◆◆◆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.
☆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 head
(1) Raise the victim’s head. Support his
forehead with one of your hand and his
neck with the other hand. ®j
When you tilt his head backward, the
victim, in most cases, opens his mouth to
the air. This makes mouth-to mouth
respiration easy.
(2) Cover his mouth as widely as possible with
yours and press your cheek against his nose
®k
or, pinch his nostrils with your fingers to
prevent air from leaking. ®l
(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
☆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.

DANGER
- iv -
DANGER
Make sure to turn off the antenna operation switch.
Failure to comply may result in injuries caused by
physical contact with the rotating antenna.
WARNING
Never directly touch the internal components of the
antenna, receiver/transceiver, or indicator. Direct
contact with these high-voltage components may cause
electrocution. For maintenance, inspection, or
adjustment of equipment components, consult with our
branch office, branch shop, sales office, or our distributo
r
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 antenna. 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 antenna, make sure to turn the antenna switch off.
- v -
WARNING
About radiation from the antenna:
Never stare at the antenna from a distance closer than
that specified below for each type of antenna when it is
emitting radiation. Being within the specified distance
from the center of the front face of the antenna may
cause radiation exposure which could result in injuries
(especially of the eyes).
NKE-2102/2252 (radiodensity: 10 W/m2): 0.6 m
NKE-1075 (radiodensity: 10 W/m2): 1.1 m
NKE-1075 (radiodensity: 100 W/m2): 25 cm
Make sure to install the antenna at a place higher than
human height.
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 it is
necessary to get close to the antenna 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.
When conducting maintenance work, make sure to turn
off the power and unplug the power connector J1 of the
processor 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.
- vi -
CAUTION
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.
WARNING
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.
When disposing of used lithium batteries, be sure to
insulate the batteries by attaching a piece of adhesive
tape on the Å and ¡ terminals. Failure to comply may
cause heat generation, explosion, or fire when the
batteries get shorted out.
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.
- vii -
CAUTION
Use ATA 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 ATA information may cause accidents.
ARPA 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.
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.
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.
- viii -
CAUTION
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 ATA/ARPA is properly operating.
Therefore, never use this function unless you wish to
check ATA/ARPA 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 ARPA performance.
Make sure to shut off the main power before replacing
parts. Failure to comply may result in electrocution or
equipment failure.
When replacing magnetrons, make sure to shut off the
main power and let the equipment stand for more than 5
minutes to discharge the high-voltage circuit. Failure to
comply may result in electrocution.
- ix -
CAUTION
Make sure to take off your watch when your hand must
get close to the magnetron.
Failure to comply may result in damage to the watch
since the magnetron is a strong magnet.
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.
- x -
CAUTION
Do not change the quantization level settings unless
absolutely necessary. If set at an inappropriate value,
the acquisition or tracking function of ARPA deteriorates,
and this may lead to accidents.

1.2 FEATURES
Realization of Large, Easy-to-see Screen with High Resolution
The 18.1-inch color LCD with high resolution of 1280 ´ 1024 pixels can display radar images of 250 mm or
more in diameter. Even short-range targets can also be displayed as high-resolution 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.
Advanced Technology Based ARPA/ATA Functions (Option)
The ARPA 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 for ARPA, 30 targets for ATA.
· Hazardous conditions are represented by shapes and colors of symbols as well as sounds.
· Trial maneuvering functions provided. (ARPA)
· Trails 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, the data of coastlines, objects such as buoys, and own ship's
tracks/ARPA trails, 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.
Use of the optional plotter function enables the creation/display of marks and lines and the settings of
waypoints/courses.
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 - 3
Improved Day/Night Mode
Two types of background colors are available in each Day/Night mode (total 4 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-to-see 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 (Option)
The radar performance (transmitted output power and receiving sensitivity) can appear on the radar display.
* The PM unit (NJU-63/64) is needed separately.
Easy Interswitch Operation (Option)
If an interswitch unit (option) is connected, up to four JMA-5300 radars can be switched over by performing
simple operation.
* An interswitch (NQA-3141-4) is needed separately.
Various Functions
· TRAILS (Other ship’s) track display
· TM (True Motion display)
· Head-up/North-up/Course-up display
· Own ship’s track display

l Wait for about 2 seconds before turning on the
power again.
l Immediately after the radar is installed, at start of the
system after it has not been used for a long time, or
after the magnetron is replaced, preheat the
equipment in the standby state for 20 to 30 minutes
before setting it into the transmit state.
l If the preheating time is short, the magnetron
causes sparks, resulting in its unstable oscillation.
Start transmission on a short-pulse range and
change the range to the longer pulse ranges in turn.
If the transmission is unstable in the meantime,
immediately place the system back into the standby
state and maintain it in the standby state for 5 to 10
minutes before restarting the operation.
Repeat these steps until the operation is stabilized.

