How Your CobraMarine
™
VHF Radio Works
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 all ten (10) 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
3
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/speaker 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.

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 RTCM SC 101 DSC (Digital Selective Calling) operation.
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 that can be
accessed by pressing one 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., Illinois 1234 AB) be used as a call sign and be clearly visible on the vessel.
Canadian Ship Station License
You need a Radio Operator’s Certificate if your vessel is operated in Canadian waters.
Radio Operator training and certification is available from the Canadian Power
Squadron. Visit their website (http://www.cps-ecp.ca/english/newradiocard.html),
contact the nearest field office or write: Industry of Canada, Radio Regulatory
Branch, Attn: DOSP, 300 Slater Street, Ottawa, Ontario, Canada K1A 0C8.

Recommendations For
Marine Communication
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/speaker. 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.

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/speaker 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.

VHF Marine Radio
Procedures
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.

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 51 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
■
Maritel: 1-888-Maritel (1-888-627-4835)

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.

English
Digital Selective Calling (DSC)
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/speaker
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.

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.

Radiotelephone Calls
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 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.
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.

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 56 through 69 for further information and page 57 instruction
on sending a manual DSC distress call.

VHF Marine Channel Assignments
•
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.
Distress, Safety, And Calling
Channel 16
Getting the attention of another station (calling) or in emergencies
(distress and safety).
Calling
Channel 9
General purpose (non-emergency) calling by non-commercial vessels.
Recreational boaters are urged to use this channel to reduce congestion
on Channel 16.
Intership Safety
Channel 6
Ship-to-ship safety messages and for search and rescue messages to
Coast Guard ships and aircraft.

NOAA Weather Channels
And Alert

NOAA Weather Channels And Alert
•
Monitoring the weather will probably be a frequent use of your radio. The National
Oceanic and Atmospheric Administration (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 and DSC Channel 70. Smart boaters keep an eye on safety and an
ear to the radio — and never let the weather catch them unaware.
NOAA Emergency Weather Alert
In 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 the weather alert alarm tone from the speaker and a “weather
alert” message on the LCD to signal that a weather alert is being broadcast.
The radio will automatically switch to
Weather Radio mode.
Test
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 feature to verify that this feature is functioning properly.

Installation And Start-Up
Radio Operator Requirements
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' (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 INSURE THAT MPE LIMITS ARE HEEDED AND THAT
NO ONE IS WITHIN THE MPE RADIUS DURING TRANSMISSIONS.
Antenna Lead Attachment
Once the antenna is installed, the Coaxial Cable Lead can
be attached to the socket at the back of the transceiver.
CAUTION
Attempting to transmit without an antenna attached
will damage your CobraMarine

Antenna Requirements
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' (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' (3 m) away from the
antenna when the radio is transmitting.
Installation Requirements
A) An omnidirectional antenna with a gain not greater than 9 dBi must
be mounted at least 16.4' (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' (3 m) plus the 6.6' (2 m) height of an adult.
B) 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' (3 m) MPE radius during radio transmissions. The antenna must
be mounted so that its lowest point is at least 3.3' (1 m) vertically above
the heads of all persons during radio transmissions.

Global Positioning System (GPS) Device (Not Included)
Cobra
®
strongly recommends that you obtain and connect a GPS device to
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.”
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 — employs digital RF signals which tend to carry
further and be less susceptible to distortion from noise and atmospheric conditions
than analog ones. 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 benefits 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.
These procedures use the
Settings menu. Refer to page 38 for information on
entering and exiting the
Settings menu.
User MMSI Number
This nine (9) digit number is similar to a telephone number in that it is a unique
identifier for you and your vessel. DSC uses this number in every message it
sends and receives. That is why your radio will not operate in the
DSC mode
until you enter your MMSI Number. You should enter it as soon as you receive
it from one of the issuing agencies listed on page 9.

Group MMSI Number
Nautical organizations such as yacht clubs and the organizers of events
such as regattas can establish Group MMSIs. These allow a message to be
sent automatically to all members of the group without having to call each
one individually.
Each member of the group must enter the group MMSI number in his radio
in order to receive group messages.
To Enter A Group MMSI Number:
1.
Enter the Settings menu and scroll to GRP MMSI
(group MMSI) with the Up/Down buttons.
2. Press the Call/Set button and the blinking cursor will
appear at the first digit under GRP MMSI ID ENTRY.
3. Use the Up/Down buttons to scroll through the
number list to that digit of your number.
4. Press the Call/Set button to select the digit and the
blinking cursor will move to the next digit of the number.
5. Repeat steps 3 and 4 until all nine (9) digits of
the group MMSI number are entered.
NOTE
Press the High/Low Power button to backspace
and erase the last selected number.
6. Check that you have entered the number correctly.
7. Press and hold the Call/Set button to return
to the Settings menu.
The group MMSI is established by modifying the MMSI
assigned to one (1) of the group members. The last digit
of that member’s MMSI number is dropped and a zero (0)
is inserted at the beginning. For example, member MMSI
number 366123456 becomes group MMSI number
036612345.
Group MMSIs can be entered and changed any number
of times without encountering the need to have your
radio reset.

Sending DSC calls is done from menus similar to the Settings menu. Whereas
entering the Settings menu required a press and hold of the Call/Set button,
the sending menus appear with a press of the Distress button.
All received DSC calls will sound one (1) or another of the alarms to alert you to them.
See pages 34 through 35 for descriptions of the different alarms. Pressing any button
will turn Off the alarm while maintaining the received call information on the LCD.
Sending Distress Calls
The ability to send and receive distress calls and their acknowledgements
on Channel 70 can literally be a lifesaver for you or another mariner.
NOTE
The DSC call will:
■
Sound the distress alarm at all receiving stations.
■
Inform receiving stations of your identity (MMSI).
■
Inform receiving stations of your position if you have a GPS
device connected or you have manually entered your position.
It will not provide the receiving stations with other distress information
such as the nature of your problem, number of persons aboard, injuries,
or the like. For that, you will have to communicate by voice on Channel 16
with the station that acknowledges your DSC distress call.
To Begin Sending A DSC Distress Call:
1. From Standby mode, lift the spring-loaded red door on
the transceiver and press the Distress button under it.
This will open the Distress menu with the arrow
pointing to SEND. You will have three (3) choices:
■
Send the distress call automatically with either
no position information if a GPS is not connected
or with the position provided by a connected GPS.
■
Manually enter your position, then send the
distress call.
■
Abort the distress call process and return to
