Owner’s Manual

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 VHF transceiver for fixed mounting on your boat. It gives you 2-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 2-way communications, in the U.S.A., the radio can provide quick access to receive eight NOAA (National Oceanographic and Atmospheric Administration) and two Canadian weather channels for alerting you to weather emergencies with a tone on a weather channel you can tune in for your area.

Introduction

Recommendations For Marine Communication FCC Information

VHF Marine Radio Protocols

NOTICES AVOID using or storing the radio at temperatures below -4°F (-20°C) or above

140°F (55°C). NEVER connect the transceiver to DC power greater than 16 volts or to

any DC source with reversed polarity. Doing so will damage the transceiver. DO NOT cut the power cables attached to the transceiver. Improper

reconnection with reversed polarity will damage the transceiver. POSITION your radio, external speakers, and cables at least three (3) feet (0.9 m)

away from your vessel’s magnetic navigation compass. CHECK your compass before and after installation to be sure that it has not introduced any deviation.

DO NOT attempt to service any internal parts yourself. Have any necessary service performed by a qualified technician.

DO NOT drop the transceiver or microphone. Doing so may crack the case or damage a waterproof seal. Once these items have been dropped, the original waterproofing cannot be guaranteed.

DO NOT use chemicals or solvents such as mineral spirits and alcohol to clean your radio. They may damage the case surfaces.

WARNING

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 25 watt maximum output of your radio isn’t sufficient for the distances you travel from the coast, consider installing 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 don’t know where you are, the Coast Guard will have difficulty finding you if you’re 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.

Sea Tow Automated Radio Check (ARC) System

Please try the Sea Tow Automated Radio Check service. Areas where the safety check service is available include the East Coast, Gulf of Mexico, Southern California, and select inland locations including the Great Lakes. The first and only boating safety program of its kind, the Sea Tow Automated Radio Check service is fully automated and allows 24 hour a day automated responses to radio check calls.

Conducting a radio check through the Sea Tow Automated Radio Check service couldn’t be simpler. All boaters need to do is tune their VHF radio to Channel 24, 25, 26, 27, 28 or 84 (channel varies by location), then key the mic and ask for a radio check. The system responds to each radio check with an automated reply including the location, and also replays the boater’s original radio transmission, allowing them to assess the strength of the signal and confirm the VHF radio is in good working order.

To find the Sea Tow Automated Radio Check service channel in an area, radio owners should visit www.seatow.com/arc. The web page allows you to search for the local channel and has an instructional video on how to use the service step by step.

VHF Marine Radio Protocols VHF Marine Radio Protocols

Procedures

Voice Calling

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.

Canadian Ship Station License

You need a Radio Operator’s Certificate if your vessel is operated in Canadian waters. Radio Operator training and certification is available from the Canadian Power Squadron. Visit their website (http://www.cps-ecp.ca/english/newradiocard.html), contact the nearest field office or write: Industry of Canada, Radio Regulatory Branch, Attn: DOSP, 300 Slater Street, Ottawa, Ontario, Canada K1A 0C8.

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.

NOTE

This device complies with part 15 of the FCC Rules. Operation is subject to the following two (2) conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.

FCC Warnings: Replacement or substitution of transistors, regular diodes, or other parts of a unique nature, with parts other than those recommended by Cobra® may cause a violation of the technical regulations of part 80 of the FCC Rules, or violation of type acceptance requirements of part 2 of the rules.

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.

Power

Try 1 watt first if the station being called is within a few miles. Try a second call after waiting two (2) minutes. If there is no answer, switch to a higher power. This will minimize interference to other users by avoiding repeated calls.

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 or on Channel 9. (Channel 9 is preferred for recreational vessel use.) You may also call on ship-to-ship channels when you know that the vessel is listening on a ship-to-ship channel.

