many years of reliable service.
How Your 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 ten NOAA (National Oceanographic and Atmospheric Administration) weather
channels and alert you to weather emergencies with a tone on a weather channel
you can select for your area.

Important Safety Information
Introduction 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.
WARNING
Your CobraMarine™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 (beyond FCC allowable
limits for occupational use):
■ ALWAYS hold the radio, especially the antenna, at least two inches (5cm)
away from you when you are transmitting.
■ NEVER allow the antenna to touch any part of your body when transmitting.
■ KEEP the radio and antenna at least as far from bystanders as from yourself.
■ DO NOT operate the radio without the supplied antenna or a Cobra®authorized
replacement attached. In addition to the RF energy exposure hazard, doing so
may 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 icon shows on the LCD screen.
■ ALWAYS use only Cobra®authorized accessories (antennas, batteries,
belt clips, etc.).
■ DO NOT operate the radio where RF energy generated during transmission
may cause electromagnetic interference or incompatibility with other devices
or systems. This includes aircraft, blasting sites, and hospitals.
■ TURN OFF the radio in explosive atmospheres and where signs are posted
prohibiting radio transmissions.
Failure to observe any of these warnings may cause you to exceed
FCC RF exposure limits or create other dangerous conditions.
Important Safety Information •
Before assembling and using your CobraMarine™VHF radio,
please read these general precautions and warnings.
Warning and Caution Statements
To make the most of this radio, it must be assembled and used properly. Please read
the assembly and operating instructions carefully before assembling and using it.
Special attention must be paid to the WARNING and CAUTION statements in this manual.
WARNING

Important Safety Information
Introduction
General Precautions
CAUTION
■ 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 three (3) feet (0.9m) 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.
■Changes or modifications to your radio may void its compliance
with FCC rules and make it illegal to use.
■ This radio is supplied with six (6) NiMH (Nickel-Metal Hydride)
rechargeable batteries.
■ Use only the Cobra®charger to recharge NiMH batteries in the radio.
■ Do not short circuit the battery pack.
■ When replacing the batteries, dispose of the old batteries
properly. NiMH batteries may explode if disposed of in a fire.
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 five (5) watt maximum output of your radio isn’t sufficient for the distances
you travel from the coast, consider installing a CobraMarine™fixed mount radio with up
to twenty-five (25) watts of output power. (Visit www.cobra.com or your local dealer
for model availability.)
If you will be going far offshore, you should consider adding even more powerful
radio equipment such as HF Single Sideband or Satellite Radio for your vessel.
The U.S. Coast Guard does not endorse cellular telephones as substitutes for marine
radios. They generally cannot communicate with rescue vessels and, if you make a
distress call on a cellular telephone, only the party you call will be able to hear you.
Additionally, cellular telephones may have limited coverage over water and can be
hard to locate. If you don’t know where you are, the Coast Guard will have difficulty
finding you if you’re using a cellular telephone.
However, cellular telephones can have a place on board — to allow social
conversations and keep the marine frequencies uncluttered and available for
their intended uses.
IMPORTANT NOTICE: FCC LICENSING INFORMATION •
CobraMarine™VHF radios comply with the FCC (Federal Communication
Commission) requirements that regulate the Maritime Radio Service.
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.

