  • Page 3 ◆◆◆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 4 ◆◆◆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 5 ☆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 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).

  • Page 7: Preface

    PREFACE Thank you very much for purchasing the JRC marine radar equipment, JMA-5200 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 LCD display unit and a scanner unit as its main units.

  • Page 8: Before Operation

    ●Before Operation● Pictorial Indication Various pictorial indications are included in this manual and are shown on these equipment so that you can operate them safety and correctly and prevent any danger to you and/or to other persons and any damage to your property during operation.

  • Page 9: Precautions

    ●PRECAUTIONS● DANGER 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.
  • Page 10 DANGER Make sure to turn off the antenna operation switch. Failure to comply may result in injuries caused by physical contact with the rotating antenna. WARNING Never directly touch the internal components of the antenna, receiver/transceiver, or indicator. Direct contact with these high-voltage components may cause electrocution.
  • Page 11 WARNING 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).
  • Page 12 WARNING 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.
  • Page 13 CAUTION 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.
  • Page 14 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.
  • Page 15 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.
  • Page 16 CAUTION Do not change the quantization level settings unless absolutely necessary. If set at an inappropriate value, the acquisition or tracking function of ATA deteriorates, and this may lead to accidents. - x -...

    5.1.1 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 constitutes 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 223 5.1 PREPARATION 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 282 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 display, 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.

  • Page 283: Radar Wave With The Horizon

    6.1 RADAR WAVE WITH THE HORIZON RADAR WAVE WITH THE HORIZON Radar beam radiation has the nature of propagating nearly along the curved surface of the earth. The propagation varies with the property of the air layer through which the radar beam propagates. In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer than the distance to the optical horizon.
  • Page 284 D (nm) Height of Target Height of Radar Scanner Detective Range Figure 6.1 When the height of own ship’s scanner is 10 m for instance, A target that can be detected at the radar range of 64 nm on the radar display is required to have a height of 660 m or more.

  • Page 285: Strength Of Reflection From The Target

    6.2 STRENGTH OF RELECTION FROM THE TARGET STRENGTH OF REFLECTION FROM THE TARGET The signal intensity reflected from a target depends not only on the height and size of the target but also on its material and shape. The echo intensity from a higher and larger target is not always higher in general. In particular, the echo from a coast line is affected by the geographic conditions of the coast.

  • Page 287: False Echoes

    6.4 FALSE ECHOES FALSE ECHOES The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes appear by the following causes that are well known: [I] Shadow When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or mast.
  • Page 288 [IV] False Echo by Multiple Reflection When there is a large structure or ship with a high vertical surface near own ship as shown in Figure 6.5, multiple refection returns may appear on the radar display. These echoes appear in the same intervals, of which the nearest echo is the true echo of the target.

The SART is designed to operate in the 9 GHz frequency band.

    Vector Constant Attention Do not change the set value carelessly. The vector constant shall be set to 5 normally. If the vector constant value is higher, a target’s vector will be better followed up when the target and own ship change their course or speed, but the vector accuracy will be lower on the contrary.
  • Page 365 8.5 Adjustments Video TD Level CAUTION Do not change the set quantization level carelessly.
