Bearing between Two
Targets
Range and bearing between two targets can be measured by moving EBL origin.
1. Press the [EBL ON] key to display EBL1.
2. [Press the EBL offset] key. The EBL origin moves to the cursor position.
3. Roll the trackball to move the cursor on target A.
4. Roll the [EBL] knob to put EBL1 at the center of target B.
5. Press the [VRM ON] key to display VRM1.
6. Roll the [VRM] knob so that VRM1 touches target B. Range and bearing between the two
targets are displayed at the lower section on the screen. Press the [EBL offset] key to return
the EBL origin to the center of the screen.

Bearing/Range between target C and D
Similarly, range and bearing between target C and target D can be measured using EBL2 and
VRM2.
Note: User can select the method of fixing origin of EBL offset. (See page 2-31.)
1.18 Selecting Transmission Pulse Length
Transmission pulse length is displayed at the upper left side on the screen. Pulse length can be
changed according to situations except for far range. To emphasize far range detection, extend
the pulse length and to emphasize resolution, shorten the pulse length. Shortening pulse length
can also reject precipitation clutter.
1. Roll the trackball to put the cursor on the pulse length box at the upper left side on the screen.
Pulse length box
2. Left-click to shorten the pulse length and right-click to lengthen the pulse length.
Each click switches between available pulse lengths in the current range scale.
18
1.19 Off-Centering the Display
Own ship position, or sweep origin, can be displaced to expand the view field without switching
to a larger range scale. The sweep origin can be off-centered to the cursor position, but not more
than 75% of the range in use. In the true dynamic mode, the sweep origin can be off-centered to
the cursor position within 50% of the range in use.
Note: This function can be used for ranges other than 96NM and 120NM ranges.
1. Roll the trackball to move the cursor to a position where you wish to center the image.
2. Press the [OFF CENTER] key. Own ship position moves to the cursor position.
3. Press the [OFF CENTER] key again to return the own ship position to the previous position.
1.20 Rejecting Interference
Mutual radar interference may occur in the vicinity of another
ship borne radar operating in the same frequency band. (X
band: 9GHz) It is seen on the screen as a number of bright
spikes either in irregular pattern or in the form of dotted lines
extending from the center of the edge of the picture. This
type of interference can be rejected by the interference
rejecting function.
Interference by other ship s radar
1. Roll the trackball to put the cursor on the box next to the [Interference] at the upper left side
on the screen.
2. Left-click to select the strength of interference rejection. Each click switches between OFF
→1→2→3. The larger the value, the stronger the interference rejection, however, it may
weaken ship’s echo.
Note: Set the level of interference rejection function at OFF when there is no interference
from other ships to avoid missing small targets near own ship.
1.21 Echo Stretch
The echo stretch feature enlarges targets in the range and bearing directions to make them
easier to see. There are three levels of echo stretch, 1, 2 and 3. We recommend the level 3 for
normal use.
Note: The echo stretch magnifies not only small target pips but also clutter from sea surface,
precipitation and radar interference. For this reason, make sure these types of interference have
been sufficiently reduced before activating the echo stretch function.
1. Roll the trackball to put the cursor on the box next to [Stretch] at the upper left side on the
screen.
19
2. Left-click to select the desired setting. Each click switches between OFF→1→2→3. Set the
echo stretch level while observing the screen.
•
OFF: no stretch
•
•
•
1: Smooth eco
2: Stretches 1.2 ~ 1.5 times in the bearing direction
3: Stretches in range and bearing directions.
1.22 Signal Processing Function
Rejecting sea clutter may also reject necessary targets. In such a case, the signal processing
function can suppress sea clutter while maintaining targets.
Note 1: Heading bearing signal and own ship positioning data are necessary for the signal
processing function
Note 2: Do not use the signal processing function in rough conditions of pitching and rolling of
own ship to avoid loss of target.
Note 3: Targets moving at high speed become difficult to detect compared of static targets when
using the signal processing function. Prior to using the signal processing function, use the sea
clutter rejection function just so some weak sea clutter appears on the screen.
1. Roll the trackball to put the cursor next to [Processing] at the upper left side on the screen.
2. Left-click to select the desired setting. Each click switches the setting between
OFF→1→2→3→4→5. Set a value while observing the echoes.
•
Off: Set the signal processing function OFF.
•
1,2: Effective for target detection in sea clutter. The signal processing 2 is more effective
compared with the signal processing 1 for target detection in strong sea clutter. However,
detecting targets moving at high speed on the screen is more difficult for the signal
processing 2 compared with the signal processing 1. Use either the signal processing 1
or 2 in accordance with user’s purpose. When detecting targets in sea clutter and targets
moving at high speed simultaneously, it becomes effective to use the signal
processing function together with the wiper processing (See page 2-20.)
3. Detect weak targets, such as floats, in stormy weather.
4. Detect weak targets, such as floats, in stormy weather. To use this setting, set the
equipment as follows:
•
•
Set the interference rejector to 3. This raises the sensitivity against weak targets.
•
•
Manually set the A/C SEA to 50.
Manually set the gain to 80.
Manually set the A/C RAIN to 40. This is effective for reducing unwanted clutter and
suppressing false echoes.
5. Effective for detecting high speed targets and unstable echoes.