FCC Information VHF Marine Radio Procedures
Radio Call Sign
Currently, the FCC does not require recreational boaters to have a license. The United
States Coast Guard recommends that the boat’s registration number and state of registry
(e.g. Illinois 1234 AB) be used as a call sign and be clearly visible on the vessel.
Canadian Ship Station License
You may need a license if your vessel is operated in sovereign waters of a country
other than the U.S.A. If you are going to operate in Canadian waters, please contact
the nearest field office or write: Industry of Canada, Radio Regulatory Branch,
Attn: DOSP, 300 Slater Street, Ottawa, Ontario, Canada K1A 0C8.
User Responsibility and Operating Locations
All users are responsible for observing domestic and foreign government regulations
and are subject to severe penalties for violations. The VHF frequencies on your radio
are reserved for marine use and require a special license to operate from land,
including when your boat is on its trailer.
NOTE
This device complies with part 15 of the FCC Rules. Operation is subject to the
following two 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.
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 Radiotelephone Calls
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 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 12.
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 are calling, hold the microphone on the
front of the radio at least two (2) inches [five (5) cm] from your mouth and slightly
off to one side. Speak in a normal tone of voice.
VHF Marine Radio Protocols VHF Marine Radio Protocols
For Example
Radiotelephone Calls •
Boaters may make and receive telephone calls to and from any number on the
telephone network by using the services of Public Coast Stations. Calls can be
made — for a fee — between your radio and telephones on land, sea, and in the air.
See pages 12 to 21 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 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, do communicate with the Coast Guard (on Channel 22A) as
soon as you experience difficulties and before your situation becomes an
emergency. Use the emergency message procedures only after your situation
has become grave or you are faced with a sudden danger threatening life or
property and requiring immediate help. If you are merely out of gas, do not
send an emergency message. Drop your anchor and call a friend or marina
to bring the fuel you need or give you a tow.
Marine Emergency Signals
The three (3) spoken international emergency signals are:
The distress signal MAYDAY is used to indicate that a station is threatened
by grave and imminent danger and requests immediate assistance.
The urgency signal PAN is used when the safety of the vessel
or person is in jeopardy. (This signal is properly pronounced pahn.)
The safety signal SECURITE is used for messages about the safety of navigation or
important weather warnings. (This signal is properly pronounced see-cure-it-tay.)
When using an international emergency signal, the appropriate
signal is to be spoken three (3) times prior to the message.
If You Hear A Distress Call
You must give any message beginning with one (1) of these signals
priority over any other messages. ALL stations MUST remain silent on
Channel 16 for the duration of the emergency unless the message relates
directly to the emergency.
If you hear a distress message from a vessel, stand by your radio.
If it is not answered, YOU should answer. If the distressed vessel is
not nearby, wait a short time for others who may be closer to acknowledge.
Even if you cannot render direct assistance, you may be in a position to
relay the message.

Emergency Messages
and Distress Procedure
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.
“Mayday — Mayday — Mayday”
“This is Corsair — Corsair — Corsair” (or “Illinois 1234 AB” three (3) times)
“Mayday Corsair (or Illinois 1234 AB)”
“Navy Pier bears 220 degrees magnetic — distance five (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 (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.

NOAA Weather Channels Included in This Package
NOAA Weather Channels •
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 then
broadcasts the warning on Channel 22A. 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
a loud tone from the speaker in the radio and a flashing “ALRT” icon on the LCD to
signal that a weather alert is being broadcast. To hear the warning itself, you will need
to switch to the Weather Channel you selected.
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.

Batteries and Charger Batteries and Charger
1. Insert one of the power cords into the back of the
drop-in charging cradle.
2. Insert the other end of the power cord into the
appropriate 12 or 120 volt power source.
3. Insert the radio into the charger. The metal pads
on the radio will contact mating pads in the charger
to transfer the charging current.

glows to indicate that the radio is properly seated and
the charger is operating.
5. Allow the batteries to charge for 12 to 15 hours.
NOTE
If the drop-in charger is to be used on a boat,
Cobra® recommends you attach it to a shelf or
bulkhead (using the screw holes provided) to
prevent damage due to the boat rolling or pitching.
Maintaining the Battery Charge
As you use your radio, the battery power icon will
show the battery power remaining. When the icon
shows only one or no segment, it is time to recharge
or change the batteries.
You can monitor incoming calls while the radio is
charging. However, you should remove it from the
charger to transmit. Charging will be quicker if the
radio is turned Off.
CAUTION
Use only the drop-in charger provided by Cobra®.
Do not use the charger with alkaline batteries; only
the NiMH batteries are rechargeable. Spent alkaline
batteries must be discarded and replaced.
It is a good idea to keep a set of fresh, high quality
alkaline batteries with your radio. Should the rechargeable
batteries become discharged and no electrical power
source be available, you can insert the alkaline batteries
and continue to use your radio until you can return to
using the rechargeable ones.
Installation Installation

