Our Thanks to You •
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.

Recommendations for
Marine Communication
Recommendat ons for Mar ne Commun cat on •
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 6 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 uard 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 uard 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.
4English
General recautions
Introduction
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 a lithium-ion (LiON) rechargeable battery pack.
■Use only the Cobra charger to recharge lithium-ion (LiON) batteries in the radio.
■Do not short circuit the battery pack.
■When replacing the batteries, dispose of the old batteries properly. 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.

Coast uard alerts are broadcast on Channel 16. You must 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

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 uard 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.