1.23 Echo Trail Function
Echo trail function is useful to observe other ships’ movement, which displays a track in lower
brilliance than the actual image
1.23.1 Starting Echo Trail
Set trail time to start the echo trail. Trail time can be selected from 15 seconds, 30 seconds, 45
seconds 1-20 minutes (1 min. interval), 30 minutes, 40 minutes, 50 minutes, 60 minutes, 20
hours, 24 hours, 48 hours and continuous. Trail is displayed for the set trail time.
1. Press the [Echo Trail] key several times to select the desired trail time.
The trail time currently selected is displayed in the trail box at the lower right side on the
screen. The longer the trail time, the longer the trail becomes.
Elapsed time

Elapsed time from the start of the trail to the set trail time is shown on the trail box. For
example, if the trail time setting is 6 min., the elapsed time is displayed until 6 minutes is
elapsed but no elapsed time is displayed beyond 6 minutes.
2. Put the cursor on [On] in the trail box and left-click to temporarily erase the trail from the
screen. The display in the box changes to [Off]. The trail display disappears from the screen
but it continues trail inside the machine.
Note 1: Color, gradation and level can be changed in the [Trail] menu. (See chapter 2.10.5)
Note 2: Long press the [Echo trail] key to delete all the trails in the machine to start over the trail.
You can also put the cursor on the [Trail] (or [On], Trail time) in the trail box and long press the
left button.
1.23.2 Selecting Trail Mode
There are relative trail and true trail modes for echo trails.
Relative trail: Relative trails show other ships’ movement with reference to own ship. Relative
trail is useful to see relative movements such as avoiding a collision because own ship’s
movements and other ships’ movements are combined. On the other hand, it also shows trails of
fixed targets to make it difficult to see depending on locations.
True trail: True trails show other ships’ true movements in accordance with their over-the-speed
over grounds and courses regardless with own ship’s movement. Therefore, trails of stationary
targets are not drawn. Heading bearing signal and GPS navigation equipment need to be
connected.

Note: When setting of trail mode is changed, TRUE, TRUEs or REL also change in the trail
interval box in the information display area.
1.24 Watch Alarm
The watch alarm sounds the audio alarm and displays the alarm message when targets (other
ships, island, reef, etc.) enter the set zone (Enter mode) or exit the set zone (Exit mode). (The
[Watch Alarm] is ON in the ALARM menu.) User can set two alarm zones. The default setting of
[Watch Alarm] is the Enter mode. Chapter 2.11.2 explains switching between the modes.
Warning
Watch alarm function helps prevention
of collisions and use of the function
does not exempt users from operational
safety obiigagtions stipulated in the
prevention of sea cliiision notices.
When adjustments are inadequate for
gain, sea clutter rejection and
percipitation clutter rejection, alarm
function may be lost against actual
target and talse alarm may sound due to
sea clutter and rain etc.

