General Precautions  
Before assembling and using your CobraMarineVHF radio,  
please read these general precautions and warnings.  
The following WARNINGS and CAUTIONS will make you aware of RF exposure  
hazards and how to assure you operate the radio within the recommended RF  
exposure limits established for it.  
Warning and Caution Statements  
WARNINGS  
To make the most of this radio, it must be assembled and used properly.  
Please read the assembly and operating instructions carefully before assembling  
and using it. Special attention must be paid to the WARNING and CAUTION  
statements in this manual.  
Your CobraMarineradio 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 (beyond recommended  
allowable limits for occupational use):  
WARNING  
ALWAYS hold the radio, especially the antenna, at least 5 cm away from  
you when you are transmitting.  
Statements identify conditions that could result in personal injury or loss of life.  
NEVER allow the antenna to touch any part of your body when transmitting.  
KEEP the radio and antenna at least as far from bystanders as from yourself.  
CAUTION  
Statements identify conditions that could cause damage to the radio  
or other equipment.  
DO NOT operate the radio without the supplied antenna or a Cobra Electronics  
Corporationauthorized replacement attachment. In addition to the RF energy  
exposure hazard, doing so may damage the radio.  
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 icon shows on the LCD screen.  
ALWAYS use only Cobra Electronics Corporationauthorized accessories  
(antennas, batteries, belt clips, etc.).  
DO NOT operate the radio where RF energy generated during transmission  
may cause electromagnetic interference or incompatibility with other devices  
or systems. This includes aircraft, blasting sites and hospitals.  
TURN OFF the radio in explosive atmospheres and where signs are posted  
prohibiting radio transmissions.  
Failure to observe any of these warnings may cause you to exceed  
recommended RF exposure limits or create other dangerous conditions.

Introduction  
Recommendations for Marine Communication  
CAUTIONS  
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  
5 watt maximum output of your radio isn’t sufficient for the distances you travel from  
the coast, consider installing a CobraMarinefixed mount radio with up to 25 watts of  
Your radio is only waterproof when the antenna and batteries  
are properly installed.  
AVOID using or storing the radio at temperatures below -20˚C  
or above 60˚C.  
KEEP your radio at least 1m away from your vessel’s magnetic  
navigation compass.  
If you will be going far offshore, you should consider adding even more powerful  
radio equipment such as HF single side band or satellite radio for your vessel.  
DO NOT attempt to service any internal parts yourself. Have any  
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 don’t know where you are, the coastguard will have difficulty finding you if  
you’re using a mobile phone.  
necessary service performed by a qualified technician.  
This radio is supplied with six NiMH (Nickel-Metal Hydride)  
rechargeable batteries.  
Use only the CobraMarinecharger to recharge  
NiMH batteries in the radio.  
I
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.  
I
Do not short circuit the battery pack.  
I
When replacing the batteries, dispose of the old batteries properly.  
NiMH batteries may explode if disposed of in a fire.  
I
The charger is to be used for charging purposes only.  
It is not to be used during normal operation.  
Changes or modifications to your radio MAY VOID its compliance with  
government rules and make it illegal to use.

VHF Marine Radio Protocols  
VHF Marine Radio Protocols  
Licensing Information  
VHF Marine Radio Procedures  
Maintain Your Watch  
Whenever your boat is underway, the radio must be turned On and  
be tuned to Channel 16 except when being used for messages.  
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.  
CobraMarineVHF radios comply with the U.S. FCC (Federal Communications  
Commission) requirements that regulate the Maritime Radio Service.  
Power  
Try 1 watt first if the station being called is within a few kilometres. If there  
is no answer, switch to a higher power. This will conserve your battery  
and minimize interference to other users.  
Station License  
The UK requires a ships 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 Royal Mail in the UK. In other countries contact the relevant national postal or  
telecommunications authority.  
Calling Coast Stations  
Call a coast station on its assigned channel. You may use Channel 16  
when you do not know the assigned channel.  
Calling Other Vessels  
Call other vessels on Channel 16. You may also call on ship-to-ship channels  
Canadian or U.S.A. Station License  
when you know that the vessel is listening on a ship-to-ship channel.  
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. Federal  
Communications Commission for licensing and operating information.  
Limits on Calling  
You must not call the same station for more than 30 seconds at a time.  
If you do not get a reply, wait at least 2 minutes before calling again.  
After three calling periods, wait at least 15 minutes before calling again.  
Radio Call Sign  
A radio call sign is included as part of the ships radio license in the UK.  
Other countries may have different practices; contact your local regulatory  
authority for information.  
Change Channels  
After contacting another station on a calling channel, change immediately  
to a channel which is available for the type of message you want to send.  
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.  
Station Identification  
Identify your station by your call sign, ship name or other official number  
at both the beginning and end of each message.  
Prohibited Communications  
You MUST NOT transmit:  
I
False distress or emergency messages.  
I
Messages containing obscene, indecent or profane words or meaning.  
I
General calls, signals or messages (messages not addressed to a particular  
station) on Channel 16, except in an emergency or if you are testing your radio.  
I
When you are on land.

