VHF radio also complies with the
The following WARNINGS and CAUTIONS will make you aware of RF exposure hazards and how to assure you operate the radio within the FCC RF exposure limits established for it.
WARNINGS
Your radio generates electromagnetic RF (radio frequency) energy when it is transmitting. To insure that you and those around you are not exposed to excessive amounts of that energy, DO NOT touch the antenna when transmitting and KEEP yourself and all others on your vessel the required distance away from the antenna while transmitting. SEE page 30 in the antenna requirements section for further information.
DO NOT operate the radio without a proper antenna or equivalent dummy load attached. Doing so may expose you to excessive RF energy and will damage the radio.
DO NOT transmit more than 50% of the time the radio is in use — 50% duty cycle. The radio is transmitting when the Talk button is pressed and the transmit information shows on the LCD screen.
ALWAYS use only Cobra®authorized accessories. DO NOT operate the radio in an explosive atmosphere, near blasting sites,
or in any area where signs are posted prohibiting radio transmissions. NEVER connect the transceiver to AC power. It can be a fire hazard, may
cause an electric shock, and may damage the transceiver. NEVER mount the transceiver or microphone where they might interfere
with operation of your vessel or cause injury. DO NOT allow children or anyone unfamiliar with proper procedures to
operate the radio without supervision. Failure to observe any of these warnings may cause you to exceed
FCC RF exposure limits or create other dangerous conditions.

Introduction
Recommendations For Marine Communication
VHF Marine Radio Protocols
FCC Licensing Information
CAUTIONS AVOID
using or storing the radio at temperatures below -4°F (-20°C) or
above 140°F (60°C). NEVER connect the transceiver to DC power greater than 16 volts or to
any DC source with reversed polarity. Doing so will damage the transceiver. DO NOT cut the power cables attached to the transceiver. Improper
reconnection with reversed polarity will damage the transceiver. POSITION your radio, external speakers, and cables at least three (3) feet (0.9 m)
away from your vessel’s magnetic navigation compass. CHECK your compass before and after installation to be sure that it has not introduced any deviation.
DO NOT attempt to service any internal parts yourself. Have any necessary service performed by a qualified technician.
DO NOT drop the transceiver or microphone. Doing so may crack the case or damage a waterproof seal. Once these items have been dropped, the original waterproofing cannot be guaranteed.
DO NOT use chemicals or solvents such as mineral spirits and alcohol to clean your radio. They may damage the case surfaces.
Changes or modifications to your radio MAY VOID its compliance with FCC 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 vessel navigation and operational messages over a range suitable for nearshore voyages. If the 25 watt maximum output of your radio isn’t sufficient for the distances you travel from the coast, consider installing 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 don’t know where you are, the Coast Guard will have difficulty finding you if you’re 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.

User Responsibility And Operating Locations
All users are responsible for observing domestic and foreign government regulations and are subject to severe penalties for violations. The VHF frequencies on your radio are reserved for marine use and require a special license to operate from land, including when your boat is on its trailer.
NOTE
This device complies with part 15 of the FCC Rules. Operation is subject to the following two (2) conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.
FCC Warnings: Replacement or substitution of transistors, regular diodes, or other parts of a unique nature, with parts other than those recommended by Cobra
®
may cause a violation of the technical regulations of part 80 of the
FCC Rules, or violation 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.
Power
Try 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.
6
English
Limits On Calling
You 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 Channels
After 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 Identification
Identify, in English, your station by your FCC call sign, ship name, the state registration number, or other official number at both the beginning and end of each message.
Prohibited Communications
You 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 particular station) on Channel 16, except in an emergency or if you are testing your radio.
When you are on land.
Voice 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.
NOTE
Channel 9 may be used by recreational vessels for general-purpose calling. This frequency 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 to call. (Hold the microphone a few inches from your face and speak directly into it in a normal tone of voice — clearly and distinctly.) Say “[name of station being called] 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 14 through 15.

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.
NOTE
For best sound quality at the station you’re calling, hold the microphone at least two (2) inches [five (5) cm] from your mouth and slightly off to one (1) side. Speak in a normal tone of voice.
Digital Selective Calling (DSC)
Digital selective calling is a semi-automated system for establishing a radio call. 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 (requires a GPS receiver to be connected to the radio) 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.

VHF Marine Radio Protocols
Emergency Messages And Distress Procedure
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. Calls can be made — for a fee — between your radio and telephones on land, sea, and in the air. See pages 14 through 23 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.
CAUTION
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.
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 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 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. 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.
distress calls, and
Marine Emergency Signals
The three (3) spoken international emergency signals are:
MAYDAY
The distress signal
MAYDAY is used to indicate that a station is threatened
by grave and imminent danger and requests immediate assistance.
AN
P
The urgency signal
PAN is used when the safety of the vessel or person
is in jeopardy. (This signal is properly pronounced pahn.)
SECURITE
The safety signal
SECURITE is used for messages about the safety of navigation or
important 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 Call
You must give any message beginning with one (1) of these signals priority over any other messages. 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.
ALL stations MUST remain silent on Channel 16

VHF Marine Radio Protocols
Emergency Messages and Distress Procedure
Marine Distress Procedure
Speak 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.”
End message by saying:
13.
“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.
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.
or Example
F
“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.
Marine Distress Procedure – DSC
Once your radio is connected to a GPS device and is properly set-up with your MMSI, simply lifting the red spring-loaded door and pressing the button will automatically send a complete distress call on Channel 70. See the DSC operation section on pages 54 through 65 for further information and page 55 instruction on sending a manual DSC distress call.

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 same for all three (3) maps, but there are definite differences (see table on the following pages). Your radio has all three (3) maps built into it and will operate correctly in whichever area you choose.
The following is a brief outline of the channel assignments in the U.S.A. Channel Map.
