◆◆◆ PRECAUTIONS BEFORE OPERATION ◆◆◆
■ Cautions for high voltage
High voltages from hundreds volts to tens of thousands volts are to be applied to
the electronic equipment such radio and radar devices. You do not face any
danger during normal operation, but sufficient cares are required for maintenance,
inspection and adjustment of their internal components. (Maintenance, check-up
and adjustment of the inside of the equipment are prohibited except by
maintenance specialists.)
High voltages of tens of thousands volts are so dangerous as to bring an
instantaneous death from electric shock, but even voltages of hundred volts may
sometimes lead to a death from electric shock. To prevent such an accident, make
it a rule to turn off the power switch, discharge capacitors with a wire surely
earthed on an end make sure that internal parts are no longer charged before you
touch any parts inside these devices. At the time, wearing dry cotton gloves
ensures you further to prevent such danger. It is also a necessary caution to put
one of your hands in the pocket and not to use your both hands at the same time.
It is also important to select a stable foothold always to prevent additional injuries
once you were shocked by electricity. If you were injured from electric shock,
disinfect the burn sufficiently and get it taken care of promptly.
■ What to do in case of electric shock
When finding a victim of electric shock, turn off the power source and earth the
circuit immediately.
If it is impossible to turn off the circuit, move the victim away promptly using
insulators such as dry wood plate and cloth without touching the victim directly.
In case of electric shock, breathing may stop suddenly if current flows to the
respiration center in the brain. If the shock is not so strong, artificial respiration
may recover breathing. When shocked by electricity, the victim will come to look
very bad with weak pulse or without beating, resulting in unconsciousness and
rigidity. In this case, it is necessary to perform an emergency measure
immediately.
◆◆◆ FIRST-AID TREATMENTS ◆◆◆
☆ First-aid treatments
As far as the victim of electric shock is not in dangerous condition, do not move
him and practice artificial respiration on him immediately. Once started, it should
be continued rhythmically.
(1)
Do not touch the victim confusedly as a result of the accident, but the
rescuer may also get an electric shock.
(2)
Turn off the power source calmly and move the victim away quietly from
the electric line.
(3)
Call a physician or ambulance immediately or ask someone to call a doctor.
(4)
Lay the victim on this back and loosen his necktie, clothes, belt, etc.
(5)
a.
Examine the victim's pulse.
b.
Examine his heartbeat bringing your ear close to his heart.
c.
Examine his breathing bringing the back of your hand or your face
close to his face.
d.
Check the size of the pupils of his eyes.
(6)
Open the victim's mouth and take out artificial teeth, cigarette or chewing
gum if any. Keep his mouth open, stretch his tongue and insert a towel or
the like in his mouth to prevent the tongue from suffocating. (If it is hard to
open his mouth due to set teeth, open it with a screwdriver and insert a towel
in this mouth.)
(7)
Then, wipe his mouth so that foaming mucus does not accumulate inside.
ii
☆ When pulse is beating but breathing has stopped
(Mouth-to-mouth respiration) Fig 1.
(1)
Tilt the victim's head back as far as this face looks back. (A pillow may be
inserted his neck.)
(2)
Push his jaw upward to open his throat wide (to spread his airway).
(3)
Pinch the victim's nostrils and take a deep breath, block his mouth
completely with yours and blow into his mouth strongly. Take a deep breath
again and blow into his mouth. Continue this 10 to 15 times a minutes
(blocking his nostrils).
(4)
Carefully watch that he has recovered his natural breathing and atop
practicing artificial respiration.
(5)
If it is difficult to open the victim's mouth, insert a rubber or vinyl tube into
one of his nostrils and blow into it blocking the other nostril and his mouth
completely.
(6)
When the victim recovers consciousness, he may try to stand up suddenly,
but let him lie calmly and serve him with a cup of hot coffee or tea and keep
him warm and quiet. (Never give him alcoholic drinks.)
Method of mouth-to-mouth respiration by raising hea
(1)Raise the victim's head. Support
his forehead with one of your hand
and his neck with the other hand. 1
When you tilt his head backward, the
victim, in most cases, opens his
mouth to the air. This makes mouthto mouth respiration easy.
(2)Cover his mouth as widely as
possible with yours and press your
cheek against his nose 2
or, pinch his nostrils with your fingers
to prevent air from leaking. 3
(3)Blow into his lungs.
Continue
blowing into his mouth until his breast
swells. Blow into his mouth as quickly
as possible for the first 10 times.
Fig 1. Mouth-to mouth respiration
iii
☆ When both pulse and breathing have stopped
Perform the (Cardiac massage) Fig 2. and (Mouth-to-mouth respiration) Fig 1.
When no pulse has come not to be felt, his pupils are open and no heartbeat is
heard, cardiac arrest is supposed to have occurred and artificial respiration must
be performed.
(1)
Place your both hands, one hand on the other, on the lower one third area of
his breastbone and compress his breast with your elbows applying your
weight on his breast so that it is dented about 2cm (Repeat compressing his
breast 50 times or so a minutes). (Cardiac massage)
(2)
In case of one rescuer,
Repeat cardiac massages about 15 times and blow into his mouth 2 times
quickly, and repeat this combination.
In case of two rescuers,
One person repeats cardiac massages 15 times while the other person blow
into his mouth twice, and they shall repeat this combination. (Perform the
cardiac massage and mouth-to-mouth respiration)
(3)
Examine his pupils and his pulse sometimes. When the both have returned
to normal, stop the artificial respiration, serve him with a cup of hot coffee
or tea and keep him warm and calm while watching him carefully. Commit
the victim to a medical specialist depending on his condition. (Never give
him alcoholic drinks.) To let him recover from the mental shock, it is
necessary for persons concerned to understand his situations and the
necessary treatment.

