  • Page 3 Safety Cautions Cautions for High Voltage High voltage of hundreds volts is used inside this equipment. Touching a component inside the unit is very dangerous. (Any person other than authorized service engineers should not maintain, inspect, or adjust the unit.) High voltages on the order of tens of thousand volts are most likely to cause instant deaths from electrical shocks.

  • Page 4: Emergency Measures

     Emergency Measures  Method of First-Aid Treatment Precautions for First-Aid Treatments Apply artificial respiration to the person who collapsed, minimizing moving as much as possible avoiding risks. Once started, artificial respiration should be continued rhythmically. (1) Refrain from touching the patient carelessly as a result of the accident; the first-aider could suffer from electrical shocks by himself or herself.
  • Page 5  Treatment to Give When the Patient Has a Pulse Beating but Has Ceased to Breathe ∗ Performing mouth-to-mouth artificial respiration (1) Bend the patient's face backward until it is directed to look back. (A pillow may be placed under the neck.) (2) Pull up the lower jaw to open up the airway.

Listen to the appeal of the Responding Check for response.
  • Page 7 Specific Procedures for Cardiopulmonary Resuscitation (CPR) 1. Check the scene for safety to prevent secondary disasters Are you OK? a) Do not touch the injured or ill person in panic when an accident has occurred. (Doing so may cause electric shock to the first-aiders.) b) Do not panic and be sure to turn off the power.
  • Page 8 b) If the injured or ill person is breathing, place him/her in the recovery position and wait for the arrival of the emergency services. • Position the injured or ill person on his/her side, maintain a clear and open airway by pushing the head backward while positioning their Roll gently in the opposite mouth downward.
  • Page 9 2) Perform chest compressions Compress with these • Perform uninterrupted chest compressions of 30 parts (the heels of at the rate of about 100 times per minute. both hands). While locking your elbows positioning yourself vertically above your hands. • With each compression, depress the chest wall to a depth of approximately 4 to 5 cm. b) Combination of 30 chest compressions and 2 rescue breaths 30 times 1) After performing 30 chest compressions, give 2 rescue...

If a medical patch or plaster is present, peel it off and then paste the pads. If the injured or ill person's chest hair is thick, paste the pads on the chest hair once, peel them off to remove the chest hair, and then paste new pads.

  • Page 17: Preface

    Preface Thank you for purchasing this JLN-720 Satellite Log from Japan Radio Co., Ltd.. This equipment is an SDME (Speed and Distance Measuring Equipment), complying with the regulations of IMO (International Marine Organization), measures and displays wide-range vessel speed over ground.

  • Page 18: Pictorial Indication

     Pictorial Indication  Meanings of Pictorial Indication Various pictorial indications are included in this manual and are shown on this 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.

  • Page 19: Usage Precautions

     Usage Precautions  DANGER Never remove the cover of this equipment. Touching the high-voltage section inside may cause an electric shock. Before conducting inspection, maintenance or parts replacement, make sure to turn off the power and breaker. Failure to comply may cause an electric shock, fire or an equipment fault. Make sure to turn the breaker off since voltage is still outputted from the distribution processor even after the displays are turned off.
  • Page 20 A fire, an electric shock, or a malfunction may occur. For maintenance, inspection of the internal section of the equipment, request the service to the store, nearest JRC agent, JRC marine service department, sales department, regional office, branch or sales office.
  • Page 21 Failure to comply may result in an electric shock. When the power cable is damaged (exposed cable conductor, broken cable, or torn capsule), request replacement to the store, nearest JRC agent, JRC marine service department, sales department, regional office, branch or sales office.
  • Page 22 Disposal of the battery must obey the local laws or rules. Before disposal of used lithium batteries, make sure the + and – terminals are insulated by tape. Otherwise, heat, rupture or fire may occur due to a battery short. When installing the cable that is attached to the GPS compass sensor, do not bend the cable to a sharp angle, twist it, or install it in such a manner that some force is applied to the cable.
  • Page 23 Electrical work for this equipment must be requested to the store, nearest JRC agent, JRC marine service department, sales department, regional office, branch or sales office. Conducting electrical work by anyone other than the specialized maintenance staff may result in an accident or an equipment fault.
  • Page 24 Do not use or leave the equipment under direct sunlight for a long time or in the temperatures above 55°C. (except wing display) Otherwise, fire or a malfunction may occur. Do not install the equipment in a place under the influence of water, humidity, vapor, dust or soot.
  • Page 25 Do not carry out operation of touch panel by a sharp object. Otherwise, the screen may be damaged. If power outage occurs inside of the ship during the operation of the satellite log, the image may be disturbed or may not be displayed. In this case, reconnect the power supply.
