Introduction3Nothing comes close to a Cobra®2EnglishImportant Safety InformationIntroduction Important Safety InformationThe following WARNINGS and CAUTIONS will make you aware of RF exposurehazards and how to assure you operate the radio within the FCC RF exposure limits established for it.WARNINGYour CobraMarine™radio generates electromagnetic RF (radio frequency) energy when it is transmitting. To ensure that you and those around you are not exposed to excessive amounts of that energy (beyond FCC allowable limits for occupational use):■ ALWAYS hold the radio, especially the antenna, at least two inches (5cm) away from you when you are transmitting.■ NEVER allow the antenna to touch any part of your body when transmitting.■ KEEP the radio and antenna at least as far from bystanders as from yourself.■ DO NOT operate the radio without the supplied antenna or a Cobra®authorizedreplacement attached. In addition to the RF energy exposure hazard, doing so may damage the radio.■ DO NOT transmit more than 50% of the time the radio is in use — 50% dutycycle. The radio is transmitting when the Talk button is pressed and the Transmit icon shows on the LCD screen.■ ALWAYS use only Cobra®authorized accessories (antennas, batteries, belt clips, etc.).■ DO NOT operate the radio where RF energy generated during transmission may cause electromagnetic interference or incompatibility with other devices or systems. This includes aircraft, blasting sites, and hospitals.■ TURN OFF the radio in explosive atmospheres and where signs are postedprohibiting radio transmissions.Failure to observe any of these warnings may cause you to exceed FCC RF exposure limits or create other dangerous conditions.Important Safety Information •Before assembling and using your CobraMarine™VHF radio, please read these general precautions and warnings.Warning and Caution StatementsTo make the most of this radio, it must be assembled and used properly. Please readthe assembly and operating instructions carefully before assembling and using it.Special attention must be paid to the WARNING and CAUTION statements in this manual.WARNING Statements identify conditions that could result in personal injury or loss of life.CAUTION Statements identify conditions that could cause damage to the radioor other equipment.Safety Training InformationThis CobraMarine™radio is designed for and classified as “Occupational Use Only.” It must only be used in the course of employment by individuals aware of both thehazards and the ways to minimize those hazards. This radio is NOT intended for use in an uncontrolled environment by the “General Population.”This radio has been tested and complies with the FCC RF exposure limits for“Occupational Use Only.” This CobraMarine™VHF radio also complies with thefollowing guidelines and standards regarding RF energy and electromagnetic energy levels as well as evaluation of those levels for human exposure:■ FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.■ American National Standards Institute (C95.1-1992), IEEE Standard for SafetyLevels with Respect to Human Exposure to Radio Frequency ElectromagneticFields, 3kHz to 300 GHz.■ American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields —RF and Microwave.
Introduction5Nothing comes close to a Cobra®Recommendations for Marine Communication4EnglishImportant Safety InformationIntroductionGeneral PrecautionsCAUTION ■ Your radio is waterproof only when the antenna and 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 three (3) feet (0.9m) 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.■Changes or modifications to your radio may void its compliance with FCC rules and make it illegal to use.■ This radio is supplied with six (6) NiMH (Nickel-Metal Hydride) rechargeable batteries.■ Use only the Cobra®charger to recharge NiMH batteries in the radio.■ Do not short circuit the battery pack.■ When replacing the batteries, dispose of the old batteries properly. NiMH batteries may explode if disposed of in a fire.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 five (5) watt maximum output of your radio isn’t sufficient for the distances you travel from the coast, consider installing a CobraMarine™fixed mount radio with upto twenty-five (25) watts of output power. (Visit www.cobra.com or your local dealer for model availability.)If you will be going far offshore, you should consider adding even more powerfulradio equipment such as HF Single Sideband 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 don’t know where you are, the Coast Guard will have difficultyfinding you if you’re using a cellular telephone.However, cellular telephones can have a place on board — to allow socialconversations and keep the marine frequencies uncluttered and available for their intended uses.IMPORTANT NOTICE: FCC LICENSING INFORMATION •CobraMarine™VHF radios comply with the FCC (Federal CommunicationCommission) requirements that regulate the Maritime Radio Service.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 a 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. Forms can also be obtained by callingthe FCC at 888-225-5322.VHF Marine Radio Protocols