3.4.4 Tune
This system tunes the transmitting frequency and receiving frequency under automatic control, so it does not
need any tuning by hand
3.4.5 Control Sensitivity [GAIN/PL]
Procedures 1 Control noise on the radar display by turning the [GAIN/PL] control until
targets can be easily observed.
Turning [GAIN/PL] control clockwise increases sensitivity.
Turning [GAIN/PL] control counterclockwise decreases sensitivity.
Turning the [GAIN/PL] control clockwise increases receiving sensitivity and extends the
radar observation range. If the sensitivity is too high, the receiver noise increases reducing
the contrast between the targets and the background video. As a result, the targets become
obscure on the radar display.
To observe densely crowded targets or short-range targets, turn the [GAIN/PL] control
counterclockwise to reduce the sensitivity so that the targets are easy to observe. However,
be careful not to overlook important small targets.

3.4.6 Suppress Sea Clutter [AUTO-SEA]
Procedures 1 Control the sea clutter returns on the radar display by turning the
[AUTO-SEA] control until targets can be easily observed.
Turning [AUTO-SEA] control clockwise suppresses sea clutter returns.
Turning [AUTO-SEA] control counterclockwise intensifies sea clutter returns.
The sea clutter suppression function suppresses sea clutter returns by decreasing the receiving
sensitivity on a short range.
Turning the [AUTO-SEA] control clockwise heightens the effect of sea clutter suppression.
However, be careful that excessive suppression causes low signal-strength targets such as
buoys and boats to disappear from the radar display.
Before sea clutter returns can be suppressed in accordance with their intensity, the automatic
sea clutter suppression mode must be selected by pressing the [AUTO-SEA] control. Use
this automatic mode when sea clutter returns vary in direction.
To change back to the manual mode, press the [AUTO-SEA] control again.
Note: The AUTO SEA (automatic sea clutter suppression) mode and the AUTO RAIN (automatic
rain/snow clutter suppression) mode cannot be used at the same time.
Using AUTO SEA (automatic sea clutter suppression function)
Procedures 1 Press the [AUTO-SEA] control.
AUTO SEA is selected, and SEA AUTO is indicated at the lower left of the radar
display. If AUTO SEA is selected, rotating the AUTO RAIN control and AUTO SEA
control can make fine adjustments manually.
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.

Turning [AUTO-RAIN] control clockwise suppresses rain/snow clutter returns.
Turning [AUTO-RAIN] control counterclockwise intensifies rain/snow clutter returns.
When the [AUTO-RAIN] control is turned clockwise, the rain/snow clutter suppression
function suppresses rain/snow clutter returns and gets targets hidden by rain/snow clutter
returns to appear on the radar display. However, be careful that excessive suppression may
cause small targets to be overlooked. Since the rain/snow clutter suppression function also
has the effect of suppressing sea clutter, the suppression efficiency improves when the
[AUTO-RAIN] control is used with the [AUTO-SEA] control. In general, turn the
[AUTO-RAIN] control fully to the left.
Before rain/snow clutter returns can be suppressed in accordance with their intensity, the
automatic rain/snow clutter suppression mode must be selected by pressing the
[AUTO-RAIN] control.
To change back to the manual mode, press the [AUTO-RAIN] control again.
Note: The AUTO SEA (automatic sea clutter suppression) mode and the AUTO RAIN (automatic

targets do not flicker and are easily identified on the chart, and the true bearing 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 pressing [AZI MODE] key, the own ship’s course is fixed pointing to the zenith of the PPI (0° on
range rings) points to the due north. 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 varies by the
same shift of own ship’s course. To change the course, press [AZI MODE] key several times to
select the Course-up mode, and set a new course.

initial bar length B shown on the INFORMATION LABEL.
Referring to the Calibration Curve I, obtain the relative attenuation d (A) for the value
A. The result of d (A) - d (B) indicates the current attenuation of transmitted power
compared with the initially specified value.
When d (A) - d (B) indicates attenuation of 10 dB or more (due to the end of
magnetron’s life), the transmitter system needs to be inspected by the service
engineer.

