How Your CobraMarine VHF Radio Works
Owner’s Manual

This radio is a VHF transceiver for fixed mounting on your boat. It gives you 2-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 2-way communications, in the U.S.A., the radio can provide quick
access to receive seven NOAA (National Oceanographic and Atmospheric Administration)
and two Canadian weather channels for alerting you to weather emergencies with a tone
on a weather channel you can select for your area.

English

Important Safety Information

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.
NOTE
Throughout this manual, the term “Transceiver” will be used to identify
the main unit containing the LCD screen and controls. The term “Radio”
will be used to identify the entire equipment including transceiver,
microphone, antenna and any attached external speakers.

Introduction

Recommendations For
Marine Communication

VHF Marine Radio Protocols

Sea Tow Automated Radio Check (ARC) System

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 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 (Federal
Communications Commission) rules and make it illegal to use.

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.

Please try the Sea Tow Automated Radio Check service. Areas where the safety check
service is available include the East Coast, Gulf of Mexico, Southern California, and select
inland locations including the Great Lakes. The first 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 confirm the VHF radio is in good working order.
To find 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

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.

Recommendations For Marine Communication

FCC Licensing Information

•

•
CobraMarine VHF radios comply with the FCC (Federal Communication 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 requires 13.8 volts DC and has a
switchable RF output power of one (1) or 25 watts.
The transceiver is capable of Class-D (Digital Selective Calling) operation in accordance
with CFR Part 47, Section 80,225.

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 that can be accessed by pressing one (1) key.

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., IL 1234 AB) be used as a call sign and be clearly visible on the vessel.

You MUST NOT transmit:

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.

Maintain Your Watch

Limits On Calling

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.

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

•

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 1 watt first if the station being called is within a few miles. Try a second call after
waiting two (2) minutes. If there is no answer, switch to a higher power. This will conserve
your battery and minimize interference to other users by avoiding repeated calls.

False distress or emergency messages.

Messages containing obscene, indecent, or profane words or meaning.

eneral calls, signals, or messages (messages not addressed to a particular
G
station) on Channel 16, except in an emergency or if you are testing your radio.

When you are on land.

Voice Calling
n

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.

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.

hen the channel is quiet, press the Talk button and call the ship you wish to
W
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].”

nce contact is made on the calling channel, you must switch to a proper
O
working channel. See the channel listing on page 14 through 15.

Initial Calling on Channel 16 or 9

The use of Channel 16 is permitted for making initial contact (hailing) with another
vessel. The limits on calling must be followed. Be reminded, Channel 16’s most important
function is for Emergency Messages. If, for some reason, Channel 16 is congested, the
use of Channel 9, especially in U.S. waters, may be used as the initial contact (hailing)
channel for non-emergency communication.

To Call Another Vessel Or A Shore Installation Such As A Lock Or Bridge Tender:

Calling Coast Stations

Voice Calling

Nothing Comes Close to a Cobra®

VHF Marine Radio Protocols

Digital Selective Calling (DSC)

Maritime Mobile Service Identity (MMSI)

For Example

The vessel Corsair calling the vessel Vagabond:

The MMSI Number Is Available In The U.S.A. From Any Of Two (2) Sources:
n U.S. Power Squadron www.usps.org

Corsair: “Vagabond, this is Corsair (station license number call sign).”
Vagabond: “Corsair, this is Vagabond. Over.”

Corsair: “Vagabond go to working Channel 68. Over.”
Corsair: “Vagabond I need to talk to you about... Over.”
Vagabond: “Corsair in answer to your question about... Over.”

fter each transmission, say “OVER” and release the microphone Push to Talk (PTT)
A
button. This confirms that the transmission has ended. When all communication
with the other vessel is totally completed, end the message by stating your call sign
and the word “OUT.” Remember, it is not necessary to state your call sign with each
transmission, only at the beginning and end of the message.
NOTE
For best sound quality at the shore station or other vessel receiving your call,
hold the microphone/speaker at least 2 in. (51 mm) from your mouth and
slightly off to one (1) side. Speak in a normal tone of voice.

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.

BoatU.S.: 1-800-563-1536 – www.boatus.com/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.

Corsair: “Vagabond, thanks for the information about... (call sign and out).”

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).

•

NOTE
The above references are for recreational vessels only. Commercial vessels
should contact the FCC.

Both parties switch over to the agreed upon working channel....

