General Precautions •
The following WARNINGS and NOTICE information will make you aware of RF exposure hazards and
how to assure you operate the radio within the FCC RF exposure limits established for the radio.
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 (5 cm) away from yourself and others when transmitting.
DO NOT operate with more than a duty cycle of 5% transmit, 5% receive and
90% standby. 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 where it 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.

FCC Licensing Information
FCC Licensing Information •
Cobra Marine VHF radios comply with the FCC (Federal Communications Commission)
requirements that regulate the Maritime Radio Service.
This Cobra Marine radio incorporates a VHF FM transceiver designed for use in the frequency
range of 156.025 to 163.275 MHz. It has a switchable RF output power of one (1), three (3)
or six (6) watts.
The transceiver is capable of Class-D (Digital Selective Calling) operation in accordance with
CFR Part 47, Section 80,225.
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.
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 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.

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 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.
CAUTION Risk of explosion if battery is replaced by an incorrect type. Dispose of used
batteries according to the instructions.
Changes or modifications 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 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 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.

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.
WARNING
Never attempt to recharge alkaline batteries. They are not
made to be recharged, and should be disposed of
in a proper manner.

Batteries and Charger
Charging
The Cobra-provided LiON battery pack may be charged at home,
in a car or in a boat using the appropriate 12V or 120V 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 120V power source.
3. Remove the 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 charge light will turn off when the battery is fully
charged.
WARNING
The charger provided for this radio is only to be used to
charge the battery pack provided. Do not charge any other
type of batteries in the charger as fire, explosion or battery
damage may occur. Avoiding extreme temperatures will
also help prolong the life of the battery pack for the radio.

Bluetooth®wireless technology is a standard which has been developed for use in mobile
phones and other devices. This process of linking your mobile phone and this radio requires
a one-time “pairing” after which the two devices can be “connected” when they are within
range. When connected, this radio can act as the speaker and microphone of your mobile
phone while your phone is stowed in a safe and dry location.
This programming section shows you how to complete the pairing process. It also shows you
how to change some settings related to the Bluetooth functionality of your radio.
Bluetooth Radio On/Off
This setting allows you to turn On and Off the small Bluetooth
radio inside this VHF radio. The default setting is OFF. Turning it
Off can save some power. It can easily be switched On at any time.
1. From the Standby screen, press the MORE soft key until the
Bluetooth soft key icon appears.
2. Press the Bluetooth icon soft key.
3. Press the Channel Up/Down soft keys to select Bluetooth and
then press Enter.
4. Press the Channel Up/Down soft keys to select On or Off.
5. If set ON, the radio will go to discover mode as long as it’s not
already connected to a mobile phone.

1. If Bluetooth is turned on, the MR HH600 is automatically
ready to pair to your mobile phone.
2. Open the Bluetooth setting on your mobile phone and look for a
new device called “MR HH600”.
3. Select “MR HH600” on your mobile phone and wait to
connect. If prompted use the code “0000”.
