Properly used, this Cobra® product will give you  many years of reliable service.How Your CobraMarine VHF Radio WorksThis radio is a battery-powered portable transceiver for use afloat. It gives you  two-way vessel-to-vessel and vessel-to-shore station communications, primarily  for safety and secondarily for navigation and operational purposes. With it, you  can call for help, get information from other boaters, talk to lock or bridge tenders,  and make radiotelephone calls to anywhere in the world through a marine operator.Besides two-way communications, the radio can provide quick access to receive  all the NOAA (National Oceanographic and Atmospheric Administration) weather channels and alert you to weather emergencies with a tone on a weather channel  you can select for your area.Global Positioning Sytem (GPS)Your Cobra Marine radio includes a built-in GPS receiver. Your position will be continuously indicated on the LCD and, most importantly, it will be included automatically with any DSC Distress message you may need to send. That will take the “search” out of “search and rescue”.Customer Assistance  •Should you encounter any problems with this product, or not understand  its many features, please refer to this owner’s manual.

The rst and only boating safety program of its kind, the Sea Tow Automated Radio Check service is fully automated and allows 24 hour a day automated responses to radio check calls.Conducting a radio check through the Sea Tow Automated Radio Check service couldn’t be simpler.  All boaters need to do is tune their VHF radio to Channel 24, 25, 26, 27, 28 or 84 (channel varies by location), then key the mic and ask for a radio check.  The system responds to each radio check with an automated reply including the location, and also replays the boater’s original radio transmission, allowing them to assess the strength of the signal and conrm the VHF radio is in good working order.To nd the Sea Tow Automated Radio Check service channel in an area boaters, radio owners should visit www.seatow.com/arc. The web page allows you to search for the local channel and has an instructional video on how to use the service step by step.FCC Licensing Information  •CobraMarine VHF radios comply with the FCC (Federal Communications Commission) requirements that regulate the Maritime Radio Service.This CobraMarine radio incorporates a VHF FM transceiver designed for use in the frequency range of 156.025 to 163.275 MHz. It has a switchable RF output power of one (1), three (3)  or six (6) watts.The transceiver is capable of Class-D (Digital Selective Calling) operation in accordance with CFR Part 47, Section 80,225. The radio operates on all currently allocated marine channels and is switchable for use according to U.S.A., International or Canadian regulations. It features instant access to emergency Channel 16 and calling Channel 9 as well as NOAA (National Oceanic and Atmospheric Administration) All Hazards Radio with Alert.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 Position Indicating 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 downloaded through the Internet at www.fcc.gov. Forms can also be obtained by calling the FCC at 888-225-5322.International Station LicenseIf your vessel will be entering the sovereign waters of a country other than the U.S.A. or Canada, you should contact that country’s communications regulatory authority for licensing information.Radio Call SignCurrently, the FCC does not require recreational boaters to have a license. The United States Coast Guard recommends that the boat’s registration number and state of registry (e.g., IL 1234 AB) be used as a call sign and be clearly visible on the vessel.4EnglishIntro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceGeneral PrecautionsIntroductionNOTICE  Your 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 qualied technician.This radio is supplied with a lithium-ion (LiON) rechargeable battery pack.n   Use only the Cobra charger to recharge lithium-ion (LiON) batteries in the radio.n   Do not short circuit the battery pack.n      When replacing the batteries, dispose of the old batteries properly. Batteries  may explode if disposed of in a re.CAUTION Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.Changes or modications 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 aoat and for vessel navigation and operational messages over a range suitable for nearshore voyages.  If the 6 watt maximum output of your radio is not sufcient for the distances you travel from the coast, consider installing a Cobra Marine xed mount radio with up to 25 watts of output power. (Visit www.cobra.com or your local dealer for model availability.)If traveling far offshore, you should consider adding even more powerful radio equipment 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 marine radios. 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 hear you. 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 have difculty nding 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 frequencies uncluttered and available for their intended uses.IntroductionIntro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceMRHH600_ENG_MANL.indd   4-5 4/3/17   5:03 PM