(Example) When the initial bar length B = 8 and the current bar length A = 6, the relative attenuation is
obtained as d (B) = 3.5 dB and d (A) = 7 dB according to the Calibration Curve I. Thus, d
(A) - d (B) = 3.5 dB. This proves that the current attenuation of transmitted power is about

3.11.3 Overview of Function Operations
The following outlines the operation of each function selected from the function setting menu:
[Page 1] [1] MODE (Mode)
· Selects the function name to be indicated at the lower left of the radar display when the function is
selected.
· When the setting is changed back to the factory setting, the initial value of the selected mode is
called.
· The following 11 modes are provided:
COAST: Use this mode to monitor a relatively short range, for example, bays and coasts
where many boats and ships are running. (Importance is attached to resolution.)
DEEPSEA: Use this mode to monitor a relatively long range, for example, the open sea.
(Importance is attached to long-range sensitivity.)
FISHNET: 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
sensitivity to moving targets lowers.)
STORM: 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 sensitivity slightly lowers.)
CALM: Use this mode when only a few rain/snow clutter returns or sea clutter returns are
detected.
RAIN: Use this mode when sea clutter is not strong but rain/snow clutter is strong.
(Importance is attached to rain/snow clutter suppression, and sensitivity slightly
lowers.)
BIRD: Use this mode to detect tens of seabirds at low altitude during coastal navigation
or hundreds of seabirds at high altitude during ocean navigation.
LONG: Use this mode to detect small targets at relatively long distance in the open sea.
BUOY: Use this mode to detect small targets like radio buoys in areas outside the sea
clutter area. (This mode displays targets of which detection probability is low.)
USER1: General mode used when the nine modes above are not applicable
USER2: General mode used when the nine modes above are not applicable

[Page 1] [4] Target Enhance
· Same function as TARGET ENHANCE in the Main Menu
3─123
[Page 1] [5] Auto SEA/RAIN (Auto STC/FTC)
· 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 control the afterimages of
unwanted waves.
· To control the afterimage of sea clutter, use the [SEA] control.
· To control the afterimage of rain/snow clutter, use the [RAIN] control.
· 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: 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.
AUTO SEA: 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.
Since rain clouds outside sea clutter areas are recognized as land, there is no effect
of suppressing rain/snow clutter.
AUTO RAIN: 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.

[Page 5] [1] Gain Offset
· Corrects sensitivity 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, sensitivity needs fine adjustment for always obtaining the highest
level.
· The sensitivity correction function saves the correction value set by the sensitivity control in each
function mode, so it can obtain the highest sensitivity without the sensitivity control being operated
when the function mode is changed.
· To set high sensitivity, set a value on the “+” side.
· To set low sensitivity, set a value on the “-” side.
· When the radar interference rejection level is increased, the noise level is lowered. Thus, set a
sensitivity correction value to the “+” side.
· When the video process mode 3SCAN CORR, 4SCAN CORR, or 5SCAN CORR is used, the noise
level is lowered. Thus, set a sensitivity correction value to the “+” side.
· When the video process mode REMAIN or PEAK HOLD is used, noise is hard to disappear. Thus,
set a sensitivity correction value to the “-” side.
[Page 5] [2] XMIT Repitation FREQ.
· Same function as in the TRX Setting of the RADAR Menu generally used
[Page 5] [3] Small Buoy Detection
· Reduces the loss of signal processing during detection of small targets.
OFF: Activates the general signal processing mode.
ON: Activates the small buoy detection mode that reduces the loss of signal processing.
[Page 5] [4] FishNet Detection
· Use this mode to detect small targets hidden by sea clutter returns.
· This function becomes more effective when the AUTO RAIN clutter suppression function is used
together.
OFF: Activates the general signal processing mode.
ON: Activates the fishnet detection mode.
