Introduction5Nothing Comes Close to a Cobra®IntroductionRecommendations for Marine CommunicationRecommendations for Marine Communication •The frequencies your radio uses are set aside to enhance safety afloat and for vesselnavigation and operational messages over a range suitable for nearshore voyages. Ifthe 5 watt maximum output of your radio is not sufficient for the distances youtravel from the coast, consider installing a CobraMarine fixed mount radio with up to25 watts of output power. (Visit www.cobra.com or your local dealer for modelavailability.)If traveling far offshore, you should consider adding even more powerful radioequipment such as HF single side band or satellite radio for your vessel.The U.S. Coast Guard does not endorse cellular telephones as substitutes for marineradios. They generally cannot communicate with rescue vessels and, if you make adistress call on a cellular telephone, only the party you call will be able to hear you.Additionally, cellular telephones may have limited coverage over water and can behard to locate. If you do not know where you are, the Coast Guard will have difficultyfinding you if you are using a cellular telephone.However, cellular telephones can have a place on board where cellular coverage is available — to allow social conversations and keep the marine frequenciesuncluttered and available for their intended uses.MRHH325VP-Body-Eng2:400_Body 10/26/06 12:00 PM Page 5
6EnglishIntroduction FCC Licensing InformationFCC Licensing Information •CobraMarine VHF radios comply with the FCC (Federal CommunicationsCommission) requirements that regulate the Maritime Radio Service.The radio operates on all currently allocated marine channels and is switchable foruse according to U.S.A., International or Canadian regulations. It features instantaccess to emergency Channel 16 and calling Channel 9 as well as NOAA (NationalOceanic and Atmospheric Administration) All Hazards Radio with Alert that can beaccessed by pressing one (1) button.Station LicenseAn FCC ship station license is no longer required for any vessel traveling in U.S.A.waters which uses a VHF marine radio, RADAR, or EPIRB (Emergency PositionIndicating Radio Beacon), and which is not required to carry radio equipment.However, any vessel required to carry a marine radio on an international voyage,carrying an HF single side band radiotelephone, or carrying a marine satellite terminal must obtain a station license.FCC license forms and applications for ship and land stations can be downloadedthrough the Internet at www.fcc.gov. Forms can also be obtained by calling the FCCat 888-225-5322.International Station LicenseIf your vessel will be entering the sovereign waters of a country other than theU.S.A. or Canada, you should contact that country’s communications regulatoryauthority for licensing information.Radio Call SignCurrently, the FCC does not require recreational boaters to have a license. TheUnited States Coast Guard recommends that the boat’s registration number andstate of registry (e.g., IL 1234 AB) be used as a call sign and be clearly visible onthe vessel.Canadian Ship Station LicenseYou need a Radio Operator’s Certificate if your vessel is operated in Canadian waters.Radio Operator training and certification is available from the Canadian PowerSquadron. Visit their website (http://www.cps-ecp.ca/english/newradiocard.html),contact the nearest field office or write: Industry of Canada, Radio RegulatoryBranch, Attn: DOSP, 300 Slater Street, Ottawa, Ontario, Canada K1A 0C8.VHF Marine Radio ProtocolsMRHH325VP-Body-Eng2:400_Body 10/26/06 12:00 PM Page 6

8EnglishIntroductionVHF Marine RadioProceduresVHF Marine Radio Procedures •Maintain Your Watch Whenever your boat is underway, the radio must be turned On and be tuned toChannel 16 except when being used for messages.PowerTry 1 watt first, if the station being called is within a few miles. If there is no answer,switch to 3 watts and call again. You have the ability to go up to 5 watts of outputpower to increase your calling distance. Remember, the lower wattage outputs willconserve your battery and minimize interference to other users.Calling Coast Stations Call a coast station on its assigned channel. You may use Channel 16 when you donot know the assigned channel.Calling Other Vessels Call other vessels on Channel 16 or on Channel 9. (Channel 9 is preferred forrecreational vessel use.) You may also call on ship-to-ship channels when you knowthat the vessel is listening on a ship-to-ship channel.Initial Calling on Channel 16 or 9The use of Channel 16 is permitted for making initial contact (hailing) anothervessel. The limits on calling must be followed. Be reminded, Channel 16’s mostimportant function is for Emergency Messages. If for some reason, Channel 16 iscongested, the use of Channel 9, especially in U.S. waters, may be used as the initialcontact (hailing) channel for non-emergency communication.Limits on CallingYou must not call the same station for more than 30 seconds at a time. If you do not get a reply, wait at least two (2) minutes before calling again. After three (3) calling periods, wait at least 15 minutes before calling again.Change ChannelsAfter contacting another station on a calling channel, change immediately to a channel which is available for the type of message you want to send.Station IdentificationIdentify, in English, your station by your FCC call sign, vessel name and the stateregistration number, at both the beginning and at the end of the message.VHF Marine Radio ProtocolsMRHH325VP-Body-Eng2:400_Body 10/26/06 12:00 PM Page 8