3. TARGET TRACKING (TT)
3.1 Usage Precautions
Purpose of this function is to aid route monitoring for navigational safety. It is not a substitute of
basic navigational principles and common sense of navigators. Excessive reliance on the
monitoring of the equipment or erroneous handling of the equipment could adversely cause a
dangerous result. Please note the following very carefully.
Depending on radar setting, it may fail to acquire necessary targets or track unnecessary echoes
such as sea clutter. In some cases, radar settings may be unsuitable to the functions. Adjust
each radar function properly to suite each situation.
Normal acquisition and tracking may become difficult in situations such as strong and wide sea
clutter or precipitation, targets in low clouds and many noise interferences. Make adjustments
accordingly to reject excessive sea clutter and precipitation clutter. Please note also that
necessary targets could disappear when gain setting is too low or sea clutter rejection setting is
too high.
Tracking errors
The plotting accuracy and response of this TT meets IMO standards. Tracking accuracy is
affected by the following. Own ship’s slow course change does not affect the tracking accuracy,
however, fast course change may affect all the tracking targets and may take one to two minutes
to restore vectors to full accuracy. (The actual amount depends on gyrocompass specifications.)
The amount of tracking delay is 15~30 seconds to display the course of TT target when other
ships’ relative speed is fast and 30~60 seconds of delay when other ships’ relative speed is slow
(close to zero). Accuracy may drop a little during a course change but will restore in short time.
Display accuracy
The following items may affect display accuracy.
1) Echo intensity
2) Radar transmission pulse length
3) Radar bearing error
4) Gyrocompass error
5) Course change of own ship and other ship (response error)

3.3 Ship Speed Input
The TT requires own ship’s speed and heading data. The speed can be speed over ground,
speed over water, or echo-referenced speed (based on 3 max. stationary objects). Echoreferenced ship speed is explained here.
The use of echo-referenced speed is recommended when:
• The speed log is not operating properly or not connected to the radar.
• The vessel has no device (Doppler sonar, speed log, etc.)
• No position sensor input
If you select echo-referenced speed, the TT calculates own ship’s speed relative to a fixed
reference target. This method is effective when error is large due to ship’s port-starboard
movement. The number of targets may be numbered R1, R2 or R3.
1. Select [Speed over ground] for [Ship speed] in the [Ship speed] menu. (See chapter 2.10.8.)
2. Select [Echo-referenced speed] for [Speed over ground] in the [Ship speed] menu. [Echoreferenced speed] is displayed in the ship speed section in the information display area.
3. Move the cursor to a stationary object such as a small island or a light house within 0.1~24
(or 32) NM range from own ship.
4. Right-click to display the [Cursor] menu.
5. Select [Stationary target] then left-click. A fixed point mark is entered at the cursor position.
Ship speed is displayed after about one minute.

6. Repeat steps 3~5 to mark the maximum of three stationary objects.
Note1: The fixed point mark disappears when echo disappears during acquisition and tracking
stationary target. The flashing indication [Stationary target lost] is displayed in the alarm box in
the information display area.
Note 2: Put the cursor on the fixed point mark then press the [Delete target] key to delete the
fixed point mark.
Note 3: You can display a vector on a stationary object by selecting [On] at [Fixed target vector]
in the [TT target] menu.
67
Notes on input of speed with a fixed target
• Select a stationary target as a reference target to calculate own ship speed as ground tracking
speed. Do not choose a moving target as a reference target. A moving target produces in error
in the vector for TT and AIS, which results in wrong collision avoidance information. Further,
an unstable stationary target produces inaccurate speed data and the target itself may
become lost.
• When all stationary targets are lost, the ship speed values becomes [---] in the information
display area. Reselect other stationary targets.
• When acquisition of all targets is interrupted, acquisition of stationary targets is also
interrupted and calculation of echo-reference speed becomes impossible.
Stop echo-referenced display
Select [GPS] or [Log (over ground)] for [Speed over ground] in the [Ship speed] menu.