● PRECAUTIONS ●
Never conduct inspection or repair work of equipment
components.
Inspection or repair work by uncertified personnel may
result in fire hazard or electrocution.
For inspection and repair work of equipment
components, consult with our branch office, branch
shop, sales office, or our distributor in your district.
When conducting maintenance, make sure to turn the
main power off.Failure to comply may result in
electrocution.
Turn off the main power before cleaning the equipment.
Especially when a rectifier is used, make sure to turn it
off since voltage is still outputted from the rectifier even
after the indicator and the radar are turned off. Failure to
comply may result in equipment failure, or death or
serious injury due to electric shock.
When conducting maintenance work on the scanner,
make sure to turn its main power off.Failure to comply
may result in electrocution or injuries.
vii
!
Make sure to turn off the scanner safety switch. Failure to
comply may result in injuries caused by physical contact
with the rotating scanner.
Never directly touch the internal components of the
scanner or indicator. Direct contact with these highvoltage components may cause electrocution. For
maintenance, inspection, or adjustment of equipment
components, consult with our branch office, branch
shop, sales office, or our distributor in your district.
To contact our sales department, branch offices, branch
shops, and sales offices:
Please refer to the "Office List" at the end of the
document.
Do not get close to the radiant section of the scanner. It
is a rotating part, and it may cause injuries if it suddenly
starts rotating and consequently hits the body. It is
recommended that the radiant section be installed at a
high place such as on the roof of the wheelhouse, on the
flying bridge, on the trestle, or on the radar mast so that
no one can get close to it. When any work must be done
on the scanner, make sure to turn the safety switch off.
viii
Microwave radiation level:
Keep away from a scanner when it is transmitting.
The high level of microwave is radiated from the front
face of the scanner specified below. The microwave
exposure at close range could result in injuries
(especially of the eyes).
Microwave radiation level
System 10 W/m2
NKE-1532 10cm
Make sure to install the scanner at a place higher than
human height.
Direct exposure to electromagnetic waves at close range
will have adverse effects on the human body. When it is
necessary to get close to the scanner for maintenance or
inspection purposes, make sure to turn the indicator
power switch to "OFF" or "STBY."
Direct exposure to electromagnetic waves at close range
will have adverse effects on the human body.
Direct exposure to electromagnetic waves at close range
will have adverse effects on the human body.
When conducting maintenance work, make sure to turn
off the power so that the power supply to the equipment
is completely cut off.
Some equipment components can carry electrical current
even after the power switch is turned off, and conducting
maintenance work without unplugging the power
connector may result in electrocution, equipment failure,
or accidents.
ix
When cleaning the display screen, do not wipe it too
strongly with a dry cloth. Also, do not use gasoline or
thinner to clean the screen. Failure to comply will result
in damage to the screen surface.
Do not change MBS Level/Area unless absolutely
necessary.
Incorrect adjustment will result in deletion of nearby
target images and thus collisions may occur resulting in
death or serious injuries.
When disposing of used lithium batteries, be sure to
insulate the batteries by attaching a piece of adhesive
tape on the + and - terminals. Failure to comply may
cause heat generation, explosion, or fire when the
batteries get shorted out.
Use the radar only as a navigation aid. The final
navigation decision must always be made by the
operator him/herself. Making the final navigation decision
based only on the radar display may cause accidents
such as collisions or running aground.
!
Use Target Tracking (TT) function only as a navigation
aid. The final navigation decision must always be made
by the operator him/herself. Making the final navigation
decision based only on tracking target information may
cause accidents.
Tracking target information such as vector, target
numerical data, and alarms may contain some errors.
Also, targets that are not detected by the radar cannot be
acquired or tracked.
Making the final navigation decision based only on the
radar display may cause accidents such as collisions or
running aground.
A malfunction may occur if the power in the ship is
instantaneously interrupted during operation of the radar.
In this case, the power should be turned on again.
When using the [AUTO SEA] function, never set the
suppression level too high canceling out all image noises
from the sea surface at close range.
Detection of not only echoes from waves but also targets
such as other ships or dangerous objects will become
inhibited.
When using the [AUTO SEA] function, make sure to
choose the most appropriate image noise suppression
level.
When using the [AUTO RAIN] function, never set the
suppression level too high canceling out all image noises
from the rain or snow at close range.
Detection of not only echoes from the rain or snow but
also targets such as other ships or dangerous objects
will become inhibited.
When using the [AUTO RAIN] function, make sure to
choose the most appropriate image noise suppression
level.
xi
!
When setting a guard zone, make sure to properly adjust
gain, sea-surface reflection suppression level, and rain/
snow reflection suppression level so that the optimal
target images are always on the radar screen. The guard
zone alarm will not be activated for targets undetected by
the radar, and it may result in accidents such as
collisions.
The simulation function is used exclusively for deciding
whether or not target tracking is properly operating.
Therefore, never use this function unless you wish to
check target tracking operations.
Note especially that, if this function is used during actual
navigation, simulated targets are displayed and may
become confused with other actual targets. Therefore,
never use this function during actual navigation.
Optimal values have been set for VD LEVEL and
CONSTANT; therefore, never change their values unless
absolutely necessary. Failure to comply may result in
accidents that would lower target tracking performance.
Make sure to shut off the main power before replacing
parts. Failure to comply may result in electrocution or
equipment failure.
xii
!
Make sure that two or more staff member work together
when replacing the LCD. If only one person attempts to
replace the LCD, he/she may drop it and become injured.
Do not directly touch the inverter circuit of the LCD
display with a bare hand since high voltage temporarily
remains in the circuit even after the main power is shut
off.
Failure to comply may result in electrocution.
Any adjustments must be made by specialized service
personnel.
Incorrect settings may result in unstable operation.
Do not make any adjustments during navigation. Failure
to comply may result in adverse effects on the radar
function which may lead to accidents or equipment
failure.
Any adjustments must be made by specialized service
personnel.
Failure to comply may result in accidents or equipment
failure.
Do not make any adjustments during navigation. Failure
to comply may result in adverse effects on the radar
function which may lead to accidents or equipment
failure.
Do not change the quantization level settings unless
absolutely necessary. If set at an inappropriate value, the
target acquisition or target tracking function deteriorates,
and this may lead to accidents.