9Nothing Comes Close to a Cobra®VHF Marine RadioProceduresProhibited CommunicationsYou MUST NOT transmit: False distress or emergency messages. Messages containing obscene, indecent or profane language. General calls, signals or messages (messages not addressed to a particularstation) on Channel 16, except in an emergency or if you are testing your radio. When you are on land.VHF Marine Radio ProtocolsMRHH325VP-Body-Eng2:400_Body 10/26/06 12:00 PM Page 9
For Example10 EnglishVoice CallingVHF Marine Radio ProtocolsVoice Calling •You are required to listen to Channel 16 while standing by. Channel 16 is thedistress and safety channel used for establishing initial contact with another stationand for emergency communication. The Coast Guard also monitors Channel 16 forsafety purposes for everyone on the water.NOTEChannel 9 may be used by recreational vessels for general-purpose calling. Thisfrequency should be used whenever possible to help relieve congestion onChannel 16. The Coast Guard generally does not make urgent marineinformation broadcasts or weather warnings on Channel 9. Boaters are stillasked to “keep watch” on Channel 16 whenever the radio is turned on and notin use with another station.To call another vessel or shore installation (e.g, lock or bridge tender):Make sure the radio is On.Make sure you are in standby listening mode on Channel 16. Make sureChannel 16 is not in use. When the channel is open (quiet), press the Talk button and call a vessel. Holdthe radio or microphone several inches from your face and speak clearly anddistinctly in a normal voice tone. Say “name or station being called,” “THIS IS[your vessel name or call sign].”Once contact is made, you must leave Channel 16 and go to another workingchannel. See channel listing on pages 20-27.The vessel Corsair is calling the vessel Vagabond:Corsair: “Vagabond, this is Corsair. Over.”Vagabond: “Please switch and answer on Channel 68 (or any proper workingchannel). Over.”Corsair: “Switching to Channel 68. Over.”MRHH325VP-Body-Eng2:400_Body 10/26/06 12:00 PM Page 10
Introduction11Nothing Comes Close to a Cobra®Voice CallingVHF Marine Radio ProtocolsIf the other does not respond, wait two (2) minutes and repeat. You arepermitted to attempt contact three (3) times, two (2) minutes apart. If you stillhave not made contact, wait 15 minutes before trying again.After communications are completed, each vessel must sign off with its callsign or vessel name and the word “out” and return to Channel 16.NOTEFor best sound quality at the station you are calling, hold the microphone onthe front of the radio at least 2 in. (51 mm) from your mouth and slightly off toone (1) side. Speak in a normal tone of voice.NOTE“Over and Out”The most commonly misused procedure words are “over and out” within thesame transmission. “Over” means you expect a reply. “Out” means you arefinished and do not expect a reply.MRHH325VP-Body-Eng2:400_Body 10/26/06 12:00 PM Page 11
12 EnglishIntroduction Radiotelephone CallsRadiotelephone Calls •Boaters may make and receive radiotelephone calls to and from any number on thetelephone network by using the services of public coast stations. Calls can be made —for a fee — between your radio and telephones on land, sea and in the air. See pages20 through 27 for the public correspondence (marine operator) channels.If you plan to use these services, consider registering with the operator of the public coast station that you plan to work through. These services can provide you with detailed information and procedures to follow.NOTICEYou may disclose privileged information during a radiotelephone call. Keep in mind that your transmission is NOT private, as it is on a regular telephone. Both sides of the conversation are being broadcast and can be heard by anyone who has a radio and tunes to the channel you are using.VHF Marine Radio ProtocolsMRHH325VP-Body-Eng2:400_Body 10/26/06 12:00 PM Page 12
Introduction13Nothing Comes Close to a Cobra®Emergency Messages andDistress ProcedureEmergency Messages and Distress Procedure •The ability to summon assistance in an emergency is the primary reason to have a VHF marine radio. The marine environment can be unforgiving, and what may initially be a minor problem can rapidly develop into a situation beyond your control.The Coast Guard monitors Channel 16, responds to all distress calls, and coordinates all search and rescue efforts. Depending on the availability of other capable vessels or commercial assistance operators in your vicinity, Coast Guard or Coast Guard Auxiliary craft may be dispatched.In any event, communicate with the Coast Guard as soon as you experiencedifficulties and before your situation becomes an emergency. Use the emergencymessage procedures only after your situation has become grave or you are facedwith a sudden danger threatening life or property and requiring immediate help. UseChannel 16 to communicate your emergency message. Make sure you transmit onhigh power. If you are merely out of gas, do not send an emergency message. Dropyour anchor and call a friend or marina to bring the fuel you need or to give you atow.VHF Marine Radio ProtocolsMRHH325VP-Body-Eng2:400_Body 10/26/06 12:00 PM Page 13
