Cautions to be Used during Operation

●

Do not touch the insides of the scanner, transmitterreceiver and display unit.

Touching any high voltage area, you will get an electric shock. For maintenance, inspection and adjustment of internal parts of these equipment, consult with our sales office or distributor in your district.

Since the scanner radiator rotates, do not approach it.

The scanner may start rotating suddenly, and consequently any person may be struck and be injured. We recommend you to install the scanner radiator on the roof of the wheel house, flying bridge, trestle, radar mast or any other high position so that no person can approach it. When servicing the scanner, set the scanner safety switch to the “OFF” position.

SCANNER RADIATION HAZARD Never look up the antenna from which radiation is being output from a distance less than the following.

Injury may result from exposure to radiation produced by the antenna (particularly effects to the eyes) at a distance from the central front face of the antenna less than:

0.6 meter for NKE-1059/1052 (Radiation power density of 10 W/m2)

1.1 meter for NKE-1079/1075 (Radiation power density of 10 W/m2) 25 cm for NKE-1079/1075 (Radiation power density of 100 W/m2)

Install the scanner at any place higher than any person.

If being exposed directly to electric wave at close range, you may suffer adverse influence.

When approaching the scanner for maintenance or inspection, set the power switch of the display unit to the “OFF” or “STBY” position.

If being exposed directly to electric wave to close range, you may suffer adverse influence.

WARNING

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 and 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.

◆◆◆◆◆◆◆◆◆

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 his 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, close 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 minute (blocking his nostrils).

(4) Carefully watch that he has recovered his natural breathing and stop 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. / q 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 /

or, pinch his nostrils with your fingers to prevent air from leaking. / e

(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

Page 10

– viii –

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 2 cm (Repeat compressing his breast 50 times or so a minute). (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 5 times while the other person blow into his mouth once, and they shall repeat this combination. (Perform the cardiac massage and mouth-tomouth 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 treatments.

1.1 FUNCTIONS

This equipment is a high-performance radar equipment consisting of a scanner unit, a transmitterreceiver unit and a 29-inch color raster-scan CRT display unit. This radar complies with the current performance standards of the IMO.

1.1.1 Functions of This System

The JMA-9800 ARPA series is a color radar system designed to comply with the international standards of the IMO. The main functions include; sea clutter and rain/snow clutter suppression, sensitivity adjustment, interference reflector, bearing and range measurement using a trackball, fixed/variable range markers, and electronic bearing line, and ARPA functions (automatic/manual target acquisition and tracking, vector and trail displays, alarm displays and trial maneuvering). In addition, the equipment has the functions of color display setting (4 views), own track display, NAV line and marker displays, TM (True Motion) presentation, Self-diagnostic facilities, and radar performance monitoring (Performance Monitor). As an option, the radar of 3-units switchover function (Interswitch) is also available.

1.1.2 ARPA Functions

The ARPA functions that the JMA-9800 series incorporates will be outlined below.

[!!] First Stage: Target Detection from Radar Information

This work corresponds to plotting targets by hand on the radar display. Assume that a ship is approaching the own ship. You can catch the ship on the radar. Signals from the ship are processed with the data processor and are transferred to the computer as signals of bearing and range related to the own ship. In this stage, the system has the functions to quantize radar information, to reject noises, to eliminate any information other than ship information and to transfer necessary position data of ships to the computer.

[@@] Second Stage: Target Tracking

Targets are plotted at intervals of 3 to 6 minutes with the radar, but tracking on this system is to plot them electrically at intervals of fixed times. This means to compare target position data to be detected every moment with those detected previously so as to check if they are of the same target and also to save data of the target in its file so as to calculate changes of position data of the target.

[##] Third Stage: Judgment of Existence of Ship in Danger of Collision

In this stage, the system calculates speeds and courses of a target ship from ever-changing position data of the target ship obtained in the previous stage so as to judge existence of any danger of collision. After the calculation, the system can easily calculate the Closest Point of Approach (CPA) to the own ship and the time required to reach the CPA (TCPA = Time to CPA). Both the CPA and the TCPA are compared with the preset values previously set according to the situations of the own ship so as to judge existence of any danger of collision.

1.1 FUNCTIONS

[$$] Fourth Stage: Indication

The above information must be informed to the officer maneuvering the own ship. A variety of indicating methods are available including CRT display and numerical indicator, and various data are available. This system indicates unprocessed video, vectors (to be selected from true vector and relative vector) of other ships and identification marks of danger ship or safe ship for these ships on the usual radar scope. When the target ship is a danger one, the system will sound an alarm and turns on the alarm lamp to alert the officer.

1 – 3

1.2 FEATURES

Target Detection by Latest Signal Processing Technology

The system employs the latest adaptive clutter suppression 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.

Key Arrangement for Higher Operability

The basic and main functions of the radar can be operated with the minimum necessary keys, ensuring quick action even in case of emergency. Other various useful functions are also available by the use of the simple keys behind a cover and the menu selection on the display. In the case that two or more operators operate the radar equipment, each operator can register the operating conditions that are most favorable to him/her and can be recalled and set momentarily (Personal code function is built-in).

Advanced Technology Based ARPA Functions Provided as Standard

The ARPA target acquisition and tracking performance is enhanced by the use of the most advanced radar signal processing and tracking technologies, ensuring stable operation in target tracking under clutter.

● Acquisition and tracking of 50 targets

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

● Trial maneuvering functions provided

● Simultaneous indication of other ships’ data

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.

