Introduction
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 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.
Global Positioning Sytem (GPS)
Your Cobra Marine radio includes a built-in GPS receiver. Your position will be continuously
indicated on the LCD and, most importantly, it will be included automatically with any DSC
Distress message you may need to send. That will take the “search” out of “search and
rescue”.

General Precautions
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 qualied technician.
This radio is supplied with a lithium-ion (LiON) rechargeable battery pack.
QUse only the Cobra charger to recharge lithium-ion (LiON) batteries in the radio.
QDo not short circuit the battery pack.
QWhen replacing the batteries, dispose of the old batteries properly. Batteries
may explode if disposed of in a re.
CAUTION Risk of explosion if battery is replaced by an incorrect type. Dispose of used
batteries according to the instructions.
Changes or modications 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 aoat 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 sufcient for the distances you travel from
the coast, consider installing a Cobra Marine xed 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 difculty
nding 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.

Channel Up/Down Buttons
Your radio will Receive (Rx) and Transmit (Tx) VHF signals on
the channel indicated on the LCD display. You can change the
channel at any time using the Channel Up/Down buttons.
To Change Channels:
Press the Channel Up/Down button.
If you are on Channel 88, pressing the Channel Up
button will advance to Channel 01. If you are on Channel
01, pressing the Channel Down button will advance to
Channel 88.
You can press and hold the Channel Up/Down button
for 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.
High/Medium/Low (H/M/L) Power Selection
Your radio can transmit selectively at 1, 3 or 6 watts of power.
Cobra suggests you maintain the low power setting for short-
range communications. You will conserve battery life and avoid
overpowering nearby stations with a low power setting 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 H-M-L Power Modes:
Press the MORE soft key until the screen shows as illustrated.
Pres the H-M-L soft key to set the power 1W, 3W, or 6W.
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.
NOTE
A few channels are Receive only and will not transmit in
these channels.
