◆◆◆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.

Page 6

☆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.

DANGER

When conducting maintenance work on the antenna, make sure to turn its main power off. Failure to comply may result in electrocution or injuries.

- iii -

Page 10

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

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 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.

DANGER

WARNING

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.

- iv -

Page 11

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 ( radio-density : 10 W/m2): 0.6 m

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

WARNING

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.

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.

WARNING

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.

- vi -

Page 13

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. ATA 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

CAUTION

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.

- vii -

Page 14

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 is properly operating. Therefore, never use this function unless you wish to check ATA 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 ATA performance.

Make sure to shut off the main power before replacing parts. Failure to comply may result in electrocution or

CAUTION

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 -

Page 15

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.

CAUTION

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.

1.2 FEATURES

Realization of Easy-to-see Screen with High Resolution

The 15-inch color LCD with high resolution of 1024 × 768 pixels can display radar images of 180 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 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 30 targets.

• Hazardous conditions are represented by shapes and colors of symbols as well as sounds.

• 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, the data of coastlines, objects such as buoys, and own ship's tracks/ATA 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. 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 - 2

Page 36

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-64) is needed separately.

Simplified Inter-switch Operation (Option)

If an simplified inter-switch unit (option) is installed, up to two JMA-5200 radars can be switched over by performing simple operation. * An simplified inter-switch option is required separately.

Various Functions

• RADAR TRAILS (Other ship’s track display)

• TM (True Motion) display

• Head-up/North-up/Course-up display

• Own ship’s track display

• Guard Zone function

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 BASIC OPERATIONS

3.4.6 Suppress Sea Clutter [AUTO-SEA]

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.

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.

3.4 BASIC OPERATIONS

3.4.7 Suppress Rain/Snow Clutter [AUTO-RAIN]

When using the [AUTO RAIN] 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 [AUTO RAIN] function, make sure to

choose the most appropriate image noise suppression level.

Procedures 1 Control the rain/snow clutter returns on the radar display by turning the

[AUTO-RAIN] control until targets can be easily observed.

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

rain/snow clutter suppression) mode cannot be used at the same time.

Using AUTO RAIN (automatic rain/snow clutter suppression function):