1.2
FEATURES
Realization of Large, Easy-to-see Screen with High Resolution
The 23.1-inch color LCD1 with high resolution can display radar images of 320
mm or more in diameter. Even short-range targets can also be displayed as highresolution images.
Target Detection by Latest Signal Processing Technology
The system employs the latest digital signal processing technology to eliminate
undesired clutter from the radar video signals that are obtained from the receiver
with a wide dynamic range, thus improving the target detection.
Target Tracking (TT) Function based on Advanced Technology
The target acquisition and tracking performance is enhanced by the use of the
fastest DSP and tracking algorithm. So stable operation in target tracking under
clutter is ensured.
• Acquisition and tracking of 100 targets.
• Hazardous conditions are represented by shapes and colors of symbols as well
as sounds.
• Trial maneuvering functions provided.
• Tracks of up to 20 target ships can be stored with a maximum of 1,500 points
for each of them, and displayed distinguished by using seven different colors.
Overlay of Radar Images, Coastlines, and Own Ship's Track
As well as operator-created NAV lines and own ship's tracks/ARPA tracks, which
is stored on the memory card can be superimpose-displayed with radar images and
radar trails in all display modes including the head-up mode.
Easy Operation with GUI
All the radar functions can be easily controlled by simply using the trackball and
two switches to operate the buttons shown on the radar display.
1.The displayed resolution corresponds to SXGA(1280x1024).
1－2
JMA-9172-SA Instruction Manual > 1.GENERAL AND EQUIPMENT COMPOSITION > 1.2 FEATURES
Improved Day/Night Mode
Five types of background colors are available in Day/Dusk/Night mode (total 5
background colors). Each background color can be reproduced to be suited for the
user's operating environment by simple key operation. The radar echoes and a
variety of graphics can also be represented in different colors, ensuring easy-tosee displays.
Compact Design and Low Power Consumption
Since an LCD has been implemented as the display device, the weight of the
display is greatly reduced and the power consumption is lowered in comparison
with the conventional radar equipment.
Self-diagnostic Program Incorporated
The Self-diagnostic program always monitors all the functions of the system. If
any function deteriorates, an alarm message will appear on the radar display and
an alarm sounds at the same time. Even when the system is operating, the
functionality test can be carried out. (except on some functions)
Performance Monitor
The radar performance (transmitted output power and receiving sensitivity) can
appear on the radar display.