Digital Selective Calling (DSC)

VHF Marine Radio Protocols

Maritime Mobile
Service Identity (MMSI)

For your CobraMarine radio to operate in the DSC mode, you must enter your
maritime mobile service identity (MMSI) number. See page 41 for instructions
on how to enter it.
In Canada, Contact:
n Industry Canada Spectrum Management Office (only available on the Internet):
http://strategis.ic.gc.ca/epic/internet/insmt-gst.nsf/vwGeneratedInterE/sf01742e.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.

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

Radiotelephone Calls

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.

VHF Marine Radio Protocols

•

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 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 marine to bring the fuel you need or to give
you a tow.

Emergency Messages
And Distress Procedure

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.
PAN

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. 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.

can find you more quickly if you can transmit a signal for a rescue boat to hone in on.
For Example

2. Select VHF Channel 16.

“Mayday — Mayday — Mayday”

3. Press Talk button and say:
“MAYDAY — MAYDAY — MAYDAY.”
(Or “PAN — PAN — PAN,”
or “SECURITE — SECURITE — SECURITE.”)

“This is Corsair — Corsair — Corsair” [or “Illinois 1234 AB“ three (3) times]

4. Say:
“THIS IS [your vessel name or call sign].” Repeat three (3) times.

“Four adults, three children aboard — no one injured”

5. S
ay:
“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.

“Mayday Corsair (or Illinois 1234 AB)”
“Navy Pier bears 220 degrees magnetic — distance 5 miles”
“Struck submerged object and flooding — need pump and tow”
“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

•

Digital Selective Calling (DSC) is a semi-automated system that will allow you to
press the Distress button from any routine to make a distress call. When the distress
button is pressed, all other channels go to Standby mode and allow the digitally
encoded “pre-programmed” message to take precedence. Important information such
as your MMSI number, position and name will be transmitted on Channel 16. The
distress alarm will sound for two (2) minutes or until the alarm is cleared.
The DSC system allows you to choose a “pre-programmed” distress call such as:
“Man Overboard, Sinking, Collision.” There are many pre-programmed choices
to choose from. If a GPS is connected to your radio, your coordinates will also
be sent to the Coast Guard as well as to other vessels that are within range of
the transmission. DSC calling also allows the user to initiate and receive distress,
urgent, safety, routine, position request, position send and group calls between
vessels equipped with DSC capable radios.
WARNING
This radio will generate a digital maritime distress and safety signal to
help facilitate search and rescue. This radio must be used only within
communication range of a shore based VHF station with a distress and safety
watch system. The range of the signal may vary, however, under normal
conditions should be approximately 20 nautical miles.

Antenna Requirements and Attachment
Antenna Requirements

Installation And Start-Up

•

Your CobraMarine VHF radio requires an external marine antenna
to send signals into the air and to receive them. The radio is arranged
to use any of the popular marine VHF antennas, but it is up to you to
choose which antenna to use.
Since it represents the link between your radio and the outside world,
Cobra suggests you purchase the best quality antenna, coaxial cable
and connectors you can. This is best accomplished with the advice
and guidance of a knowledgeable dealer who can assess the variables
involved with your particular boat and preferences.
WARNING
Compliance with FCC requirements for Radio Frequency Exposure is
the responsibility of both the antenna installer and the radio operator.
Safe Maximum Permissible Exposure (MPE) Radius
To avoid health hazards from excessive exposure to RF energy, FCC OET
Bulletin 65 establishes an MPE radius of 10 ft (3 m) for the maximum power
of your radio with an antenna having a maximum power gain of 9 dBi.
This means that all persons must be at least 10 ft (3 m) away from the
antenna when the radio is transmitting.

Antenna Requirements
And Attachment

WARNING
Do not transmit when anyone is within the MPE radius of the antenna unless
that person or persons are shielded from the antenna by a grounded metallic
barrier. This is especially important on vessels with antennas mounted as
described in B where no one may be within 9 ft (2,8 m) horizontally from the
base of the antenna during transmissions.
FAILURE TO OBSERVE THE ABOVE LIMITS MAY EXPOSE THOSE WITHIN
THE MPE RADIUS TO RF ENERGY ABSORPTION IN EXCESS OF THE FCC
MAXIMUM PERMISSIBLE EXPOSURE. IT IS THE RADIO OPERATOR’S
RESPONSIBILITY TO ENSURE THAT MPE LIMITS ARE HEEDED AND THAT
NO ONE IS WITHIN THE MPE RADIUS DURING TRANSMISSIONS.
Coaxial Cable Socket

Antenna Lead Attachment

Once the antenna is installed, the Coaxial Cable Lead can
be attached to the coaxial cable socket at the back of the
transceiver.
NOTICE
Attempting to transmit without an antenna attached
will damage your CobraMarine VHF radio.

