From this mode, you can change current settings by becoming familiar with the different key functions that are active in Marine Standby mode. While in Marine Standby mode, the user will be able to transmit by pressing the Push to Talk (Talk) button. Users will hear signals on the selected channel(s) in Receive (RX) mode and can hear alerts broadcast by the Coast Guard and NOAA. NOTE Coast Guard alerts are broadcast on Channel 16 and you need to have the WX Alert turned On to receive NOAA weather alerts. While in Marine Standby mode, you will receive any messages sent on the channel to which you are tuned.Transmit (Tx) ModeTransmit (Tx) mode gives you the ability to interact with safety services, other vessels and shore stations. When you use this capability, be sure to follow the procedures and to observe the courtesies that govern its use so everyone benefits. See Appendix to help you select the proper channels.To Transmit a Message: 1. Check to see that your radio is set to a proper channel for the type of message you plan to send. 2. Toggle to the Low Power setting for a nearby station. 3. With the microphone about 2 in. [51 mm] from your mouth, press and hold the Talk button and speak into the microphone. The Transmit icon will appear on the LCD. 4. Release the Talk button when you are finished speaking. Your radio can only operate in either Transmit (Tx) or Receive (Rx) mode at any given time. You will not hear the response to your message unless the Talk button is released. If the Battery Power icon begins blinking on the LCD when the Talk button is pressed, the radio will NOT transmit.Low Power ModeCheck Channel NumberTalk ButtonWX Standby DisplayNOAA Weather ChannelsMonitoring the weather will probably be a frequent use of your radio. 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 notified, 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 On, 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 System To 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.These signals will be received in Marine or Weather Standby modes as described below.Weather (WX) Standby ModeTo enter the WX Standby mode, press and hold the Power Level/Weather button. All common operating functions of the radio will work the same in WX Standby mode as they do in the normal Marine Standby mode. The radio will be monitoring for all alerts in the background when in the WX Standby mode when WX Alert is set ON. NOTE If the Talk button is held down for five (5) minutes, the radio will automatically sound a series of beeps and cease transmitting to prevent unwanted signal generation and battery drain. As soon as the Talk button is released, it can be pressed again to resume transmission.Intro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceMRHH125+_MANL_ENG.indd 18-19 4/25/14 4:59 PM](https://usermanual.wiki/Cobra-Electronics/MRHH125B/User-Guide-2277497-Page-12.png)

You are permitted to attempt contact three (3) times, two (2) minutes apart. If you still have not made contact, wait 15 minutes before trying again.n After communications are completed, each vessel must sign off with its call sign or vessel name and the word “out” and return to Channel 16.Intro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceNOTE For 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 to one (1) side. Speak in a normal tone of voice.Intro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceNOTE “Over and Out” The most commonly misused procedure words are “over and out” within the same transmission. “Over” means you expect a reply. “Out” means you are finished and do not expect a reply.For Example30 EnglishVoice CallingVoice Calling •You are required to listen to Channel 16 while standing by. Channel 16 is the distress and safety channel used for establishing initial contact with another station and for emergency communication. The Coast Guard also monitors Channel 16 for safety purposes for everyone on the water.Intro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceNOTE Channel 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 marine information broadcasts or weather warnings on Channel 9. Boaters are still asked 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):n Make sure the radio is On.n Make sure you are in standby listening mode on Channel 16. Make sure Channel 16 is not in use. n 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].”n Once contact is made, you must leave Channel 16 and go to another working channel. See channel listing in the appendix.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.”Radiotelephone Calls •Boaters may make and receive radiotelephone calls to and from any number on the telephone network by using the services of public coast stations. For a fee, calls can be made between your radio and telephones on land, sea and in the air. See the appendix 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.NOTICE You 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.Intro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceMRHH125+_MANL_ENG.indd 30-31 4/25/14 4:59 PM](https://usermanual.wiki/Cobra-Electronics/MRHH125B/User-Guide-2277497-Page-18.png)
![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 PAN is used when the safety of the vessel or person is in jeopardy. (This signal is properly pronounced pahn pahn.)The safety signal SECURITE is used for messages about the safety of navigation or important weather warnings. (This signal is properly pronounced see-cure-ee-tay.)When using an international emergency signal, the appropriate signal is to be spoken three (3) times prior to the message.MAYDAYPAN PANSECURITEIntro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceVHF Marine Radio ProtocolsIntro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceIntro Operation CustomerAssistanceWarrantyNoticeMain IconsSecondary IconsCaution WarningInstallation CustomerAssistanceVHF Marine Radio Protocols33Nothing Comes Close to a Cobra®32 EnglishEmergency Messages and Distress ProcedureEmergency 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, communicate with the Coast Guard 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 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. Drop your anchor and call a friend or marina to bring the fuel you need or to give you a tow.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.Marine 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 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 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.MRHH125+_MANL_ENG.indd 32-33 4/25/14 4:59 PM](https://usermanual.wiki/Cobra-Electronics/MRHH125B/User-Guide-2277497-Page-19.png)