Adjust Gain [GAIN]
If the gain is too high, unnecessary signals including
receiver noise and false images increase resulting in
reduction of visibility of targets.
On the contrary, if the gain is too low, targets including
ships and dangerous objects may not be clearly
indicated.
Be sure to always adjust for the best gain.
See also the Section 3.2.8 "To get the appropriate image that targets can be easily
observed".
Procedures
1)
Adjust noise on the radar display by turning the [GAIN] dial until
targets can be easily observed.
Turning [GAIN] dial clockwise increases gain.
Turning [GAIN] dial counterclockwise decreases gain.
Turning the [GAIN] dial clockwise will increase the receiving gain, and the
range to observe radar video is widened. However, if the gain is too high,
unnecessary signals including receiver noise and false images increase
resulting in reduction of targets' visibility.
To observe densely crowded targets or short-range targets, turning the
[GAIN] dial counterclockwise will decrease the receiving gain, which
enables targets to be easily observed. However, caution must be taken so
as not to overlook a small and important target.
It is recommended to restore the setting to
the factory default, if you lost the appropriate
settings.The factory default level is shown on

of a target can easily be read out.
Relative Bearing Mode [Head Up]
The video is displayed so that the ship’s heading line points to the zenith of the PPI (0° on
range rings). Since targets are displayed in their directions relative to the ship’s heading line,
the operator can view the video in the same field of view as in operating the ship at sea. This
mode is suitable for watching over other ships.
Course-up Bearing Mode [Course Up]
By setting the course-up mode, own ship's course is fixed so that it is located on the zenith of
the radar display (0° on range rings). In the same way as in the North-up mode, fixed targets
do not flicker, and are stabilized even if the ship is yawing. The bearing of the heading line

: Use this mode to detect small targets such as fishnets of round haul
netters hidden by sea clutter returns. (Importance is attached to sea
clutter suppression, and gain to moving targets lowers.)
: Use this mode when many rain / snow clutter returns or sea clutter
returns are detected in stormy weather. (Importance is attached to rain /
snow clutter and sea clutter suppression, and gain slightly lowers.)
: Use this mode when only a few rain / snow clutter returns or sea clutter
returns are detected.

