O r Thanks to Yo •
Thank you for purchasing a CobraMarine®VHF radio.
Properly used, this Cobra®product will give you
many years of reliable service.
How our CobraMarine VHF Radio Works
This radio is a battery-powered portable transceiver for use afloat. 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 or 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 the 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 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 31 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.

Recommendations for
Marine CommunicationImportant Safety Information
Introduction
NOTICE
Your radio is waterproof only when the antenna and batteries are properly
installed.
AVOID using or storing the radio at temperatures below -4˚F (-20˚C) or above
140˚F (60˚C).
KEEP your radio at least 3 ft (0,9 m) away from your vessel’s magnetic navigation
compass.
DO NOT attempt to service any internal parts yourself. Have any necessary
service performed by a qualified technician.
This radio is supplied with an NiMH (Nickel-Metal Hydride) rechargeable battery
pack.
■Use only the Cobra charger to recharge NiMH battery in the radio.
■Do not short circuit the battery pack.
■When replacing the battery, dispose of the old battery properly. The NiMH
battery may explode if disposed of in a fire.
Changes or modifications to your radio MAY VOID its compliance with FCC (Federal
Communications 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 nearshore voyages. If
the 5 watt maximum output of your radio is not sufficient for the distances you
travel from the coast, consider installing a CobraMarine fixed mount radio with up to
25 watts of output power. (Visit www.cobra.com or your local dealer for model
availability.)
If traveling far offshore, you should consider adding even 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 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 on board where cellular coverage
is available — to allow social conversations and keep the marine frequencies
uncluttered and available for their intended uses.

Procedures
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. If there is no answer,
switch to 3 watts and call again. You have the ability to go up to 5 watts of output
power to increase your calling distance. Remember, the lower wattage outputs 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 ther 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) another
vessel. The limits on calling must be followed. Be reminded, Channel 16’s most
important function is for mergency 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.
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 nglish, 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.

■If the other does not respond, wait two (2) minutes and repeat. You are
permitted to attempt contact three (3) times, two (2) minutes apart. If you still
have not made contact, wait 15 minutes before trying again.
■After communications are completed, each vessel must sign off with its call
sign or vessel name and the word “out” and return to Channel 16.
NOTE
For best sound quality at the station you are calling, hold the microphone on
the front of the radio at least 2 in. (51 mm) from your mouth and slightly off to
one (1) side. Speak in a normal tone of voice.
NOTE
“Over and Out”
The most commonly misused procedure words are “over and out” within the
same transmission. “Over” means you expect a reply. “Out” means you are
finished and do not expect a reply.

VHF Marine Radio Protocols
Voice Callin •
You are required to listen to Channel 16 while standing by. Channel 16 is the
distress and safety channel used for establishing initial contact with another station
and for emergency communication. The Coast Guard also monitors Channel 16 for
safety purposes for everyone on the water.
NOTE
Channel 9 may be used by recreational vessels for general-purpose calling. This
frequency should be used whenever possible to help relieve congestion on
Channel 16. The Coast Guard generally does not make urgent marine
information broadcasts or weather warnings on Channel 9. Boaters are still
asked to “keep watch” on Channel 16 whenever the radio is turned on and not
in use with another station.
To call another vessel or shore installation (e.g, lock or bridge tender):
■Make sure the radio is On.
■Make sure you are in standby listening mode on Channel 16. Make sure
Channel 16 is not in use.
■When the channel is open (quiet), press the Talk button and call a vessel. Hold
the radio or microphone several inches from your face and speak clearly and
distinctly in a normal voice tone. Say “name or station being called,” “THIS IS
[your vessel name or call sign].”
■Once contact is made, you must leave Channel 16 and go to another working
channel. See channel listing on pages 20-27.
The vessel Corsair is calling the vessel Vagabond:
Corsair: “Vagabond, this is Corsair. Over.”
Vagabond: “Please switch and answer on Channel 68 (or any proper working
channel). Over.”
Corsair: “Switching to Channel 68. Over.”

IInnttrroodduuccttiioonnRadiotelephone Calls Emergency Messages and
Distress Procedure
Radiotelephone Calls •
Boaters may make and receive radiotelephone calls to and from any number on the
telephone network by using the services of public coast stations. Calls can be made —
for a fee — between your radio and telephones on land, sea and in the air. See pages
20 through 27 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. These 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.
Emer ency Messa es 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:
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-ee-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. ven if you cannot render direct
assistance, you may be in a position to relay the message.

VHF Marine Channel Assi nments •
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.
Coast Guard Liaison

contact on Channel 16.
Non-Commercial
Channels 68*, 69, 71, 72, 78A, 79A*, 80A*
Working channels for small vessels. Messages must be about needs of the
vessel, such as fishing reports, berthing and rendezvous. Use Channel 72 only
for ship-to-ship messages.
Commercial
Channels 1A, 7A, 8, 9, 10, 11, 18A, 19A, 63A, 67, 72, 79A, 80A, 88A*
Working channels for working ships only. Messages must be about business or
needs of the ship. Use Channels 8, 67, 72 and 88A only for ship-to-ship messages.

Messages must be about operational handling, movement and safety of ships.
Navigational
Channels 13, 67
Channels are available to all vessels. Messages must be about navigation, including
passing or meeting other vessels. These are also the main working channels for
most locks and drawbridges. You must keep your messages short and power output
at no more than 1 watt.

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).

N AA Weather Channels
and Alert N AA 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. Smart boaters keep an eye on safety and an
ear to the radio — and never let the weather catch them unaware.
N AA 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 a loud tone from the speaker in the radio and will automatically switch to
the alerting weather channel so the alert broadcast can be heard.
N AA Test Alert System
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 service to verify that this system is functioning properly.

Initial Charge
The Cobra-provided NiMH battery pack may be charged at
home, in a car or in a boat using the appropriate 12V or
120V power cord with the charger.
1. Insert one (1) of the power cords into the back of the
drop-in charger.
2. Insert the other end of the power cord into the
appropriate 12V or 120V power source.
3. Remove the spacer from the charger and insert the entire
radio/battery into the charger. The metal charge contacts
on the battery will contact the mating prongs in the
charger to transfer the charging current.
4. Observe that the red light on the front of the charger
glows to indicate that the battery pack is properly seated
and the charger is operating.
5. Allow the batteries to charge for 12 to 14 hours before
use.
WARNING
Only the rechargeable NiMH battery pack can
be recharged. You MUST use one of the charging
devices provided with this radio. Do not substitute
any other type of charging adapter or charger base
for this radio. Battery damage, fire or explosion may
result. It is equally important to prevent the NiMH
battery pack from freezing to obtain best performance
from the battery pack.
NOTE
If the drop-in charger is used on a boat, Cobra
recommends you attach it to a horizontal shelf or
vertical bulkhead (using the screw holes provided) to
prevent possible damage due to the boat rolling or
pitching. The charging base has been designed to hold
the battery pack in place during rough sea conditions.