3.13 Setting Collision Alarm (CPA/TCPA alarm)
Thresholds of CPA (the Closest Point of Approach of other ship to own ship) and TCPA
(predicted time to CPA) can be preset to avoid a collision with other ship. (Settings are common
with AIS targets. See chapter 4.10.) When both CPA and TCPA of a tracking target become
smaller than the preset CPA and TCPA thresholds, the target becomes a dangerous target (red
flashing) and audio alarm sounds.
This function is useful to avoid the risk of collision with the target. It is very important, however, to
set gain, sea clutter rejection and precipitation clutter rejection correctly.
Note 1: The collision alarm is a support function for detecting the risk of collision. The navigator
is responsible to keep visual lookout for avoiding collisions at all times.
Note 2: Consider size of own ship, tonnage, ship speed and turning capacity when setting the
collision alarm.

3.15 Test Steering (Steering simulation)
Test steering is a simulation to avoid collision. Enter a test course, ship speed and delay time
before starting the test steering to display the simulation result to predict the position relationship
with other ship. This function is useful to avoid the risk of collision by setting CPA and TCPA in
the steering simulation. Repeat entering various test courses, ship speeds and delay time until
no dangers exist. Acquisition and tracking of targets continue during the steering simulation. Use
relative motion and speed over water vector to display more accurate results. It is necessary to
set up characteristics of own ship correctly such as acceleration, turning capacity in order to
perform more accurate simulation.
3.15.1 Types of steering simulation
There are the two types of mode, dynamic mode and static mode in steering simulation.
Dynamic mode
Dynamic mode continuously displays motions of tracking target and own ship. Predicted
positions of own ship and each target are displayed every 30 second in the steering simulation.
Preset own ship speed, course and delay time. Display is updated every one second. Delay time
means the time between the current time to the time when own ship changes its course and
speed.
The illustration shows the own ship that is set to change its course and speed after 2 min. 30 sec.
(OS5 position). OS6 and OS7 indicate positions where course and speed are being changed.
OS8 indicates a position after the change of course and speed took place.

Static mode
Static mode shows the result of the steering simulation indicating the position relationship
between own ship and a tracking target. The steering simulation calculates the elapsed time
(initial testing time) until own ship reaches the set course and speed and shows the own ship at
that position. Each target is displayed at the position when the simulation time elapses.
You can increase or decrease the simulation time to see the results at arbitrary time settings.
Static mode is useful to immediately know the result of the steering simulation.

Dynamic mode
Estimated positions of own ship and each target are updated and displayed every 30
seconds. Simulation time increases every 30 seconds.
Static mode
Positions of your ship and tracked targets are displayed when own ship reaches the set
course and speed. The elapsed time to reach that position is indicated as the initial
simulation time. After that, put the cursor on the simulation time box and roll the wheel to
change the simulation time. Shorten the simulation time to display the result at the earlier
position and lengthen the simulation time to display the result at the later position. Remove
the cursor from the simulation time box to return the positions of own ship and each target to
the positions of the initial simulation time. When the result of the steering simulation is
unsatisfactory, repeat the simulation by changing the simulation ship speed, course and
delay time until you can obtain a satisfactory result.
88
The letter “T” appears at the lower section on the screen during the trial maneuver. If any tracked
target is predicted to be on a collision course with own ship (that is, the target ship comes within
preset CPA/TCPA limits), the target plotting symbol flashes in red. If this happens, change own
ship’s trial speed, course or delay time to obtain a safe maneuver.

Magnetron
Magnetron gradually lowers its output as transmission continues. When sensitivity of targets in
far distance lowers, request for a replacement of magnetron to a technician. When magnetron is
used for the purpose of detecting small targets in far range, the recommended replacement
schedule will be shorter than the numbers in the above schedule table.