Initial Calling on Channel 16 or 9

The use of Channel 16 is permitted for making initial contact (hailing) with another vessel. The limits on calling must be followed. Be reminded, Channel 16’s most important function is for Emergency Messages. If, for some reason, Channel 16 is congested, the use of Channel 9, especially in U.S. waters, may be used as the initial contact (hailing) channel for non-emergency communication.

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 two (2) minutes before calling again. After three (3) calling periods, wait at least 15 minutes before calling again.

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.

Station Identification

Identify, in English, your station by your FCC call sign, ship name, the state registration number, or other official number at both the beginning and end of each message.

Prohibited Communications

You MUST NOT transmit:

Q

False distress or emergency messages.

Q

Messages containing obscene, indecent, or profane words or meaning.

Q

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.

Q

•

When you are on land.

Voice Calling

To Call Another Vessel Or A Shore Installation Such As A Lock Or Bridge Tender:

Q

Make sure your radio is On.

Q

Select Channel 16 and listen to make sure it is not being used.

NOTE

Channel 9 may be used by recreational vessels for general-purpose calling. This frequency should be used whenever possible to relieve congestion on Channel 16.

Q

When the channel is quiet, press the Talk button and call the ship you wish to call. (Hold the microphone a few inches 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].”

Q

Once contact is made on the calling channel, you must switch to a proper working channel. See the channel listing on page 66 through 78.

Maritime Mobile Service Identity (MMSI)

A MMSI Number Is Available In The U.S.A. From Two (2) Sources:

Q

U.S. Power Squadron www.usps.org

Q

BoatUS: 1-800-563-1536 – www.boatus.com/mmsi

NOTE

The above references are for recreational vessels only. Commercial vessels should contact the FCC.

An MMSI is a nine (9) digit number used on a marine radio capable of using digital selective calling (DSC). It is used to selectively call other vessels or shore stations and is similar to a telephone number.

After each transmission, say “OVER” and release the microphone Push to Talk (PTT) button. This confirms that the transmission has ended. When all communication with the other vessel is totally completed, end the message by stating your call sign and the word “OUT.” Remember, it is not necessary to state your call sign with each transmission, only at the beginning and end of the message.

NOTE

For best sound quality at the shore station or other vessel receiving your call, hold the microphone/speaker at least 2 in. (51 mm) from your mouth and slightly off to one (1) side. Speak in a normal tone of voice.

For your CobraMarine maritime mobile service identity (MMSI) number. See page 41 for instructions on how to enter it.

In Canada, Contact:

Q

Industry Canada Spectrum Management Office (only available on the Internet): www.ic.gc.ca and search for “MMSI”.

To Obtain An MMSI Number Outside The U.S.A.:

Users can obtain an MMSI from their country’s telecommunications authority or ship registry. This may involve amending or obtaining a ship station license.

Digital Selective Calling (DSC)

Digital selective calling is a semi-automated system for establishing a radio call. It has been designed by the International Maritime Organization (IMO) as an international standard for VHF, MF, and HF calls and is part of the Global Maritime Distress and Safety System (GMDSS).

The DSC system allows mariners to instantly send a distress call with GPS position coordinates (requires a GPS receiver to be connected to the radio)

WARNING

This equipment is designed to generate a digital maritime distress and safety signal to facilitate search and rescue. To be effective as a safety device, this equipment must be used within communication range of a VHF marine channel to distress and safety watch system. The range of the signal may vary, but under normal conditions should be approximately 20 nautical miles.

VHF Marine Radio Protocols VHF Marine Radio Protocols

Radiotelephone Calls

Emergency Messages And Distress Procedure

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 Coast Guard 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, Coast Guard or Coast Guard Auxiliary craft may be dispatched.

In an event, do not communicate with the Coast Guard as soon as you experience difficulties or before your situation becomes an emergency. Use the emergency (Distress) 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. Use channel 16 to communicate your emergency message. Make sure you transmit on high power. If you are merely out of gas, do not send an emergency distress message. Drop your anchor and call a friend or local marina to bring the fuel you need or to give you a tow.

