Introduction 5Nothing Comes Close to a Cobra®Radio Check Procedure4English General PrecautionsIntroductionNOTICEYour radio is waterproof only when the batteries are properly installed.AVOID using or storing the radio at temperatures below -4˚F (-20˚C) or above 140˚F (60˚C).KEEP your radio at least 3 ft (0.9 m) away from your vessel’s magnetic navigation compass.DO NOT attempt to service any internal parts yourself. Have any necessary service performed by a qualified technician.This radio is supplied with a lithium-ion (LiON) rechargeable battery pack.■Use only the Cobra charger to recharge lithium-ion (LiON) batteries in the radio.■Do not short circuit the battery pack.■When replacing the batteries, dispose of the old batteries properly. Batteries may explode if disposed of in a fire.Changes or modifications to your radio MAY VOID its compliance with FCC (Federal Communications Commission) rules and make it illegal to use.Recommendations 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. If the 6 watt maximum output of your radio is not sufficient for the distances you travelfrom the coast, consider a higher powered handheld or installing a Cobra Marine fixedmount radio with up to 25 watts of output power. (Visit www.cobra.com or yourlocal dealer for model availability.)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 a distress call on a cellular telephone, only the party you call will be able to hearyou. Additionally, cellular telephones may have limited coverage over water and can be hard to locate. If you do not know where you are, the Coast Guard will havedifficulty finding 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.Introduction Sea Tow Automated Radio Check (ARC) SystemPlease try the Sea Tow Automated Radio Check service. Areas where the safety checkservice is available include the East Coast, Gulf of Mexico, and Southern California,as well as in select inland regions. The first and only boating safety program of itskind, the Sea Tow Automated Radio Check service is fully automated and allows 24hour a day automatic responses to radio check calls.Conducting a radio check through the Sea Tow Automated Radio Check servicecouldn’t be simpler. All boaters need to do is tune their VHF radios to Channel 24, 25,26, 27 or 28, depending on the region, key the mic, and ask for a radio check. TheAutomated Radio Check system responds to each radio check with an automatedreply, and also replays to the boater’s original radio transmission, allowing him or herto assess the strength of the signal and confirm the VHF radio is in good workingorder.To find the Sea Tow Automated Radio Check service channel in an area, ownersshould visit http://www.seatow.com/arc.

7Nothing Comes Close to a Cobra®VHF Marine RadioProcedures6EnglishVHF Marine RadioProcedures Introduction VHF Marine Radio Protocols InstallationVHF 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 6 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 do not 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) another vessel.The limits on calling must be followed. Be reminded, Channel 16’s most importantfunction is for Emergency Messages. If for some reason, Channel 16 is congested,the use of Channel 9, especially in U.S. waters, may be used as the initial contact(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 (if available), vessel name andthe state registration number, at both the beginning and at the end of the message.Prohibited 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.MRHH450DUAL_BODY_MRHH330_ENG_Body 12/5/13 5:57 PM Page 6
Introduction9Nothing Comes Close to a Cobra®Voice Calling8EnglishVoice Calling IntroductionVoice Calling •You are required to listen to Channel 16 while standing by. Channel 16 is the distressand safety channel used for establishing initial contact with another station and foremergency communication. The Coast Guard also monitors Channel 16 for safetypurposes for everyone on the water.NOTEChannel 9 may be used by recreational vessels for general-purpose calling. This frequency should be used whenever possible to help relieve congestion on Channel 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 not in 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. Hold the radio or microphone several inches from your face and speak clearly and distinctly 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 page 60.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 working channel). Over.”Corsair: “Switching to Channel 68. Over.” For Example■If the other does not respond, wait two (2) minutes and repeat. You are permittedto attempt contact three (3) times, two (2) minutes apart. If you still have notmade 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 on the 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.