14 EnglishIntroductionEmergency Messages and Distress ProcedureVHF Marine Radio ProtocolsMarine Emergency SignalsThe three (3) spoken international emergency signals are:The distress signal MAYDAY is used to indicate that a station is threatened by graveand imminent danger and requests immediate assistance.The urgency signal PAN is used when the safety of the vessel or person is injeopardy. (This signal is properly pronounced pahn.)The safety signal SECURITE is used for messages about the safety of navigation orimportant weather warnings. (This signal is properly pronounced see-cure-ee-tay.)When using an international emergency signal, the appropriate signal is to bespoken three (3) times prior to the message.If You Hear a Distress CallYou must give any message beginning with one (1) of these signals priority over anyother messages. ALL stations MUST remain silent on Channel 16 for the duration ofthe emergency unless the message relates directly to the emergency.If you hear a distress message from a vessel, stand by your radio. If it is notanswered, YOU should answer. If the distressed vessel is not nearby, wait a shorttime for others who may be closer to acknowledge. Even if you cannot render directassistance, you may be in a position to relay the message.MAYDAYPANSECURITEMRHH325VP-Body-Eng2:400_Body 10/26/06 12:00 PM Page 14
Introduction15Nothing Comes Close to a Cobra®Emergency Messages and Distress ProcedureMarine Distress ProcedureSpeak slowly — clearly — calmly.1. Make sure your radio is On.2. Select Channel 16.3. Press Talk button and say: “MAYDAY — MAYDAY — MAYDAY.” (Or “PAN — PAN — PAN,” or “SECURITE — SECURITE — SECURITE.”)4. Say: “THIS IS [your vessel name or call sign],” repeated three (3) times.5. Say: “MAYDAY (or “PAN” or “SECURITE”) [your vessel name or call sign].6. Tell where you are: (what navigational aids or landmarks are nearby).7. State the nature of your distress.8. State the kind of assistance needed.9. Give number of persons aboard and conditions of any injured.10. Estimate present seaworthiness of your vessel.11. Briefly describe your vessel (length, type, color, hull).12. Say: “I WILL BE LISTENING ON CHANNEL 16.”13. End message by saying: “THIS IS [your vessel name or call sign]. OVER.”14.

18 EnglishVHF MarineChannel AssignmentsVHF Marine Channel Assignments •Three (3) sets of VHF channels have been established for marine use in the U.S.A.,Canada and the rest of the world (International). Most of the channels are the samefor all three (3) maps, but there are definite differences (see table on the followingpages). Your radio has all three (3) maps built into it and will operate correctly inwhichever area you choose. The following is a brief outline of the channel assignments in the U.S.A. Channel Map.Distress, Safety, and CallingChannel 16Getting the attention of another station (calling) or in emergencies (distress and safety).Calling Channel 9General-purpose (non-emergency) calling by non-commercial vessels. Recreational boaters are urged to use this channel to reduce congestion on Channel 16.Intership SafetyChannel 6Ship-to-ship safety messages and for search and rescue messages to Coast Guard ships and aircraft.Coast Guard LiaisonChannel 22ATo talk to the Coast Guard, Canadian Coast Guard (non-emergency) after makingcontact on Channel 16.Non-CommercialChannels 68*, 69, 71, 72, 78A, 79A*, 80A*Working channels for small vessels. Messages must be about needs of the vessel, such as fishing reports, berthing and rendezvous.

28 EnglishIntroductionNOAA Weather Channelsand AlertNOAA Weather Channels and Alert •Monitoring the weather will probably be a frequent use of your radio. NOAA providescontinuous, around-the-clock broadcasts of the latest weather information. Tapedweather messages run every four (4) to six (6) minutes and are revised every two(2) or three (3) hours, or as needed. The Coast Guard also announces weather andother safety warnings on Channel 16. Smart boaters keep an eye on safety and anear to the radio — and never let the weather catch them unaware.NOAA Emergency Weather AlertIn the event of a major storm or other weather condition requiring vessels at sea or on other bodies of water to be notified, NOAA broadcasts a 1050 Hz tone thatreceivers such as your CobraMarine VHF radio can detect and warn you of a weatheralert condition. When the Weather Alert mode on your radio is On, this signal willproduce a loud tone from the speaker in the radio and will automatically switch tothe alerting weather channel so the alert broadcast can be heard.VHF Marine Radio ProtocolsMRHH325VP-Body-Eng2:400_Body 10/26/06 12:01 PM Page 28
