  • Page 3 General Information Thank you for purchasing the JFE-680 Echo-Sounder manufactured by Japan Radio Co., Ltd. The JFE-680 conforms to the IMO (International Maritime Organization) performance standards, enabling seabed displays and digital depth displays. Before attempting to operate this equipment, please read this instruction manual thoroughly to ensure correct and safe operation in accordance with the warning instructions and operation procedures.
  • Page 4 Before You Begin Symbols Used In This Manual To ensure that the equipment is used safely and correctly, and that the operator and third parties are not exposed to danger or damage, pictograms are used in this manual and on the equipment itself.
  • Page 5 Usage Hints Do not remove the cover of this set. Otherwise, you may touch a high-voltage part and suffer from an electrical shock. Do not dismantle or modify this equipment. Failure to observe this warning may result in fire, electric shock, or damage.
  • Page 6 There are no customer-serviceable parts inside. Unauthorized inspections and repairs could cause fires and electrical shock hazards. Please call our field representative or your nearest JRC office for inspection and repair services. Use only the specified fuses.
  • Page 7 Please contact JRC or its agent for the electrical installation of this equipment. Electrical installations carried out by other than the qualified staff may result in faulty operation. Do not store or operate the equipment where subject to temperatures more than 55℃ or less than -15℃. High temperature may cause failures.
  • Page 8 When removing the power cord, be sure to remove the power cord terminal correctly. If the power cord is pulled, the cord may be damaged resulting in a fire or an electrical shock. Do not install the units on the place being poor ventilation.

  • Page 10 Explanation of Terms Beam angle: The angle that sound waves spread out from the transducer. Sound waves spread out in a conical manner taking the center of the bottom surface of the transducer at the apex of the cone. Bubbling: The phenomenon where the image of the seabed is interrupted due to air bubbles caused by the ship's hull or the propeller during a voyage.

  • Page 81 Seabed Quality Change Rock In case of a hard seabed composed of rocks etc., its return trails long, as shown in right chart. In case of a soft seabed made of mud, seaweed, etc., they poorly reflect an ultrasonic wave to result in thin recording of the seabed with short trail.
  • Page 82 Abrupt-Sloped Seabed Sidelobe False echo A dim echo may sometimes appear along an abrupt slope of seabed, as if it were floating above the slope, when recording. In case of flat seabed, thin second return of seabed may sometimes appear, which is slightly below the actual seabed.
  • Page 83 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. In particular, a seabed with abrupt slope and heavily rugged surface provided an echo very difficult to display on the recording.
