  • Page 3: 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 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. 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. Tilt the victim's head back as far as this face looks back. (A pillow may be inserted his neck.) Push his jaw upward to open his throat wide (to spread his airway). 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.

  • Page 7: Preface

    PREFACE Thank you very much for purchasing the JRC marine radar equipment, JMA-9100 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 ● 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 ● 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.
  • Page 10 Make sure to turn off the scanner safety switch. Failure to comply may result in injuries caused by physical contact with the rotating scanner. Never directly touch the internal components of the scanner or indicator. Direct contact with these high- voltage components may cause electrocution.
  • Page 11 Microwave radiation level: Keep out from a distance closer than that specified below for each type of scanner when it is transmitting. Being within the specified distance from the center of the front face of the scanner may cause microwave exposure which could result in injuries (especially of the eyes).
  • Page 12 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 Use Target Tracking (TT) function 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 tracking target information may cause accidents. Tracking target information such as vector, target numerical data, and alarms may contain some errors.
  • 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.
  • 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.
  • Page 16 Do not change the quantization level settings unless absolutely necessary. If set at an inappropriate value, the target acquisition or target tracking function deteriorates, and this may lead to accidents.

  • Page 28: Glossary

    GLOSSARY This section describes the main terms used for this equipment and general related maritime terms. Acquisition/Activation zone A zone set up by the operator in which the system should automatically acquire radar targets and activate reported AIS targets when entering the zone. Activated target A target representing the automatic or manual activation of a sleeping target for the display of additional information.
  • Page 29 CPA/TCPA The distance to the Closest Point of Approach/Time to the Closest Point of Approach. Limits are set by the operator and are related to own ship. Course Through Water The direction of the ship's movement through the water DRIFT The current velocity for manual correction or the current speed on the horizontal axis of the 2-axis log is displayed.
  • Page 30 Lost AIS target A target symbol representing the last valid position of an AIS target before the reception of its data was lost, or its last dead-reckoned position. Lost tracked One for which target information is no longer available due to poor, lost or obscured signals.
  • Page 31 Relative Motion A display on which the position of own ship remains fixed, and all targets move relative to own ship. RM(R) Relative Motion. Relative Trails. RM(T) Relative Motion. True Trails. Rate Of Turn Change of heading per time unit. Route A set of waypoints.
  • Page 32 Trial manoeuvre A graphical simulation facility used to assist the operator to perform a proposed maneuver for navigation and collision avoidance purposes.