• Detects unwanted waves such as rain/snow clutter and sea clutter and
automatically suppresses them.
• When the sea state or weather changes, this function automatically performs
suppression processing in accordance with the situation.
• Suppression processing is not full automatic, and requires the operator to adjust
the afterimages of unwanted waves.
• To adjust the afterimage of sea clutter, use the [SEA] dial.
• To adjust the afterimage of rain/snow clutter, use the [RAIN] dial.
• In areas where the density of unwanted waves is low, unwanted waves may
remain being judged as targets. Thus, use the automatic clutter suppression
mode together with the video process mode.
• Characteristics of the automatic clutter suppression function:
Off
AUTO Sea
: Disables the automatic clutter suppression function. Select off
when rain / snow clutter and sea clutter are not strong or when the
ship is in a bay.
: Automatically detects the strength of sea clutter, and performs the
most suitable sea clutter suppression processing.
Even when the strength of sea clutter varies depending on the wind
direction, AUTO Sea performs the most suitable suppression
processing. Land like islands can be displayed naturally.
AUTO Sea/Rain
Since rain clouds outside sea clutter areas are recognized as land,
there is no effect of suppressing rain / snow clutter.
: Along with AUTO Sea, AUTO Rain automatically detects the
strength of rain / snow clutter, and performs the most suitable rain /
snow clutter suppression processing.
When rain clouds are scattered about, AUTO Rain performs rain /
snow clutter suppression processing for only the rain-cloud areas.
Since land is recognized as rain clouds, land videos become
obscure.

• Corrects gain while the function mode is called.
• Since the displayed noise level varies depending on the combination of the
video process mode and the interference rejection level, gain needs fine
adjustment for always obtaining the highest level.
• The gain correction function saves the correction value set by the gain adjust in
each function mode, so it can obtain the highest gain without the gain adjust
being operated when the function mode is changed.
• To set high gain, set a value on the “+”side.
• To set low gain, set a value on the “-”side.
• When the radar interference rejection level is increased, the noise level is
lowered. Thus, set a gain correction value to the “+”side.
• When the video process mode 3Scan CORREL , 4Scan CORREL , or
5Scan CORREL
is used, the noise level is lowered. Thus, set a gain correction
value to the “+”side.

5.1 PREPARATION
PREPARATION
Attention
• There are the following limitations on use of the target acquisition and target
tracking functions.
[I] Resolution between adjacent targets and swapping during automatic target
tracking
Depending on the particular distance and echo size, resolution between adjacent
targets during automatic target tracking usually ranges somewhere between 0.03 to
0.05 NM. If multiple targets approach each other, resolution will become about 0.05 NM
and this may cause the system to regard them as one target and thus to swap them or
lose part of them. Such swapping or less of targets may also occur if the picture of the
target being tracked is affected by rain/snow clutter returns or sea clutter returns or
moves very close to land.
[II] Intensity of echoes and the target tracking function
The intensity of echoes and the tracking function have a correlationship, and thus the
target will be lost if no echoes are detected during six scans in succession. If a lost
target exists, therefore, radar gain must be increased to support detection of the target.
If, however, radar gain is increased too significantly, sea clutter returns or other noise
may be erroneously detected and tracked as a target, and resultingly, a false alarm
may be issued.
[III]Adverse effects of error sources on automatic tracking
To execute accurate tracking, it becomes necessary first to appropriately
adjust the [GAIN], [SEA] and [RAIN] dials of the radar so that the target
to be acquired and tracked id clearly displayed on the radar display.
Inappropriate settings of these adjustments reduce the reliability /
accuracy of automatic tracking.
This section explains the features of the target tracking and AIS functions, and the
initial setting for using each function.
Target Tracking Function
The target tracking function calculates the course and speed of a target by
automatically tracking the target's move.
The target tracking function enables the automatic acquisition of targets by using
the automatic acquisition zone function.
The target tracking function also enables the simulation of the ship maneuvering
method to avoid collisions by using the trial maneuver function.

The AIS function shows the target’s information on the radar display, using other
ship's information sent out from the AIS unit.

Collision Avoidance
5.1.1.1
Problems of Collision Avoidance in Navigation
Marine collision avoidance is one of the problems that have been recognized from
of old. Now, it will be described briefly who the collision avoidance is positioned
among the navigational aid problems.
The navigation pattern of all mobile craft constitutes a system with some closed
loops regardless of the media through which the mobile craft travels, whether air,
water, the boundary between air and water, or space. This pattern consists of two
closed loops in principle, one of which is a collision with another mobile craft and
the other is a loop of finding a right and safe way to reach a predeterminate
destination. Fig. 5-1 shows the conceptual diagram of navigation pattern by MR.
E.W. Anderson. The closed loop of collision avoidance is shown on the left side
and the closed loop of finding a right course on the right side.