Introduction11Nothing Comes Close to a Cobra®Emergency Messages andDistress Procedure10 EnglishRadiotelephone Calls Introduction Radiotelephone 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 theAppendix 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.Emergency 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 experience difficultiesand before your situation becomes an emergency. Use the emergency messageprocedures only after your situation has become grave or you are faced with asudden danger threatening life or property and requiring immediate help. UseChannel 16 to communicate your emergency message. Make sure you transmit on high power. If you are merely out of gas, do not send an emergency message.Drop your anchor and call a friend or marina to bring the fuel you need or to give you a tow.MRHH450DUAL_BODY_MRHH330_ENG_Body 12/5/13 5:57 PM Page 10
Introduction13Nothing Comes Close to a Cobra®12 English IntroductionEmergency Messages and Distress ProcedureEmergency Messages andDistress ProcedureMarine 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 in jeopardy. (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 be spokenthree (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 not answered,YOU should answer. If the distressed vessel is not nearby, wait a short time for otherswho may be closer to acknowledge. Even if you cannot render direct assistance, you maybe in a position to relay the message.MAYDAYPANSECURITEMarine 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. Release Talk button and listen. Someone should answer. If not, repeat the call, beginning at step 3 above.Keep the radio nearby. Even after your message has been received, the Coast Guard can find you more quickly if you can transmit a signal for a rescue boat to hone in on.MRHH450DUAL_BODY_MRHH330_ENG_Body 12/5/13 5:57 PM Page 12
Introduction15Nothing Comes Close to a Cobra®Specific Area MessageEncloding (SAME) Alerts14 English IntroductionEmergency Messages andDistress ProcedureFor Example“Mayday — Mayday — Mayday”“This is Corsair — Corsair — Corsair” [or “IL 1234 AB,” repeated three (3) times]“Mayday Corsair (or IL 1234 AB)”“Navy Pier bears 220 degrees magnetic — distance 5 miles”“Struck submerged object and flooding — need pump and tow”“Four (4) adults, three (3) children aboard — no one injured”“Estimate we will remain afloat one-half hour”“Corsair (or IL 1234 AB) is 26 ft sloop with blue hull and tan deck house”“I will be listening on Channel 16”“This is Corsair (or IL 1234 AB)”“Over”It is a good idea to write out a script of the message form and post it where you and others on your vessel can see it when an emergency message needs to be sent.Specific Area Message Encoding (SAME) Alerts •The MR HH450 DUAL radio is capable of receiving Specific Area MessageEncoding (SAME) Alerts. During an NWR weather SAME alert, a code for yourspecific location will alert you to deteriorating weather conditions in apreprogrammed specific area or a specific event such as a Severe ThunderstormWatch or Tropical Storm Warning. There are over 900 National Weather Radio(NWR) service stations using broadcast frequencies that transmit SAME alerts. Youmust program your county, parish or independent city or marine area into the radio.NOTEDO NOT program your radio for a louder or clearer station not designated asa SAME channel. You will not receive the local desired alerts.The NWR service will then alert you only of weather and other emergencies for allareas programmed on this radio.• When an NWR office broadcasts a warning, watch or non-weather emergency,it also broadcasts a digital SAME code that may be heard as a very brief staticburst, depending on the characteristics of the radio. This SAME code containsthe type of message; county(s) affected, and message expiration time.• If programmed correctly, this radio will receive the weather channel so youcan listen to the NWR SAME message. You will hear the 1050 Hz warningalarm tone as an attention signal, followed by the broadcast message.• At the end of the broadcast message, you will hear a brief digital end-ofmessage static burst followed by a resumption of the NWR broadcast cycle. SAME coverage areas are defined within the “NWR Broadcast Service Area” and arecomprised of named counties, boroughs, metropolitan areas or portions thereof. NWR“Broadcast Service Area” coverage by State can be found athttp://www.nws.noaa.gov/nwr or by telephone at 1-888-NWRSAME (1-888-697-7263).The information at the following website,http://www.nws.noaa.gov/nwr/indexnw.htm#sametable, will help to program the SAMEalert county codes and respective frequencies into this radio.
