  • Page 3: Safety Cautions

    Safety Cautions Cautions for High Voltage High voltages, ranging from several hundreds to tens of thousands of volts, are used in electronic apparatus, such as radio and radar instruments. These voltages are totally harmless in most operations. However, 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.

A person is collapsing. - Secure the safety of the surrounding area. - Secure the safety of the surrounding area. - Prevent secondary disasters. - Prevent secondary disasters. Listen to the appeal of the Responding Check for response.
  • Page 5 Specific Procedures for Cardiopulmonary Resuscitation (CPR) 1. Check the scene for safety to prevent secondary disasters 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.

Cardiopulmonary resuscitation (CPR) (combination of chest compressions and rescue breaths) a) Chest compressions 1) Position of chest compressions • Position the heel of one hand in the center of the chest, approximately between the nipples, and place your other hand on top of the one that is in position. 2) Perform chest compressions Perform uninterrupted chest compressions of Compress...
  • Page 7 When to stop cardiopulmonary resuscitation (CPR) a) When the injured or ill person has been handed over to the emergency services b) When the injured or ill person has started moaning or breathing normally, lay on the side in a recovery position and wait for the arrival of emergency services.
  • Page 8 11. Electric shock (defibrillation) a) If the AED determines that electric shock is needed, the voice prompt saying, "Shock is needed" is issued and charging starts automatically. b) When charging is completed, the voice prompt saying, "Press the shock button" is issued and the shock button flashes. Press the shock button.

    This information is gained by using ultrasonic waves sent from the transducer that are then reflected off the sea bottom and picked up again by the transducer. The JFE-700 also has the following functions: (1) depth alert, (2) power fail alert, (3) output of depth data, (4) output of depth and power fail alerts.

  • Page 88 In case of flat seabed, thin second return of seabed may sometimes appear, which is slightly below the actual seabed. In either case, the dim or thin echoes are false and produced by side lobes of ultrasonic beam from the transducer. Any false echo is thinner than and parallel to a real echo. The echo of a seabed with abrupt slope is recorded as a lone difficult to see and less discriminative, since it tends to accompany with a false echo due to the side lobe and the inherent property of directivity.