Voice Calling  
Radiotelephone Calls  
VHF Marine Radio Protocols  
VHF Marine Radio Protocols  
Radiotelephone Calls  
Boaters may make and receive radiotelephone calls to and from any number on  
the telephone network by using the services of public coast stations. Calls can be  
made — for a fee — between your VHF radio and telephones on land, sea and in the  
air. See pages 14 – 23 for the public correspondence (marine operator) channels.  
Voice Calling  
To call another vessel or a shore installation such as a lock or bridge tender:  
I
Make sure your radio is On.  
I
Select Channel 16 and listen to make sure it is not being used.  
I
If you plan to use these services, consider registering with the operator of the  
public coast station that you plan to work through. Those services can provide  
you with detailed information and procedures to follow.  
When the channel is quiet, press the Talk button and call the ship you  
wish to contact. (Hold the radio at least 5 cm from your face and speak  
directly into it in a normal tone of voice — clearly and distinctly.) Say  
“[name of station being called] THIS IS [your vessel’s name or call sign]”.  
CAUTION  
I
Once contact is made on the calling channel, you must switch to a proper  
working channel. See the channel listing on page 14 – 23.  
You may disclose privileged information during a radiotelephone call.  
Keep in mind that your transmission is NOT private, as it is on a regular  
telephone. Both sides of the conversation are being broadcast and can be  
heard by anyone who has a radio and tunes to the channel you are using.  
For Example  
The vessel Corsair calling the vessel Vagabond:  
Corsair: “Vagabond, this is Corsair.”  
Vagabond: “Corsair, this is Vagabond. Reply 72 (or any proper working channel).”  
Corsair: “72.” or “Roger.”  
I
After communications are completed, each vessel must sign off with its  
call sign or vessel name and switch to Channel 16.  
NOTE  
For the best sound quality at the station you’re calling, hold the radio  
at least 5 cm from your mouth and slightly off to one side. Speak in  
a normal tone of voice.

Emergency Messages and Distress Procedure  
Marine Emergency Signals  
The three spoken international emergency signals are:  
MAYDAY  
The ability to summon assistance in an emergency is the primary reason  
to have a VHF marine radio. The marine environment can be unforgiving,  
and what may initially be a minor problem can rapidly develop into a  
situation beyond your control.  
The distress signal MAYDAY is used to indicate that a station is threatened  
by grave and imminent danger and requests immediate assistance.  
The coastguard monitors Channel 16, responds to all distress calls,  
and coordinates all search and rescue efforts. Depending on the availability  
of other capable vessels or commercial assistance operators in your vicinity,  
coastguard or coastguard auxiliary craft may be dispatched.  
PAN PAN  
The urgency signal PAN PAN is used when the safety of the vessel or person  
is in jeopardy. (This signal is properly pronounced pahn-pahn.)  
In any event, do communicate with the coastguard as soon as you experience  
difficulties and before your situation becomes an emergency. Use the emergency  
message procedures only after your situation has become grave or you are faced  
with a sudden danger threatening life or property and requiring immediate help.  
If you are merely out of fuel, do not send an emergency message. Drop your  
anchor and call a friend or marina to bring the fuel you need or give you a tow.  
SECURITE  
The safety signal SECURITE is used for messages about the safety of navigation or  
important weather warnings. (This signal is properly pronounced see-cure-it-tay.)  
When using an international emergency signal, the appropriate  
signal is to be spoken three times prior to the message.  
If You Hear a Distress Call  
You must give any message beginning with one of these signals priority  
over any other messages. ALL stations MUST remain silent on Channel 16  
for the duration of the emergency unless the message relates directly to  
the emergency.  
If you hear a distress message from a vessel, stand by your radio. If it is  
not answered, YOU should answer. If the distressed vessel is not nearby,  
wait a short time for others who may be closer to acknowledge. Even if  
you cannot render direct assistance, you may be in a position to relay  
the message.