5.OPERATION OF TARGET TRACKING AND AIS
5.1 PREPARATION
Marine Accidents and Collisions
Among marine accidents, collision accidents have been highlighted as the
tonnages and speeds of ships become higher along with the increase in traffic at
sea. If a tanker carrying dangerous articles such as crude oil collides with any
other vessel, then not only the vessels involved with the accident but other vessels
in the vicinity, port facilities, inhabitants in the coastal area as well as marine
resources may also suffer immeasurable damages and troubles. Collision
accidents have a high percentage of the marine accidents that have occurred in
recent years. To cope with these problems, any effective measures are needed and
some equipment to achieve collision avoidance requirements have been developed
at rapid strides.
5.1.1.3
Basic Concept of Collision Avoidance
There are two aspects in collision avoidance: collision prediction and avoidance.
Collision prediction is to predict that two or more vessels will happen to occupy
the same point at the same time, while collision avoidance is to maneuver vessels
not to occupy the same point at the same time.
In practical operation of vessels, a spot of collision has to be deemed to be a single
point but a closed zone. This closed zone is conceptually defined as a CPA
(Closest Point of Approach). In collision prediction, the time to be taken until a
ship reaches the CPA is defined as a TCPA (Time to CPA).
Fig. 5-2 shows a diagram caked "Collision Triangle".

5.OPERATION OF TARGET TRACKING AND AIS
5.1 PREPARATION
Relative Vector and True Vector
From two points of view, collision prediction and avoidance, it is necessary to
obtain the relative vector of other ship for prediction and the true vector of other
ship for collision avoidance in order to grasp other ship’s aspect. The relationship
between the relative vector and true vector is shown in Fig. 5-3.
Both rough CPA and TCPA can be obtained easily from the relative speed vector
of other ship. This method has an advantage that the risks of collision with all
other ships within the radar range can be seen at a glance. On the other hand, the
course and speed of other ship can easily be obtained from its true speed vector,
enabling other ship’s aspect to be seen at a glance. Thus, the aspects of other ships
(transverse, outsail, parallel run, reverse run, etc. ) as described in the act of
prevention of collision at sea can be readily grasped. If there is a risk of collision
with other ship, the operator can determine which rule to be applied and how to
operate own ship.

5.1.1.5
Radar and Collision Avoidance
Radar is still playing an important roll for collision prevention and positioning.
A plotter is used to further enhance the radar functionality. The plotter is capable
of plotting other positions of other ships in 3 to 6 minute intervals to monitor their
movement. The plots of other ships represent their tracks relative to own ship, and
it is shown whether there is a risk of collision, namely CPA and TCPA can be
obtained. This method using a plotter is fairly effective, but the number of target
ship, which is manually plotted, is limited and it takes several minutes to measure
those.

[2] Relative Vector Mode
The relative vector does not represent the true motion of the target, but its relative
relation with own ship. This means that a target with its relative vector directed to
own ship (passing through the CPA Limit ring) will be a dangerous target. In the
Relative Vector mode, it can be seen at a glance where the CPA Limit of the
dangerous target is.
Therefore, the True / Relative mode shall optionally be used for the purpose of
observation: the True vector mode for grasping the true aspect of a target, and the

Attention
• The reference target function is to be used if the own ship's
speed cannot be displayed normally due to trouble such as a
speed sensor malfunction. Do not use the reference target
function except in emergencies.
• If the speed or course of the own ship is changed or a new
reference target is set, the displayed speed may take 3 minutes or
more to reach the specified speed after the speed / course
change or the setting.
• Even after 3 minutes or more has passed, the speed may differ
from the specified speed depending on the tracking condition.
• If a large radar echo such as a land target is set as a reference
target, the vectors of the speed and other tracking targets will not
be displayed correctly and may cause an accident.
• If a sailing ship is set as a reference target, the vectors of the
speed and other tracking targets will not be displayed correctly
and may cause an accident.
• If the REF. is selected for the speed sensor, the AIS function
cannot be turned on.
• If the reference target is lost or the target tracking function is
stopped, the speed sensor is placed in manual mode MAN .
