◆◆◆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. →1

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
→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

☆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●

DANGER

Never carry out internal inspection or repair work of the
equipment by users.

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.

Make sure to turn off the scanner safety switch. Failure to
comply may result in injuries caused by physical contact
with the rotating scanner.

Do not touch the radiator. Even if the power is turned off,
the radiator may be rotated by the wind.

- iii -

WARNING

Never directly touch the internal components of the
scanner 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 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.

Microwave radiation level:
Keep out from a distance closer than that specified below

for each type of scanner when it is transmitting. Being
within the specified distance from the center of the front
face of the scanner may cause microwave exposure which
could result in injuries (especially of the eyes).

WARNING

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 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.

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.

When conducting maintenance work, make sure to turn off
the power and unplug the power connector J1 of the radar
process unit 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.

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.

- v -

CAUTION

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.

Normally, use the automatic tune mode.
Use the manual tune mode only when best tuning is not

possible in the automatic tune mode due to deterioration of
magnetron.

If the gain is too high, unnecessary signals including
receiver noise and false video 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.

When using the sea clutter suppression 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 sea clutter suppression function, make
sure to choose the most appropriate image noise
suppression level.

When using the rain / snow clutter suppression function,
never set the suppression level too high canceling out all
image noises from the rain or snow at the 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 rain / snow clutter suppression function,
make sure to choose the most appropriate image noise
suppression level.

- 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.

Use target tracking 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.

In setting an automatic acquisition zone, it is necessary to
adjust the gain, sea clutter suppression and rain clutter
suppression to ensure that target echoes are displayed in
the optimum conditions. No automatic acquisition zone
alarms will be issued for targets undetected by the radar,
and this may cause accidents such as collisions.

Target Tracking Function Test is provided to test if the
target tracking function is operating normally. Thus, do not
use the function except when you test the target tracking
function.

In particular, if the operation test mode is used during
navigation, pseudo targets appear on the radar display and
they are confused with actual targets.

Do not use the mode during navigation.
Otherwise, an accident may result.

- vii -

CAUTION

If a great value is set as a condition for deciding targets as
identical, a tracking target near an AIS target is regarded as
identical to the AIS target and it may not be displayed any
more.

For example, when a pilot boat (which is a small target not
being tracked) equipped with an AIS function approaches a
cargo ship as a tracking target not equipped with an AIS
function, the tracking target symbol of the cargo ship may
not be displayed any more.

Since these alarms may include some errors depending on
the target tracking conditions, the navigation officer
himself should make the final decision for ship operations
such as collision avoidance.

Making the final navigation decision based only on the
alarm may cause accidents such as collisions.

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.

Optimal values have been set for Video Level and Vector
Constant; therefore, never change their values unless
absolutely necessary. Failure to comply may result in
accidents that would lower target tracking performance.

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.

- viii -

CAUTION

Any adjustments must be made by specialized service
personnel.

Failure to comply may result in accidents or equipment
failure.

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.

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.

1.2 FEATURES

Realization of Large, Easy-to-see Screen with High Resolution

The 23.1-inch color LCD with high resolution of 1280 × 1024 pixels can display radar images of 320 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 Target Tracking (TT) Functions

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 7 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 /
target tracks / AIS 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.
Creation / display of marks and lines (up to 2000 items).
Use of the optional plotter function enables the own track display distinguished by using 7 different colors,
creation of marks and lines (up to 20000 items) and the settings of waypoints / courses.

Easy Operation with GUI

All the radar functions can be easily controlled by simply using the trackball and 2 switches to operate the
buttons shown on the radar display.

Improved Day / Night Mode

Five types of background colors are available in Day / Dusk / Night mode.
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.

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.

Easy Interswitch Operation (Option)

If an interswitch unit (option) is connected, up to four JMA-5900 radars can be switched over by
performing simple operation.
* An interswitch (NQE-3141) is needed separately.

Various Functions

• RADAR Trails

• TM (True Motion) display

• Head-up / North-up / Course-up display

• Own ship’s track display

• Automatic Acquisition / Activation function

3.2.1 Adjust Monitor Brilliance [BRILL]

Procedures 1 Obtain the best-to-see display with optimum brilliance by turning the

[BRILL] dial at the lower right of the LCD monitor.

Turning the [BRILL] dial clockwise increases the brilliance of the entire display.
Conversely, turning the [BRILL] dial counterclockwise decreases the brilliance of the
entire display.
In consideration of the ambient brightness, adjust display brilliance that is high
enough to easily observe the radar display but does not glare.

3.2.2 Change Observation Range [RANGE + / - ]

Procedures 1 When increasing the observation range, press the [RANGE+] key.

Increasing the observation range will enable a wider range to be observed.
However, a video image is small and the ability to detect targets near own ship
decreases. Therefore, when observing the vicinity of own ship, use the smaller
observation range.

2 When decreasing the observation range, press the [RANGE-] key.

Decreasing the observation range will enable the vicinity of own ship to be enlarged.
However, caution must be taken because video images of the area beyond the
observation range cannot be displayed.
