  • Page 1 MARINE RADAR EQUIPMENT INSTRUCTION MANUAL...
  • Page 3 PREFACE Thank you very much for purchasing the JRC marine radar equipment, JMA-9800 ARPA series. This equipment is a marine radar equipment designed to obtain safe operation of marine ships. This equipment consists of a radar signal transmitter-receiver unit, a CRT display unit and a scanner unit as its main units.
  • Page 4 Before Operation Pictorial Indication Various pictorial indications are included in this manual and are shown on these equipment so that you can operate them safely and correctly and prevent any danger to you and/or to other persons and any damage to your property during operation. Such indications and their meanings are as follows. Please understand them before you read this manual: This indication is shown where any person is supposed to be in danger WARNING...
  • Page 5: Cautions To Be Used During Operation

    Cautions to be Used during Operation WARNING Do not touch the insides of the scanner, transmitter- receiver 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.
  • Page 6 CAUTION Use these radar only as assisting devices for navigation. Also, the officer should make the final decision for maneuvering by himself. Use ARPA only as assisting device for navigation. Also, the officer should make the final decision for maneuvering by himself.
  • Page 7: Precautions Before Operation

    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.
  • Page 8: First-Aid Treatments

    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.
  • Page 9: When Pulse Is Beating But Breathing Has Stopped

    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.
  • Page 10: When Both Pulse And Breathing Have Stopped

    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).

  • Page 56: Collision Avoidance

    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.
  • Page 57: Basic Concept Of Collision Avoidance

    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.
  • Page 58: Relative Vector And True Vector

    ……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 radar operator has a role of interpreting the radar displays to provide his best aid in maneuvering the ship. For this purpose, the operator has to observe the radar displays after fully understanding the advantages and disadvantages that the radar has. For better interpretation of radar displays, it is important to gain more experiences by operating the radar equipment in fair weathers and comparing the target ships watched with the naked eyes and their echoes on the radar display.

    1. GENERAL 1.1 Outline The Interswitch Kit enables all possible interconnections between two or more radar display units and two or more scanner units installed on the bridge of a ship that have different characteristics. The NQE-3015N Interswitch Kit is used for the JMA-9800 series radar system and it is capable of switching over interconnections between three display units and three transmitter-receiver/scanner units (hereinafter called “MTR”).

    REFERENCES Pre-heat Time after Pattern Selection After switching over the interswitch patterns, it is necessary to wait for the time as mentioned below because the pre-heat time is different from the previous interconnection between the MTR and the display unit. This measure is taken for protecting the electronic tube emitting radar pulses. (a) Not changed to the new interconnection condition:......No preheat time (b) Changed to the new interconnection condition.
  • Page 337 The Slave Display Unit will not change the radar video even if the tuning control is adjusted because the tuning is controlled by the Master Display Unit. The tuning indicator at the upper left of the display will show “SLAVE”. The change of the range scale on the Slave Display Unit depends upon the range scale on the Master Display Unit.
