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
5 cm (2 inches) away from yourself and others when transmitting.
DO NOT transmit more than 40% of the time the radio is in use — 40% 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 recommended
RF exposure limits or create other dangerous conditions.
NOTICE
Your radio is waterproof only when the batteries are properly installed.
AVOID using the radio below -20˚C and above +40°C.
AVOID storing the radio below -20˚C and above +60°C.
KEEP your radio at least 0,9 m (3 ft) 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.
nUse only the Cobra charger to recharge lithium-ion (LiON) batteries in the radio.
nDo not short circuit the battery pack.
nWhen replacing the batteries, dispose of the old batteries properly. Batteries
may explode if disposed of in a fire.

Nothing Comes Close to a Cobra®
FCC Licensing Information
Licensing Information •
The radio operates on all currently allocated marine channels and is switchable for
use according to International, Canadian or U.S.A. regulations. It features instant
access to emergency Channel 16 by pressing one key.
Station License
The UK requires a ship’s radio license and a marine radio operator’s certificate before
transmitting equipment can be used aboard a vessel. Other European countries have
specific requirements of their own.
For detailed information and applications, contact the Radio Licensing Centre run
by OFCOM in the UK. In other countries, contact the relevant national postal
or telecommunications authority.
Canadian or U.S.A. Station License
If your vessel will be entering the sovereign waters of Canada or the U.S.A.,
you should contact Industry of Canada, Radio Regulatory Branch or the U.S. FCC
(Federal Communications Commission) for licensing and operating information.
Radio Call Sign
A radio call sign is included as part of the ship’s radio license in the UK.
Other countries may have different practices; contact your local regulatory
authority for information.
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 transmitting frequencies in
your radio are reserved for maritime use; any frequency you use for transmission
must be specifically included on your ship’s license. 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. The use of ATIS is prohibited outside the
European inland waterways covered by the Basel Agreement.
4English
General Precautions
Introduction
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 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 coastguard does not endorse mobile phones as substitutes for marine radios.
They generally cannot communicate with rescue vessels and, if you make a distress
call on a mobile phone, only the party you call will be able to hear you. Additionally,
mobile phones may have limited coverage over water and can be hard to locate.
If you do not know where you are, the coastguard will have difficulty finding you if
you are using a mobile phone.
However, mobile phones can have a place on board where mobile 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 45 before putting your radio into service.

2. Disposal of a battery into re or a hot oven, or
mechanically crushing or cutting of a battery,
that can result in an explosion;
3. Leaving a battery in an extremely high temperature
surrounding environment that can result in an
explosion or the leakage of ammable liquid or gas;
4. A battery subjected to extremely low air pressure

Initial Charge
The Cobra-provided LiON battery pack may be charged at
home, in a car or in a boat using the appropriate 12V or
220V 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 220V power source.
3. Remove battery pack 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 five (5) to six (6) hours
before use. The light will change back to green when the
battery is fully charged.
WARNING
Only the rechargeable LiON 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 lithium-ion
(LiON) battery pack from freezing to obtain best
performance from the battery pack.

NOTICE
Lithium-ion (LiON) batteries are toxic. Please dispose
of properly. Some marine suppliers and electronics
retailers accept old battery
packs for recycling and
some municipal waste disposal
agencies have special
provisions for battery disposal.
Alkaline Batteries
The alkaline battery tray acts as a backup or “Emergency”
power source should the battery pack run low on power and
need to be recharged. The radio will transmit at full power
when using five (5) new AA alkaline batteries.
