◆◆◆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.

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.

- iv -

WARNING

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).

NKE-2103/2254 (radiation levels: 10 W/m2): 0.6 m

NKE-1130 (radiation levels: 10 W/m2): 1.1 m

NKE-1130 (radiation levels: 100 W/m2): 25 cm

Make sure to install the scanner at a place higher than

human height.

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.

- v -

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.

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.

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 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.

CAUTION

- vi -

CAUTION

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

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.

- vii -

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 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.

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.

- viii -

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.

• 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.

Note: ARPA/ATA Process Unit must be fitted on ships compliant to IMO.

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.

power again.

Attention

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.

z 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.

z 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