U.S.A./International/Canada Channel Maps
Three (3) sets of VHF channel maps 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 maps, but there are definite differences (see table on
pages 12 through 21). Your radio has all three (3) maps built into it and will
operate correctly in whichever area you choose.
To Set Your Radio For The Area
In Which You Will Be Using It:
1. From Standby mode, press and hold the Weather/UIC
button for two (2) seconds. The radio will shift one
channel map and the Active Channel Map icon on
the LCD will show the change on the LCD.
2. Repeat step 1 to shift to the next channel map(s).
Channels
Your radio will receive and transmit VHF signals
on the channel indicated on the LCD. You can change
the channel at any time using the Channel Up and
Channel Down buttons.
To Change Channels:
1. Press the Channel Up or Channel Down button.

You can hold the Channel Up or Channel Down
button for fast advance.
The beep sound will occur only at the first press
of the button and not during fast advance.
If the new channel selected is restricted to low power,
the radio will automatically switch to Low Power mode
and the Low Power icon will appear on the LCD.
If the radio is in the Key Lock mode, the channel will not
change and the three (3) beep error signal will sound.
Transmit Power Output
Your radio can transmit selectively at one (1) or
five (5) watts of power. Cobra®suggests you maintain
the low power setting for short-range communications,
to conserve battery life, and to avoid overpowering
nearby stations with your signal. Use the high power
setting for long-range communications or when you do
not receive a response to a signal sent at one (1) watt.
To Toggle Between The High And Low Power Modes:
1. Press the High/Low Power button.
The LCD will show which mode is in effect.
Some channels are restricted to use at a maximum
of one (1) watt. Your radio will automatically set
the power to Low Power mode when you select
those channels.
Backlight
The LCD will be illuminated by the backlight as long
as any key is pressed and will remain on for five (5)
seconds after the button is released.
If You Need To Turn On The Backlight
Without Disturbing Any Settings:
1. Press the Backlight/Key Lock button. The
backlight will remain On for five (5) seconds.
If the backlight is On, a press of the Backlight/
Key Lock button will turn it Off.

Standby/Receive and Transmit •
Standby and Receive
Standby is the usual mode for the radio whenever it is turned On. From this
mode, you can change your settings using the buttons on the front of the radio
and switch to Transmit mode using the Talk button. Signals will be received on
the selected channel(s) and alerts broadcast by the Coast Guard and NOAA will
activate the corresponding routines in your radio.
NOTE
Coast Guard alerts are broadcast on Channel 16 and you
need to have Weather Alert turned On to receive NOAA alerts.
While in Standby mode, you will Receive any messages sent on the channel
to which you are tuned.
Transmit
Transmit mode gives you the ability to interact with safety
services, other vessels, and shore stations. When you use
this capability, be sure to follow the procedures and to
observe the courtesies that govern its use so everyone
benefits. (The tables on pages 12 through 21 will help
you select the proper channels.)
To Transmit A Message:
1. Check to see that your radio is set to a proper
channel for the type of message you plan to send.
2. Toggle to the Low Power setting.
3. With the microphone about two (2) inches (5 cm)
from your mouth press and hold the Talk button
and speak into the microphone. The Transmit icon
will appear on the LCD.
4. Release the Talk button when you are finished
speaking. Your radio can only operate in either the
Transmit or the Receive mode at any given time.
You will not hear the response to your message
unless the Talk button is released.
If the Battery Power icon drops to the blinking
1-segment level on the LCD when the Talk button
is depressed, the radio will NOT transmit and the
Transmit icon will blink.
If the Talk button is held down for five (5) minutes,
the radio will automatically cease transmitting to prevent
unwanted signal generation and battery drain. As soon
as the Talk button is released, it can be pressed again
to resume transmission.