7Nothing comes close to a Cobra®6EnglishFCC Information VHF Marine RadioProceduresRadio Call SignCurrently, the FCC does not require recreational boaters to have a license. The UnitedStates Coast Guard recommends that the boat’s registration number and state of registry(e.g. Illinois 1234 AB) be used as a call sign and be clearly visible on the vessel.Canadian Ship Station LicenseYou may need a license if your vessel is operated in sovereign waters of a countryother than the U.S.A. If you are going to operate in Canadian waters, please contactthe nearest field office or write: Industry of Canada, Radio Regulatory Branch, Attn: DOSP, 300 Slater Street, Ottawa, Ontario, Canada K1A 0C8.User Responsibility and Operating LocationsAll users are responsible for observing domestic and foreign government regulationsand are subject to severe penalties for violations. The VHF frequencies on your radioare reserved for marine use and require a special license to operate from land,including when your boat is on its trailer.NOTEThis device complies with part 15 of the FCC Rules. Operation is subject to thefollowing two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interferencethat may cause undesired operation.FCC Warnings: Replacement or substitution of transistors, regular diodes, or otherparts of a unique nature, with parts other than those recommended by Cobra®maycause a violation of the technical regulations of part 80 of the FCC Rules, orviolation of type acceptance requirements of part 2 of the Rules.VHF Marine Radio Procedures •Maintain Your Watch Whenever your boat is underway, the radio must be turned On and be tuned to Channel 16 except when being used for messages.PowerTry one (1) watt first if the station being called is within a few miles. If there is no answer, switch to a higher power. This will conserve 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 for recreational vessel use.) You may also call on ship-to-ship channels when you know that the vessel is listening on a ship-to-ship channel.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, ship name, the state registrationnumber, or other official number at both the beginning and end of each message.Prohibited CommunicationsYou MUST NOT transmit:■ False distress or emergency messages.■ Messages containing obscene, indecent, or profane words or meaning.■ 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 ProtocolsVHF Marine Radio Protocols
9Nothing comes close to a Cobra®8EnglishVoice Calling Radiotelephone CallsVoice Calling •To Call Another Vessel Or A Shore Installation Such As A Lock Or Bridge Tender:■ Make sure your radio is On.■ Select Channel 16 and listen to make sure it is not being used. NOTEChannel 9 may be used by recreational vessels for general-purpose calling. Thisfrequency should be used whenever possible to relieve congestion on Channel 16.■ When the channel is quiet, press the Talk button and call the ship you wish tocall. (Hold the microphone a few inches from your face and speak directly into itin a normal tone of voice — clearly and distinctly.) Say “[name of station beingcalled] THIS IS [your vessel’s name or call sign].”■ Once contact is made on the calling channel, you must switch to a proper working channel. See the channel listing on page 12.The vessel Corsair calling the vessel Vagabond:Corsair: “Vagabond, this is Corsair.”Vagabond: “Corsair, this is Vagabond. Reply 72 (or any proper working channel).”Corsair: “72” or “Roger”■ After communications are completed, each vessel must sign off with its call sign or vessel name and switch to Channel 16.NOTEFor best sound quality at the station you are calling, hold the microphone on thefront of the radio at least two (2) inches [five (5) cm] from your mouth and slightlyoff to one side. Speak in a normal tone of voice.VHF Marine Radio Protocols VHF Marine Radio ProtocolsFor ExampleRadiotelephone Calls •Boaters may make and receive telephone 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 pages 12 to 21 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. Those services can provide you with detailed information and procedures to follow.CAUTIONYou may disclose privileged information during a radiotelephone call. Keep in mindthat your transmission is NOT private, as it is on a regular telephone. Both sides ofthe conversation are being broadcast and can be heard by anyone who has a radio and tunes to the channel you are using.
