Introduction
Owner’s Manual
Our Thanks to you and
Customer Assistance
Thank you for purchasing a CobraMarine® VHF radio.
Properly used, this Cobra® product will give you
many years of reliable service.
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 NOAA (National Oceanographic and Atmospheric
Administration), including two Canadian weather channels for alerting you to
weather emergencies with a tone on a weather channel you can select for your area.

Important Safety Information
The following WARNINGS and NOTICE information will make you aware of RF
exposure hazards and how to assure you operate the radio within the FCC RF
exposure limits established for the radio.
WARNINGS
Your radio generates electromagnetic RF (radio frequency) energy when
it is transmitting. To ensure 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.
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.

Recommendations for
Marine Communication
NOTICE
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 3 ft (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 (Federal
Communication Commission) 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 near-shore
voyages. If the 25 watt maximum output of your radio is not sufficient for the
distances you travel from the coast, consider installing a more powerful radio 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 do not know where you are, the
Coast Guard will have difficulty finding you if you are using a cellular telephone.
However, cellular telephones can have a place onboard where cellular coverage
is available — to allow social conversations and keep the marine frequencies
uncluttered and available for their intended use.

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 radio is capable of Class-D 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/formpage.html. 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.
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.

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 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.
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.
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.

Voice Calling
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, vessel name and the state
registration number, at both the beginning and at the end of the message.
Prohibited Communications
You MUST NOT transmit:
■
False distress or emergency messages.
■
Messages containing obscene, indecent or profane language.
■
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 Shore Installation (e.g. 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 vessel 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.

Digital Selective Calling (DSC)
For Example
The vessel Corsair calling the vessel Vagabond:
Corsair: “Vagabond, this is Corsair (station license number call sign).”
Vagabond: “Corsair, this is Vagabond. Over.”
Corsair: “Vagabond go to working Channel 68. Over.”
Both parties switch over to the agreed upon working channel....
Corsair: “Vagabond I need to talk to you about... Over.”
Vagabond: “Corsair in answer to your question about... Over.”
Corsair: “Vagabond, thanks for the information about... (call sign and out).”
After each transmission, say “OVER” and release the microphone Push to Talk (PTT)
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.
Digital Selective Calling (DSC)
Digital selective calling (DSC) 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.

Service Identity (MMSI)
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 62 for instructions
on how to enter your number.
MMSI Numbers are available in the U.S.A. from these Sources:
■ Boat U.S.: 800-563-1536 – www.boatus.com/mmsi
■
Maritel: 888-Maritel (888-627-4835)
■
Sea Tow International: 631-765-3660 – www.seatow.com
In Canada, Contact:
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.

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.
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.

Emergency Messages
and Distress Procedure
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, 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.
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-ee-tay.)
When using an international emergency signal, the appropriate
signal is to be spoken three (3) times prior to the message.

Emergency Messages
and Distress Procedure
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.
Marine Distress Procedure
Speak 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,”
or “SECURITE — SECURITE — SECURITE.”)
4. Say:
“THIS IS [your vessel name or call sign],” repeated three (3) times.
5. Say:
“MAYDAY (or “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.

Emergency Messages
and Distress Procedure
For Example
“Mayday — Mayday — Mayday”
“This is Corsair — Corsair — Corsair” [or “IL 1234 AB”], repeated three (3) times.
“Mayday Corsair (or IL 1234 AB)”
“Navy Pier bears 220 degrees magnetic — distance 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 hour”
“Corsair (or IL 1234 AB) is 26 ft sloop with blue hull and tan deck house”
“I will be listening on Channel 16”
“This is Corsair (or IL 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.

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 pages 16-23).
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.

Many of the plain numbered channels, such as 01, 02 and 03, transmit on one
frequency and receive on another. 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 A2).

NOAA Weather Channels
and Alert
NOAA Weather Channels and Alert
•
Monitoring 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 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.

Antenna Requirements
and Attachment
Antenna Requirements and Attachment
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 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.
Installation Requirements
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.
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.

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.

Global Positioning System (GPS) Device
(Not Included)
NMEA/IO Cable
Cobra Electronics 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 of your GPS to the
NMEA in negative (-) wire (green) of the MR F80
NMEA/IO interface cable.
3. Bond the NMEA out positive (+) wire of your GPS to the
NMEA in positive (+) wire (white) of the MR F80
NMEA/IO interface cable.
NOTE
When bonding the wires, make sure connections are
secure and properly insulated to prevent electrical
arching.
4. Connect the new combination cable to the GPS device
and to the back of the transceiver.