NOAA provides continuous, around-the-clock broadcasts 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 Coast Guard also announces weather and other safety warnings on Channel 16. 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 on other bodies of water to be notied, NOAA broadcasts a 1050 Hz tone that receivers such as your CobraMarine VHF radio can detect and warn you of a weather alert condition. When the Weather Alert mode on your radio is set toOn, this signal will produce a loud tone from the speaker in the radio and will automatically switch to the alerting weather channel  so the alert broadcast can be heard.NOAA Test Alert SystemTo test this system, NOAA broadcasts the 1050 Hz signal every Wednesday sometime between 11 a.m. and 1 p.m. in each local time zone. Any receiver that can detect the weather alert tone may use this service to verify that this system is functioning properly.MRHH600_ENG_MANL.indd   30-31 4/3/17   5:03 PM

45Nothing Comes Close to a Cobra®Mobile Phone Operation With Bluetooth®General Bluetooth Operation and Frequently Asked Questionsn   What is the Industry Standard Range for Bluetooth® Wireless Technology?The industry standard range for Bluetooth wireless technology is 30 feet  (10 meters). The radio will loose its pairing with the mobile phone if the  mobile phone and the radio are separated farther than this. The radio will automatically reconnect with the mobile phone when the user comes back into range.n     How many phones can the radio pair with?The radio can be paired with up to 8 mobile phones. However, it can only connect and operate with one mobile phone at a time.n   Do I need to have my mobile phone with me?Yes, the phone call is actually completed through your mobile phone and your mobile phone operator/carrier. The mobile phone must be with the 30 feet  (10 meters) range of the radio. The radio does not increase the offshore  range of your mobile phone.n     Can I use a standard Bluetooth® headset with this radio?No, the radio is using the headset prole of the Bluetooth specication to pair with your mobile phone. It cannot pair to another Bluetooth headset.n     Can I use this unit as a speakerphone or hands-free device?  Turning on VOX allows you to use the radio without pressing the PTT  (Push to Talk) button. The radio will still need to be operated in a face held position with the microphone close to the mouth. This radio uses a noise canceling microphone, and it will not operate well from the belt clip or another hands-free position.VHF Marine Radio ProtocolsIntro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceOperating Your Radio44 EnglishMobile Phone Operation With Bluetooth®VHF Marine Radio ProtocolsIntro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceOperating Your Radion   Please make sure to note your VOX setting.If VOX is set to On, then the receiving caller might hear conversation and noise in your background. This setting is retained in memory. If switched On, then it will  be On the next time the radio is switched On and connected.n   Can I use my mobile phone for emergency use?No, Cobra does not endorse cellular telephones as a substitute for marine radios.  They generally cannot communicate with rescue vessels and, if you make a distress call on your cellular telephone, only the party you call will be able to hear you.  Additionally, cellular telephones may have limited coverage over water. If you do not know where you are, the Coast Guard will have difculty nding you if you  are using your cellular telephone. However, cellular telephones can have a place onboard where cellular coverage is available – to allow social conversations and keep the marine frequencies uncluttered and available for their intended use.MRHH600_ENG_MANL.indd   44-45 4/3/17   5:03 PM

49Nothing Comes Close to a Cobra®VHF Marine Radio ProceduresVHF 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 1 watt rst, 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 output power to increase your calling distance. Remember, the lower wattage outputs 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.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 important function is for Emergency Messages.

It has been designed by the International Maritime Organization (IMO) as an international standard for VHF, MF, and HF calls and is part of the Global Maritime Distress and Safety System (GMDSS). DSC will eventually replace aural (listening) watches on distress frequencies and will be used to announce routine and urgent maritime safety information broadcasts. Until DSC is fully implemented, it is still necessary to maintain a listening watch on Channel 16.The DSC system allows mariners to instantly send a distress call with GPS position coordinates to the Coast Guard and other vessels within range of the transmission. DSC also allows mariners to initiate and receive distress, urgent, safety, routine, position request, position send, and group calls between vessels equipped with DSC capable radios.Maritime Mobile Service Identity (MMSI)   •The MMSI Number Is Available In The U.S.A. From Any Of Two (2) Sources: n  U.S. Power Squadron www.usps.org  n  BoatU.S.– www.getmmsi.comNOTE   The above references are for recreational vessels only. Commercial vessels should contact the FCC.An MMSI is a nine (9) digit number used on a marine radio capable of using digital selective calling (DSC). It is used to selectively call other vessels or shore stations and is similar to a telephone number.For your CobraMarine™ radio to operate in the DSC mode, you must enter your maritime mobile service identity (MMSI) number. See page 55 for instructions  on how to enter it. In Canada, Contact: n    Industry Canada Spectrum Management Ofce (only available on the Internet): www.ic.gc.ca and search for “MMSI”.To Obtain An MMSI Number Outside The U.S.A.:Users can obtain an MMSI from their country’s telecommunications authority  or ship registry. This may involve amending or obtaining a ship station license.WARNING   This equipment is designed to generate a digital maritime distress and  safety signal to facilitate search and rescue. To be effective as a safety  device, this equipment must be used only within communication range  of a shore-based VHF marine channel to distress and safety watch system.  The range of the signal may vary.Intro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceMRHH600_ENG_MANL.indd   52-53 4/3/17   5:03 PM

