AMWUT665Handheld VHF Marine Radio

RADIO VHF MARITIME FLOTTANTE OWNER’S MANUAL GUIDE D’UTILISATION FLOATING VHF MARINE RADIO MHS338BT MAKING A DISTRESS CALL Lift the red cover. Press and hold the DISTRESS key for three seconds. Your radio transmits your ship’s location every few minutes until you receive a response. NOTE: If the radio displays Enter User MMSI, cancel the automatic distress call and make a normal voice distress call. Making a Voice Distress Call Speak slowly - clearly - calmly. For future reference, write your ship’s name & call sign here: 1. Make sure your radio is on. 2. Press the 16/P key to switch to Channel 16 (156.8 MHz). (If the corner of the display does not show 16, press the 16/P key again until it does.) 3. Press the PUSH-TO-TALK key and say: “MAYDAY -- MAYDAY -- MAYDAY.” 4. Say “THIS IS {name of your ship (three times)} and call sign/ship registration number (once).” 5. Repeat “MAYDAY {name of your ship}” once. 6. Tell where you are: (what navigational aids or landmarks are near, or read the latitude and longitude from your GPS). 7. State the nature of your distress (e.g. are you sinking, medical emergency, man overboard, on fire, adrift, etc. ). 8. State the type of assistance you need (medical, towing, pumps, etc.). 9. Give number of persons aboard and conditions of any injured persons. 10. Estimate present seaworthiness of your ship (e.g. how immediate is the danger due to flooding or fire or proximity to shore). 11. Briefly describe your ship, giving ship name (e.g. “Blue Duck is 32 foot cabin cruiser, white hull, blue deck house”). 12. Say: “I WILL BE LISTENING ON CHANNEL 16.” 13. End message by saying “THIS IS {name or call sign of your ship}, OVER.” 14. Release the PUSH-TO-TALK key and listen. If you do not get an answer after 30 seconds, repeat your call, beginning at step 3, above. Lift the red cover and press the white DISTRESS button underneath. FAIRE UN APPEL DE DÉTRESSE Soulevez le couvercle noir. Maintenez DISTRESS enfoncé pendant trois secondes. Votre radio transmettra l’emplacement de votre bateau toutes les quelques minutes jusqu’à ce que vous receviez une réponse. Remarque : Si la radio affiche Enter User MMSI, annulez l’appel de détresse automatique et effectuez un appel de détresse vocal normal. Faire un appel de détresse Parlez lentement – clairement – calmement. Pour toute référence ultérieure, écrivez ci-dessous le nom et l’indicatif d’appel de votre bateau: 1. Vérifiez si votre radio est en marche. 2. Appuyez sur la touche 16/P afin de commuter au canal 16 (156,8 MHz). (Si le canal 16 n’apparaît pas à l’affichage, appuyez de nouveau sur la touche 16/P jusqu’à ce qu’il soit affiché.) 3. Appuyez sur le bouton Push-to-Talk et dites:“MAYDAY -- MAYDAY -- MAYDAY”. 4. Donnez l’identité de votre navire en disant : “ICI {nom de votre bateau (trois fois) ou indicatif d’appel et le numéro d’identification de votre bateau (une fois)}”. 5. Dites “MAYDAY {nom ou indicatif d’appel de votre bateau} une fois”. 6. Donnez votre position : (quels sont les points de repère ou aides à la navigation près de vous ou lisez les coordonnées de longitude et de latitude apparaissant sur votre dispositif GPS). 7. Révélez la nature de votre détresse (par exemple, nous sommes en train de couler, urgence médicale, un homme à la mer, un incendie, nous sommes à la dérive, etc. 8. Révélez la nature de l’aide désirée (médicale, remorquage, essence, etc.) 9. Donnez le nombre de personnes à bord et les conditions des blessés, s’il y en a. 10. Donnez la condition de navigabilité actuelle de votre navire, tel que le degré de l’urgence par rapport une inondation, et une incendie. 11. Donnez une brève description de votre navire en donnant le nom du bateau (par exemple, “Blue Duck est un yacht de croisière de 32 pieds, avec une coque blanche et un rouffle bleu.). 12. Dites : “JE VAIS ÉCOUTER SUR LE CANAL 16”. 13. Terminez le message en disant “ICI {nom ou indicatif d’appel de votre bateau}, À VOUS”. 14. Relâchez le bouton Push-to-Talk du microphone et écoutez. Si vous n’obtenez pas de réponse après 30 secondes, répétez l’appel en commençant à l’étape 3 ci-dessus. Soulevez le couvercle et appuyez sur le bouton DISTRESS blanc en dessous.