•

Marine Emergency Signals

The three (3) spoken international emergency signals are:

MAYDAY

The distress signal MAYDAY is used to indicate that a station is threatened by grave and imminent danger and requests immediate assistance.

PAN

The urgency signal PAN is used when the safety of the vessel or person is in jeopardy. (This signal is properly pronounced pahn.)

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 (3) times prior to the message.

If You Hear A Distress Call

You must give any message beginning with one (1) 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.

And Distress Procedure

Emergency Messages And Distress Procedure

Marine Distress Procedure

Speak slowly — clearly — calmly.

1. Make sure your radio is On.

2. Select VHF Channel 16.

3. Press Talk button and say:

“MAYDAY — MAYDAY — MAYDAY.” (Or “PAN — PAN — PAN,” or “SECURITE — SECURITE — SECURITE.”)

4. Say:

“THIS IS [your vessel name or call sign].”

5. Say:

“MAYDAY (or “PAN” or “SECURITE”) [your vessel name or call sign].

6. Tell where you are:

(what navigational aids or landmarks are near).

7. State the nature of your distress.

8. State the kind of assistance needed.

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, color, 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.

English

Keep the radio nearby. Even after your message has been received, the Coast Guard can find you more quickly if you can transmit a signal for a rescue boat to hone in on.

For Example

“Mayday — Mayday — Mayday” “This is Corsair — Corsair — Corsair” [or “Illinois 1234 AB” three (3) times] “Mayday Corsair (or Illinois 1234 AB)” “Navy Pier bears 220 degrees magnetic — distance five (5) miles” “Struck submerged object and flooding — need pump and tow” “Four adults, three children aboard — no one injured” “Estimate we will remain afloat one-half (

⁄2) hour” “Corsair (or Illinois 1234 AB) is 26 foot sloop with blue hull and tan deck house” “I will be listening on Channel 16” “This is Corsair (or Illinois 1234 AB)” “Over”

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.

Marine Distress Procedure – DSC

Digital Selective Calling (DSC) is a semi-automated system that will allow you to press the Distress button from any routine to make a distress call. When the distress button is pressed, all other channels go to Standby mode and allow the digitally encoded “pre-programmed” message to take precedence. Important information such as your MMSI number, position and name will be transmitted on Channel 16. The distress alarm will sound for two (2) minutes or until the alarm is cleared.

The DSC system allows you to choose a “pre-programmed” distress call such as: “Man Overboard, Sinking, Collision.” There are many pre-programmed choices to choose from. If a GPS is connected to your radio, your coordinates will also be sent to the Coast Guard as well as to other vessels that are within range of the transmission. DSC calling also allows the user to initiate and receive distress, urgent, safety, routine, position request, position send and group calls between vessels equipped with DSC capable radios.

Antenna Requirements And Attachment

Antenna Requirements

Your CobraMarine VHF radio requires an external marine antenna to send signals into the air and to receive them. The radio is arranged to use any of the popular marine VHF antennas, but it is up to you to choose which antenna to use.

Since it represents the link between your radio and the outside world, Cobra you purchase only the best quality antenna, coaxial cable, and connectors. This is best accomplished with the advice and guidance of a knowledgeable dealer who can assess the variables involved with your particular boat and preferences.

WARNING

Compliance with FCC requirements for Radio Frequency Exposure is the responsibility of both the antenna installer and the radio operator.

Safe Maximum Permissible Exposure (MPE) Radius

To avoid health hazards from excessive exposure to RF energy, FCC OET Bulletin 65 establishes an MPE radius of 11’ (3.3 m) for the maximum power of your radio with an antenna having a maximum power gain of 9 dBi. This means that all persons must be at least 11’ (3.3 m) away from the antenna when the radio is transmitting.

