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 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
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. KEEP the
radio at least two (2) inches (5cm) away from yourself and others when transmitting.
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 place 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.
NOTICE
Your radio is waterproof only when the 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 NiMH (Nickel-Metal Hydride) rechargeable batteries.
■
Use only the Cobra power cord to recharge NiMH batteries in the radio.
■
Do not short circuit the batteries.
■
When replacing the batteries, dispose of the old batteries properly. The NiMH
batteries 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.

Marine Communication,
Procedures & FCC Licensing
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 3 watt maximum output of your radio is not sufficient for the distances you travel
from the coast, consider a higher powered handheld or installing a Cobra Marine 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.
VHF Marine Radio Procedures
If you are not familiar with or need to brush up on the protocols that must be
followed when using a VHF Marine Radio, please study the section beginning
at page 28 before putting your radio into service.
FCC Licensing Information
CobraMarine VHF radios comply with the FCC (Federal Communications
Commission) requirements that regulate the Maritime Radio Service.
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 (1) button.

•
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 an HF single side
band radiotelephone, or carrying a marine satellite terminal must obtain a station license.

FCC Licensing
FCC license forms and applications for ship and land stations can be downloaded
through the Internet at www.fcc.gov. 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.
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 Warning: 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.

HI/LO Power Button
High/Low (HI/LO) Power Button
Your radio can transmit selectively at 1 or 3 watts of power.
Cobra suggests you maintain the low power setting for
short-range communication. You will conserve battery life
and avoid overpowering nearby stations by using a low
power signal. Use the High Power setting for long-range
communications or when you do not receive a response
to a signal sent at 1 watt.
To Toggle Between HI/LO Power Modes:
Press the Power Level/Weather button. The LCD
will show which mode is in effect. Some channels are
restricted for a maximum use of 1 watt. Your radio will
automatically set the power to Low Power mode when
you select those channels.
NOTE
Some channels, frequency bands and countries of use
might not be able to operate in High Power mode.

Marine Standby and Receive (Rx) Mode
•
Marine Standby mode is the default mode for the radio whenever it is turned On.
From this mode, you can change current settings by becoming familiar with the
different key functions that are active in Marine Standby mode. While in Marine
Standby mode, the user will be able to transmit by pressing the Push to Talk (Talk)
button. Users will hear signals on the selected channel(s) in Receive (RX) mode and
can hear alerts broadcast by the Coast Guard and NOAA.
NOTE
Coast Guard alerts are broadcast on Channel 16 and you need to have the WX
Alert turned On to receive NOAA weather alerts. While in Marine Standby mode,
you will receive any messages sent on the channel to which you are tuned.
Transmit (Tx) Mode
Transmit (Tx) 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. See Appendix to help
you select the proper channels.
To Transmit a Message:
Check Channel Number
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 2 in. [51 mm] from your
mouth, press and hold the Talk button and speak into the
microphone. The Transmit icon will appear on the LCD.
Low Power Mode
4. Release the Talk button when you are finished
speaking. Your radio can only operate in either
Transmit (Tx) or Receive (Rx) 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 begins blinking on the
Talk Button
LCD when the Talk button is pressed, the radio
will NOT transmit.
18 English
NOTE
If the Talk button is held down for five (5) minutes,
the radio will automatically sound a series of beeps
and 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.

NOAA All Hazards/Weather
Radio and Alert
NOAA Weather Channels
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.
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 will automatically switch to
the alerting weather channel so the alert broadcast can be heard.
NOAA 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.
These signals will be received in Marine or Weather Standby modes as described below.
WX Standby Display
Weather (WX) Standby Mode
To enter the WX Standby mode, press and hold the
Power Level/Weather button. All common operating
functions of the radio will work the same in WX Standby
mode as they do in the normal Marine Standby mode. The
radio will be monitoring for all alerts in the background when
in the WX Standby mode.

WX Alert Standby Mode
When NOAA broadcasts a weather alert signal and your radio is in WX Alert Standby
mode, the following items will be displayed on the LCD display:
■ The WX icon (cloud/sun) icon will be displayed.
■ The last used weather channel will be displayed.
■ The bar graph will display received signal strength level.
■ The WX Alert icon (safety triangle) will be displayed.
NOTE
Only one (1) or two (2) of the weather channels will be operating in any
given location (only in Receive (Rx) mode). You will need to select the
channel with the strongest signal in your location.
NOTE
When in the WX Alert mode, and NOAA sends the 1050Hz alert tone,
the radio will sound a series of loud beeps regardless of the volume
control setting.
WX Auto Search (SCAN)
WX Auto Search (SCAN) Mode Function:
The purpose of the WX Auto Search (SCAN) function is to
enable the receiver to automatically scan for Weather Alerts
on all ten (10) WX channels while the radio is in Marine
Standby status. This allows use of the communication
functions of the radio without missing a Weather Alert when:
■
■
■
■
WX Auto Search (SCAN) function is On.
WX Alert is On.
The radio is tuned to a Marine VHF channel and
has entered Power Save mode (meaning there
is no signal activity or user input for 10 seconds).
The radio software has detected that the current
WX channel signal level has dropped below
a preset minimum level or is gone completely.
Under these conditions, the software will scan the
WX channels looking for an active WX channel.
When an active WX channel is found, it will stop
the scan and use the new WX channel to look for
the standard 1050Hz alert tone.