VHF Marine Radio Protocols  
Keep the radio nearby. Even after your message has been received, the coastguard can  
find you more quickly if you can transmit a signal for a rescue boat to home in on.  
Marine Distress Procedure  
Speak slowly — clearly — calmly.  
1. Make sure your radio is On.  
For Example  
2. Select VHF Channel 16.  
“Mayday — Mayday — Mayday”  
“This is Corsair — Corsair — Corsair”  
“Mayday Corsair”  
3. Press Talk button and say:  
“MAYDAY — MAYDAY — MAYDAY”  
(or “PAN PAN — PAN PAN — PAN PAN”  
or “SECURITE — SECURITE — SECURITE”)  
“Point Lynas bears 220 degrees magnetic — distance 5 kilometres”  
“Struck submerged object and flooding — need pump and tow”  
“Four adults, three children aboard — no one injured”  
“Estimate we will remain afloat one-half hour”  
“Corsair is an 8 metre sloop with blue hull and tan deck house”  
“I will be listening on Channel 16”  
4. Say:  
“THIS IS [your vessel name or call sign].”  
5. Say:  
“MAYDAY” (or “PAN PAN” or “SECURITE”)  
[your vessel name or call sign].  
6. Tell where you are:  
“This is Corsair”  
(Your position or what navigational aids or landmarks are near.)  
“Over”  
7. State the nature of your distress.  
8. State the kind of assistance needed.  
It is a good idea to write out a script of the message form and post it where you  
and others on your vessel can see it when an emergency message needs to be sent.  
9. Give number of persons aboard and conditions of any injured.  
10. Estimate present seaworthiness of your vessel.  
11. Briefly describe your vessel (length, type, colour, hull).  
12. Say:  
“I WILL BE LISTENING ON CHANNEL 16.”  
13. End message by saying:  
“THIS IS [your vessel name or call sign] OVER.”  
14. Release Talk button and listen. Someone should answer.  
If not, repeat the call, beginning at item 3 above.  
For medical problems such as crew hit by sailboat boom or heart  
trouble, make a PAN PAN call as above with the word medico added.  
“PAN PAN MEDICO — PAN PAN MEDICO — PAN PAN MEDICO”  
The coastguard will try to link you to a doctor who can give  
expert advice and evaluate the need for evacuation.

(distress and safety).  
Intership Safety  
Channel 6  
Ship-to-ship safety messages and for search and rescue messages to  
coastguard ships and aircraft.  
Navigational  
Channels 13, 67  
Channels are available to all vessels. Messages must be about navigation,  
including passing or meeting other vessels. These are also the main working  
channels for most locks and drawbridges. You must keep your messages  
short and power output at no more than 1 watt.  
On-Board Communication  
Channel 15  
Used for communication between parts of large ships.  
Digital Selective Calling  
Channel 70

NOTE  
Many of the plain numbered channels, such as 01, 02 and 03, transmit and  
receive on different frequencies. This is termed duplex operation. The rest of  
the plain numbered channels and all of the A channels, such as 01A, 03A,  
and 04A, transmit and receive on a single frequency, which is termed simplex  
operation. Your radio automatically adjusts to these conditions. When in simplex  
operation, the A icon will appear on the LCD (see illustration on page A2).  
All the listed channels are pre-programmed at the factory according to  
international regulations, those of Industry Canada (Canada) and those  
of the FCC (U.S.A.). They cannot be altered by the user nor can modes  
of operation be changed between simplex and duplex. In some countries,  
additional channels are available. These can be programmed on the  
radio by the local dealer or distributor.

