  • Page 3 CAUTIONS AGAINST HIGH VOLTAGE Radio and radar devices are operated by high voltages of anywhere from a few hundred volts up to many hundreds of thousands of volts. Although there is no danger with normal use, it is very dangerous if contact is made with the internal parts of these devices. (Only specialists should attempt any maintenance, checking or adjusting.) There is a very high risk of death by even a few thousand volts, in some cases you can be fatally electrocuted by just a few hundred volts.
  • Page 4 First aid ☆Note points for first aid Unless there is impending danger leave the victim where he or she is, then begin artificial respiration. Once you begin artificial respiration, you must continue without losing rhythm. (1) Make contact with the victim cautiously, there is a risk that you may get electrocuted. (2) Switch off the machinery and then move the victim away slowly if you must.
  • Page 5 ☆If the victim has a pulse but is not breathing (“Mouth to mouth” resuscitation) Figure 1 (1) Place the victim’s head facing backward (place something under the neck like a pillow). (2) Point the chin upward to widen the trachea. (3) Pinch the victim’s nose, take a deep breath, then put your mouth over the victim’s mouth and exhale completely, making sure that your mouth completely covers the victim’s mouth.
  • Page 6 ☆ If the victim has no pulse and is not breathing (Heart massage in combination with artificial respiration.) Figure 2 If the victim has no pulse, his or her pupils are dilated, and if you cannot detect a heartbeat, the heart may have stopped, beginning artificial respiration is critical.
  • Page 7 Preface Thank you for choosing the Model JRC JSS-2250/2500 (JSS-2250N/2500N) MF/HF radio equipment. The radio equipment can be used as a Global Maritime Distress and Safety System (GMDSS) radio device, compliant with international regulations, that provides emergency communications and standard communications capabilities for small and large ships.
  • Page 8 Before operation Concerning the symbols This manual uses the following symbols to explain correct operation and to prevent injury or damage to property. The symbols and descriptions are as follows. Understand them before proceeding with this manual. WARNING Indicates a warning that, if ignored, may result in serious injury or even death.

  • Page 10 Doing so may save the lives of the crews and passengers on the ship in distress. This equipment is used for both distress communication and routine communication. Contact JRC or our agent if any problem is observed in this unit during routine operation or inspection.
  • Page 11 CAUTION Do not use this equipment anyplace other than specified. Doing so may cause failure or malfunction. Do not turn the trimmer resistors or the trimmer capacitors on the PCB unit. Doing so may cause failure or malfunction. Do not install the equipment in a place near water or in one with excessive humidity, steam, dust, or soot.
  • Page 12 CAUTION A distress acknowledgement or a distress relay call can be transmitted from a received distress message stored in the log, but when sending such a call, follow the instructions of the ship's captain or officer in charge. Received distress message logs are automatically deleted after 48 hours to avoid accidental resending or other misoperation.
  • Page 13 Sending a Distress Call (Distress Alert) CAUTION When sending a distress call, follow the instructions of the ship's captain or officer in charge. Open the DISTRESS key cover on the NCM-2150 MF/HF CONTROLLER. Press and hold the DISTRESS key for 4 seconds to send the distress call. When the countdown is finished the screen below on the right is displayed, and after tuning the antenna to the frequency, the distress call is transmitted.
  • Page 14 After receiving acknowledgement, use the radiotelephone to request rescue. First, the responding station calls by radiotelephone. Communicate the following information to that station. Say "MAYDAY". Say "This is (name of your ship)". Tell the station the ship's Maritime Mobile Service Identity (MMSI) number, call sign, ship's position, nature of distress, and rescue requests.

  • Page 15: Receiving A Distress Call

    Receiving a Distress Call WARNING If a distress call is received, make sure to inform the ship's captain or officer in charge. Doing so may save the lives of the crew and passengers on the ship in distress. When a distress call is received, the distress message is displayed. The ALM lamp starts blinking, and an alarm gradually grows louder.