Various Functions

● TRAILS (Other ship’s track display)

● NAV lines

● TM (True Motion display)

● Head-up/North-up/Course-up display

● Own ship’s track display

● Guard Zone function

1.2 FEATURES

Compact Design and Low Power Consumption

The radiator structure making the most of wind power contributes to the substantial reduction in size and power consumption of the S band scanner unit.

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)

By additionally installing an interswitch PC board, up to 3-units of the JMA-9800 series radar equipment can be combined and switched over by simple operation.

1.6 COLLISION AVOIDANCE

……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 constitues 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.1.19 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.

Fig.1.19 Navigation Pattern

……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.

1.6 COLLISION AVOIDANCE

……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.1.20 shows a diagram called “Collision Triangle”.

Page 58

1 – 29

……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.1.21. 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.

Fig.1.21 Relative Vector and True Vector

……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 movements. 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 ships, which are manually plotted, is limited and it takes several minutes to measure those.

Example 1

● If the installed indicator is used in an ambient condition of 0º or less, the power to the radar should be turned on more than 60 minutes after the power in the ship is turned on.

● Wait approximately 6 seconds before turning on the power again.

● A malfunction may occur if the power in the ship is instaneously interrupted during operation of

the radar. In this case, the power should be turned on again.

● Immediately after the radar is installed, if the system is not used for a long time, or after the magnetron is replaced, warm-up the equipment in the standby mode for 20 to 30 minutes before setting it to the transmit mode.

● If the warm-up time is short, the magnetron may cause 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, reset the system to the standby mode immediately and maintain it in the standby mode for 5 to 10 minutes before restart the operation. Repeat these steps until the operation is stabilized.

3.3 PREPARATION

……Tuning TUNE ………………………………………………………

This control is used to tune the receiver. If the receiver is detuned from the best level, the receiving sensitivity falls, and the targets on a long range or the small targets on a short range may be overlooked. In manual tuning, rotate the [TUNE] control clockwise or counterclockwise and adjust so that the target echoes are the clearest. If no suitable target is present, adjust the control so that the tuning indication bar-graph at the upper left of the radar display is maximized. After setting the radar to the TRANSMIT mode, it takes about 10 minutes until the oscillation frequency of the magnetron is stabilized. Therefore, tune the receiver once again after about 10 minutes. For automatic tuning, setting “2.TUNE” to “AUTO” in the AUTO Menu. (Refer to page 3 - 5)

……Sensitivity Control GAIN …………………………………………

This control is used to control the radar receiving sensitivity. Clockwise rotation of the [GAIN] control increases receiving sensitivity and extends the radar observation range. If the sensitivity is too high, the receiver noise will increase to reduce the contrast of the targets with the background video and make the targets obscure on the display. To observe densely crowded targets or the targets on a short range, rotate the [GAIN] control counterclockwise to reduce the sensitivity so that the targets are easy to observe. Be careful not to overlook small and important targets.

……Display Brilliance Control BRILL ………………………………

This control is used to adjust the brilliance of the entire display. Clockwise rotation of the [BRILL] control increases the brilliance of the entire display. Adjust the [BRILL] control to obtain the best-to-see display with optimum brilliance.

3.3 PREPARATION

……Contrast Control BRILL VIDEO …………………………………

The contrast of the radar video display can be adjusted in four levels. Each time the [BRILL VIDEO] switch is pressed, the contrast will change the mode in the following order: ///

The current mode is indicated at the lower right of the radar display. (The VIDEO indication will change to the PANEL indication in several second.) Adjust the [BRILL VIDEO] switch to obtain the best-to-see video with optimum contrast.

……Sea Clutter Suppression SEA …………………………………

This control is used to reduce the receiving sensitivity on a short range to suppress the sea clutter returns. Clockwise rotation of the [SEA] control can suppress sea clutter returns more effectively. Be careful not to suppress sea clutter excessively. Otherwise, small buoys and boats may disappear from the radar display. When setting to in the AUTO Menu, sea clutter returns can be suppressed depending on their intensity levels. This setting is used for the case that the sea clutter returns are different in their directions. When setting to in the AUTO Menu, the mode is changed into the MANUAL mode. (Refer to page 3 - 3)

Note: It is impossible to use both the AUTO SEA mode and the AUTO RAIN mode at the

same time.

Attention

Page 84

3 – 13

……Rain/Snow Clutter Suppression RAIN …………………………

This control is used to suppress rain or snow clutter returns. Clockwise rotation of the [RAIN] control makes the targets clearer that may be hidden among rain/snow clutter returns. Be careful not to overlook small targets in the clutter. This control also has the effect of reducing sea clutter, so that it is more effective to use this control together with the [SEA] control. Rotate the control counterclockwise to the maximum in the normal condition.

When setting to in the AUTO Menu, rain/snow clutter can be suppressed depending upon the intensity level. When setting to in the

AUTO Menu, the mode is changed into the MANUAL mode. (Refer to page 3 - 4)

Note: It is impossible to use both the AUTO RAIN mode and the AUTO SEA mode at the

same time.

……Brilliance Control ……………………………………………………

Press each of the following switches:

The BRILLIANCE switches [PANEL], [BRILL VIDEO] and [BRILL ARPA] are used to adjust the brilliance of the panel, video and ARPA markers. Each time a switch is pressed, the brilliance is increased by one level up to 4 or 5 levels. When the maximum level is reached, the brilliance is reset to the original level.
