How Your CobraMarine
VHF Radio Works
This radio is a VHF transceiver for fixed mounting on your boat. 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 and 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 ten 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.

Important Safety Information
Introduction
Recommendations for
Marine Communication
3
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 twenty-five (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 Sideband 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 phones 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.
Important Safety Information
•
Before installing and using your CobraMarine™VHF radio,
please read these general precautions and warnings.
Warning and Caution Statements
To make the most of this radio, it must be installed and used properly.
Please read the installation and operating instructions carefully before
installing 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 radio
or other equipment.
Safety Training Information
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 29 in the
antenna requirements section for further information.
WARNINGS
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 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.

IMPORTANT NOTICE: FCC LICENSING INFORMATION
•
Station License
An 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 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 downloaded
through the internet at www.fcc.gov/forms. Forms can also be obtained by calling
the FCC at 888-225-5322.
International Station License
If 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 Sign
Currently, 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. Illinois 1234 AB) be used as a call sign
and be clearly visible on the vessel.
Canadian Ship Station License
You may need a license if your vessel is operated in Canadian waters. Please contact
the 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 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.

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
you will sound better since your signal will not overpower the nearby station.
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 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 Tal k 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.
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 your calling, hold the microphone on the
front of the radio at least two (2) inches (5 cm) from your mouth and slightly
off to one side. Speak in a normal tone of voice.

Digital Selective Calling
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 VHF Marine Radio Protocols
Maritime Mobile Service Identity (MMSI)
•
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 53 for instructions
on how to enter it.
The MMSI Number Is Available In The U.S.A. From Any Of Three (3) Sources:
■
BoatU.S.: 1-800-563-1536 – www.boatus.com/mmsi

■
Industry Canada, Victoria District Office (only available on the Internet):
http://strategis.ic.gc.ca/SSG/sf01032e.html
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, but under normal conditions should be
approximately 20 nautical miles.

Radiotelephone Calls
•
Boaters may make and receive telephone 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
Although using these services will not damage your radio, 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 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 after
calling on Channel 16) 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.
Marine Emergency Signals
The 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 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.
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.

“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 door and pressing the red button will automatically
send a complete distress call on Channel 70. See the DSC Operation section on
pages 60 to 73 for further information and page 60 instruction on sending a
manual DSC distress call.

NOTE
Many of the plain numbered channels, such as 01, 02, and 03, transmit and
receive on different frequencies. This is termed duplex operation. The rest of
the plain numbered channels and all of the A channels, such as 01A, 03A,
and 04A, transmit and receive on a single frequency, which is termed simplex
operation. Your radio automatically adjusts to these conditions. When in simplex
operation, the A icon will appear on the LCD (see illustration on page A3).