On-Off Power/Volume Knob  
Getting Started  
Refer to the foldout on the front cover of this manual to identify the various  
controls and indicators on your radio.  
Throughout this manual you will be instructed to press or to press and hold buttons  
on the radio. Press means a momentary press, then release; press and hold means  
to hold the button down.  
Volume  
The On-Off Power/Volume knob also controls the speaker  
Volume. The Volume adjustment applies only to what you  
hear from the speaker and does not affect the Volume of  
your outgoing messages, which is controlled by the  
circuitry of your radio.  
Whenever you press any button except the Talk button on your radio, a brief tone  
(beep) will sound to confirm the button press. With all button presses, the appropriate  
icon will appear on the LCD and the backlight will turn On. The backlight will stay  
On for five seconds after the button is released.  
At times you will hear two other sounds. Two beeps will sound to confirm your  
setting changes and three beeps will sound to notify you of an error.  
To increase the volume:  
1. Turn the On-Off Power/Volume knob clockwise.  
To decrease the volume:  
1. Turn the On-Off Power/Volume knob anticlockwise.  
Squelch

2. Turn the On-Off Power/Volume knob clockwise  
until you hear and feel a click.  
2. Turn the Squelch knob clockwise until the hissing  
sound stops. Turning the Squelch knob further clockwise  
will filter weak and medium strength signals until only the  
strongest signal can get through at its highest setting.  
When the radio is powered On, a brief tone will sound,  
the display backlight will turn On, and the display will  
show all icons for two seconds. All buttons will be  
inoperative during these two seconds.  
After two seconds, the radio will return to the settings  
in effect when it was last powered Off, the LCD will show  
the appropriate icons, and all controls will be operative.  
The radio will then be in Standby mode.  
On-Off Power/Volume Knob  
To receive weaker signals, turn the Squelch knob  
anticlockwise.  
If the squelch is set so you can hear a continuous hissing  
sound, the scan and tri-watch functions will be blocked.

International/Canada/U.S.A. Channel Maps  
Transmit Power Output  
Three sets of VHF Channel Maps have been established for marine use  
internationally, in Canada and in the U.S.A. Most of the channels are the  
same for all three maps, but there are definite differences (see table on  
pages 14 – 23). Your radio has all three maps built into it and will  
operate correctly in whichever area you choose.  
Your radio can Transmit selectively at 1 or 5 watts of power.  
Cobra Electronics Corporationsuggests you maintain the  
low power setting for short-range communications, to  
conserve battery life and to avoid overpowering nearby  
stations with your 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.  
High Power Mode  
To set your radio for the area  
in which you will be using it:  
UIC Button  
To toggle between the High and Low Power modes:  
1. Press the High/Low Power button. The LCD will show  
which mode is in effect.  
Some channels are restricted to use at a maximum of  
1 watt. Your radio will automatically set the power  
to Low Power mode when you select those channels.  
1. From Standby mode, press and hold the UIC  
button for two seconds. The radio will shift  
one channel map and the Active Channel  
Map icon on the LCD will show the change  
on the LCD.  
High/Low Power Button  
Active Channel Map Icon  
Repeat step 1 to shift to the next channel map(s).  
While using the U.S.A. channel map, if, in an emergency,  
you need to increase the output power on Channel 13 and  
Channel 67 for your signal to be heard, you can override  
the Low Power mode by pressing and holding the High/  
Low Power button.  
Channels  
Your radio will receive and transmit VHF signals  
on the Channel indicated on the LCD. You can change  
the Channel at any time using the Channel Up and  
Channel Down buttons.  
Channel Up/Down Buttons  
Backlight  
To change channels:  
The LCD will be illuminated by the Backlight when any key is pressed  
1. Press the Channel Up or Channel Down button.  
and will remain on for five seconds after the button is released.  
If you are on Channel 88, pressing the Channel Up  
button will advance to Channel 1. If you are on  
Channel 1, pressing the Channel Down button  
will advance to Channel 88.  
You can hold the Channel Up or Channel Down  
button for fast advance.  
If you need to turn On the backlight  
without disturbing any settings:  
Backlight/Key Lock Button  
1. Press the Backlight/Key Lock button. The backlight  
will remain On for ten seconds.  
If the backlight is On, a press of the Backlight/Key Lock  
button will turn it Off.  
Currently on Channel 88  
The beep sound will occur only at the first press  
of the button and not during 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.