11Nothing comes close to a Cobra®10 EnglishEmergency Messages and Distress Procedure Emergency Messages and Distress 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, do communicate with the Coast Guard (on Channel 22A) as soon as you experience difficulties and before your situation becomes an emergency. Use the emergency message procedures only after your situation has become grave or you are faced with a sudden danger threatening life orproperty and requiring immediate help. 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 give you a tow.Marine Emergency SignalsThe three (3) spoken international emergency signals are:The distress signal MAYDAY is used to indicate that a station is threatened by grave and 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-it-tay.)When using an international emergency signal, the appropriate signal is to be spoken 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 any other messages. ALL stations MUST remain silent on Channel 16 for the duration of the 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 others who may be closer to acknowledge.Even if you cannot render direct assistance, you may be in a position to relay the message.VHF Marine Radio Protocols VHF Marine Radio ProtocolsMAYDAYPANSECURITE
For Example13Nothing comes close to a Cobra®Emergency Messages and Distress Procedure12 EnglishEmergency Messages and Distress ProcedureKeep the radio nearby. Even after your message has been received, the Coast Guardcan find you more quickly if you can transmit a signal for a rescue boat to hone in on.“Mayday — Mayday — Mayday”“This is Corsair — Corsair — Corsair” (or “Illinois 1234 AB” three (3) times)“Mayday Corsair (or Illinois 1234 AB)”“Navy Pier bears 220 degrees magnetic — distance five (5) miles”“Struck submerged object and flooding — need pump and tow”“Four adults, three children aboard — no one injured”“Estimate we will remain afloat one half (1⁄2) hour”“Corsair (or Illinois 1234 AB) is 26 foot sloop with blue hull and tan deck house”“I will be listening on Channel 16”“This is Corsair (or Illinois 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.VHF Marine Radio Protocols VHF Marine Radio ProtocolsMarine Distress ProcedureSpeak slowly — clearly — calmly.1. Make sure your radio is On.2. Select VHF 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].”5. Say: “MAYDAY (or “PAN” or “SECURITE”) [your vessel name or call sign].6. Tell where you are: (what navigational aids or landmarks are near).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 item 3 above.

25Nothing comes close to a Cobra®24 EnglishNOAA Weather Channels Included in This PackageNOAA Weather Channels •Monitoring the weather will probably be a frequent use of your radio. The NationalOceanic and Atmospheric Administration (NOAA) provides continuous, around-the-clockbroadcasts of the latest weather information. Taped weather messages run every four (4)to six (6) minutes and are revised every two (2) or three (3) hours, or as needed. The CoastGuard also announces weather and other safety warnings on Channel 16, and thenbroadcasts the warning on Channel 22A. Smart boaters keep an eye on safety and an ear 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 onother bodies of water to be notified, NOAA broadcasts a 1050 Hz tone that receiverssuch as your CobraMarine™VHF radio can detect and warn you of a Weather AlertCondition. When the Weather Alert mode on your radio is On, this signal will producea loud tone from the speaker in the radio and a flashing “ALRT” icon on the LCD tosignal that a weather alert is being broadcast. To hear the warning itself, you will needto switch to the Weather Channel you selected.TestTo test this system, NOAA broadcasts the 1050 Hz signal every Wednesday sometimebetween 11 a.m. and 1 p.m. in each local time zone. Any receiver that can detect theweather alert tone may use this feature to verify that this feature is functioning properly.Weather FrequencyChannel RX Frequency MHz1 162.5502 162.4003 162.4754 162.4255 162.4506 162.5007 162.5258 161.6509 161.77510 163.275Included in This Package •You should find all of the following items in the package with your CobraMarine™VHF radio:Radio With Wrist Strap Drop-In Battery Charger Flexible AntennaBattery Charger Power CordFor connection to 120 volt wall outlet.Battery TrayWith 6 AA NiMH batteries.Battery Charger Power CordFor connection to 12 voltsource through cigarettelighter.Operating Instruction Manual Belt ClipVHF Marine Radio Protocols Installation