The result is greater range and more reliable message delivery  per watt of output power.But, that is not the only advantage of DSC equipped radios. Those radios are set up to interface with GPS and to automate many of the operations involved in sending and receiving messages. That results in more compact and accurate messages and less congestion of the airwaves.The price of these benets to the user is the time it takes to do the required set-up to make the DSC features work. A little time spent when your radio is new will pay dividends over its life.User MMSI NumberThe nine (9) digit MMSI number, similar to a telephone number, is a unique identier for a vessel. DSC incorporates this number into every message that is Sent (Tx) or Received (Rx). Enter the MMSI number as soon as you receive your MMSI number from the issuing agency. NOTE  The radio does not operate in the DSC mode until an ofcial MMSI number is entered. An error tone will sound when attempting to operate in the DSC mode without an MMSI number. NOTE  An MMSI number can only be entered one time. To enter a new MMSI number, please contact Cobra customer service. NOTE  An alert tone and message will sound each time you try and use the radio until an MMSI is programmed.To Enter Your MMSI Number:1.  Enter the Settings menu and scroll to DSC SETUP menu  with  the  Up/Down soft keys or the Channel Up/Down   buttons.2.  Press the ENTER soft key and scroll to RADIO MMSI   ENTRY with the Up/Down soft keys or the channel Up/  Down  buttons.3.  Press the ENTER soft key.

Use the Up/Down soft keys or the Channel Up/Down   buttons to scroll through the number list to the rst digit   of your number.5.  Press the ENTER soft key to select the digit and the   blinking cursor will move to the next digit of the number.6.  Repeat steps 3 and 4 until all nine (9) digits of your   MMSI number are entered.7.  Check that you have entered the number correctly. The   radio will ask you to re-enter your number to conrm.8. Press ENTER soft key to save the MMSI number and the   radio will return to the DSC SETUP MENU. NOTE  After the MMSI number has been entered, the RADIO MMSI ENTRY menu option will move to the bottom of the DSC SETUP MENU. This is done because the MMSI entry is entered only once.If You Incorrectly Enter Your MMSI Number YOU CAN DO THIS ONLY ONCE! You will have to contact Cobra® Electronics (see product service on page 66 for details) for reset before you can enter a new MMSI number into the radio.Because the MMSI number is so important to DSC operation, this limitation is imposed on all DSC capable radios to prevent constant changes and the potential introduction of errors in the process.EXIT ENTERDSC SETUP MENURADIO MMSI ENTRYRADIO ATIS ENTRYINDIVIDUAL DIRECTORYGROUP MMSIPOSITION REPLYAUTO CHANNEL SWITCHEMERGDEMO                  PROG     OKATTENTION!DSC IS NOTAVAILABLE.PLEASE ENTERMMSI NUMBEREXIT ENTERRADIO MMSI ENTRYMMSI _ _ _ _ _ _ _ _ _EXIT ENTERRADIO MMSI ENTRYMMSI   123456789EXIT ENTERRADIO MMSI ENTRYRE-ENTER MMSI NUMBERMMSI  _ _ _ _ _ _ _ _ _EXIT ENTERRADIO MMSI ENTRYCONFIRM ENTRYMMSI   123456789EXITRADIO MMSIMMSI   123456789MRHH600_ENG_MANL.indd   54-55 4/3/17   5:03 PM

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 difculties 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 or property and requiring immediate help. Use Channel 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.
