  • 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-5900 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 carry out internal inspection or repair work of the equipment by users. 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.
  • Page 10 WARNING Never directly touch the internal components of the scanner 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"...
  • Page 11 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 cleaning the display screen, do not wipe it too strongly with a dry cloth.
  • Page 12 CAUTION 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. Normally, use the automatic tune mode. Use the manual tune mode only when best tuning is not possible in the automatic tune mode due to deterioration of magnetron.
  • Page 13 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. Use target tracking function only as a navigation aid.
  • Page 14 CAUTION If a great value is set as a condition for deciding targets as identical, a tracking target near an AIS target is regarded as identical to the AIS target and it may not be displayed any more. For example, when a pilot boat (which is a small target not being tracked) equipped with an AIS function approaches a cargo ship as a tracking target not equipped with an AIS function, the tracking target symbol of the cargo ship may...
  • Page 15 CAUTION Any adjustments must be made by specialized service personnel. Failure to comply may result in accidents or equipment failure. 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.

    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.

    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.

This interference pattern consists of a number of spots which appear in various forms.