Installation Requirements

A) An omnidirectional antenna with a gain not greater than 9 dBi must

be mounted at least 16.4’ (5 m) above the highest deck where people may be during radio transmissions, measured vertically from the lowest point of the antenna. This provides the minimum separation distance to comply with RF exposure requirements and is based on the MPE radius of 10’ (3 m) plus the 6.6’ (2 m) height of an adult.

B) For vessels without structure to mount the antenna as described in A,

it must be mounted as follows AND all persons must be outside the 10’ (3 m) MPE radius during radio transmissions. The antenna must be mounted so that its lowest point is at least 3.3’ (1 m) vertically above the heads of all persons during radio transmissions.

•

Radio Operator Requirements

Do not transmit when anyone is within the MPE radius of the antenna unless that person or persons are shielded from the antenna by a grounded metallic barrier. This is especially important on vessels with antennas mounted as described in B where no one may be within 11’ (3.3 m) horizontally from the base of the antenna during transmissions.

FAILURE TO OBSERVE THE ABOVE LIMITS MAY EXPOSE THOSE WITHIN THE MPE RADIUS TO RF ENERGY ABSORPTION IN EXCESS OF THE FCC MAXIMUM PERMISSIBLE EXPOSURE. IT IS THE RADIO OPERATOR’S RESPONSIBILITY TO INSURE THAT MPE LIMITS ARE HEEDED AND THAT NO ONE IS WITHIN THE MPE RADIUS DURING TRANSMISSIONS.

Coaxial Cable Socket

Antenna Lead Attachment

Once the antenna is installed, the Coaxial Cable Lead can

be attached to the socket at the back of the transceiver.

CAUTION

Attempting to transmit without an antenna attached will damage your CobraMarine VHF radio.

External Devices And Connections

Your CobraMarine VHF radio is set up to connect auxiliary devices for navigation, convenience, and added versatility. As is the case with the antenna, choosing these devices is best done with the advice and guidance of a knowledgeable dealer. Standard connectors are provided on the front and back of the transceiver.

External Speaker (Not Included)

An External Speaker can provide greater volume to hear messages than the speaker incorporated in the CobraMarine microphone/speaker.

To Install An External Speaker:

1. Connect the wires to the External Speaker as follows:

Orange wire - +Positive connection Black wire - -Negative connection (Black wire is common shared -Negative for

the External Speaker and PA output)

2. Make sure to solder, crimp, or twist the wires together firmly and use shrink

tubing or electrical tape to waterproof the connection.

Public Address Speaker (Not Included)

At times, it may be handy to hail other boats or give instructions to line handlers on the dock. Your CobraMarine VHF radio can be switched to operate in the Public

Address mode through an attached PA speaker. To Install A Public Address (PA) Speaker:

1. Connect the wires to the PA Speaker as follows:

Red wire - +Positive connection Black wire - -Negative connection (Black wire is common shared -Negative for the

External Speaker and PA output)

2. Make sure to solder, crimp, or twist the wires together firmly and use shrink

tubing or electrical tape to waterproof the connection.

Global Positioning System (GPS) Device (Not Included)

Your Cobra Marine radio does not include a built-in GPS receiver. After connecting an external 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.

A GPS input connector has been provided to allow connection to a external GPS receiver.

To Install A GPS Device:

1. Install the GPS device in a convenient location according to its manufacturer’s

directions.

2. Or plug-in the optional Cobra C.P.S. CM300-005 (Cobra Positioning System) into the

provided 2.5mm jack.

3. Or using the supplied 2-wire adapter wire as follows:

Yellow wire = NMEA 0183 + Data in Green wire = NMEA 0183 - Data in

NOTE

Satellite acquisition time is dependent on the GPS antenna mounting location. If the acquisition takes too long, relocate the external GPS receiver (CM300-005).

NOTE

GPS data input is as follows:

• Input voltage (peak to peak): 10V

• Maximum data rate: 4800 baud

• Impedance: 4KΩ