Installation Requirements
n An omnidirectional antenna with a gain not greater than 9 dBi must
be mounted at least 16.4 ft (5 m) above the highest deck where people
may be during radio transmissions, measured vertically from the lowest
point of the antenna. This provides the minimum separation distance
to comply with RF exposure requirements and is based on the MPE
radius of 10 ft (3 m) plus the 6.6 ft (2 m) height of an adult.
n For vessels without structure to mount the antenna as described in A,
it must be mounted as follows AND all persons must be outside the
10 ft (3 m) MPE radius during radio transmissions. The antenna must
be mounted so that its lowest point is at least 3.3 ft (1 m) vertically above
the heads of all persons during radio transmissions.

And Connections

Global Positioning System (GPS) Device (Not Included)

Connect the Microphone to the cord socket located
at the right side of the front of the transceiver.

obra strongly recommends that you obtain and connect a GPS device to
C
your CobraMarine VHF radio. By having a GPS connected, your position will
be continuously indicated on the LCD and, most importantly, it will be included
automatically in any DSC distress message you may need to send. That will
take the “search” out of “search and rescue.”
FCC rules require the radio to prompt the user with visual and audible (beeps) alerts
if a GPS is not connected or position information is not entered manually every four
(4) hours.

GPS Connection

Your CobraMarine VHF radio is set up to connect auxiliary devices for navigation,
convenience, and added versatility. As is the case with the antenna, choosing these
devices is best done with the advice and guidance of a knowledgeable dealer.
Standard connectors are provided on the front and back of the transceiver.
Microphone Socket

External Speaker Jack

Microphone Attachment

To Connect The Microphone Attachment:
1. Align the connector and push it firmly into
the socket.
2. Tighten the captive nut to hold the connector
in place.
3. Slide the waterproof sleeve over the nut until it
seats in the recess around the socket.

22 English

External Speaker (Not Included)

An External Speaker can provide greater volume to
hear messages than the speaker incorporated in the
CobraMarine transceiver.

T o Install An External Speaker:
Connect the speaker lead to the standard jack on the back of
the transceiver.

To Install A GPS Device:
1. Install the GPS device in a convenient location
according to its manufacturer’s directions.
2. Bond the NMEA out negative wire to the black
wire of the GPS interface cable.
3. Bond the NMEA out positive wire to the red
wire of the GPS interface cable.

NOTE
When bonding the wires, make sure connections
are secure and properly insulated.

4. Connect the new combination cable to the GPS
device and to the back of the transceiver.
NOTE
Satellite acquisition time is dependent on the
GPS device.

Digital Selective Calling (DSC) uses digital signals to increase messaging range. This
provides the most reliable message delivery per watt of output power. Digital signals
are less susceptible to distortion from noise and atmospheric conditions than analog
signals.
DSC equipped radios also interface with GPS and automate many operations for
sending and receiving messages. This results in compact, accurate messages and
less airwave congestion.
Setup procedures for all DSC features use the Setup menu. Refer to page 40 for
information on entering and exiting the Setup menu.

User MMSI

number from the issuing agency listed on page 9.
NOTE
The radio does not operate in the DSC mode until an official MMSI number is
entered. An error tone will sound when attempting to operate in the DSC
mode without an MMSI number.

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).
NOTE
All channels are preprogrammed at the factory according to international
regulations and those of the FCC (U.S.A.) and Industry Canada (Canada).
They cannot be altered by the user nor can modes of operation be changed
between simplex and duplex.

Asignación de canales de VHF para radiocomunicación marítima (Español)

NOTA
Muchos de los canales de números simples, como 01, 02 y 03, transmiten
y reciben en diferentes frecuencias. A esto se le llama operación dúplex. El
resto de los canales de números simples y todos los canales A, como 01A,
03A y 04A, transmiten y reciben en una sola frecuencia, a la que se le llama
operación simple (simplex). Su radio se ajusta automáticamente a estas
condiciones. Cuando esté en operación simple, el icono A aparecerá en la
pantalla de cristal líquido (vea la ilustración de la página A3).
