Owner’s Manual

Nothing Comes Close to a Cobra®

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 all NOAA (National Oceanographic and Atmospheric

Administration), including two Canadian weather channels for alerting you to

weather emergencies with a tone on a weather channel you can select for your area.

Introduction

Nothing Comes Close to a Cobra®

Important Safety Information

3

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 and KEEP yourself and all others on your vessel the required

distance away from the antenna while transmitting. See page 31 in the

antenna requirements section for further information.

DO NOT operate the radio without a proper antenna or equivalent

dummy load attached. Doing so may expose you to excessive RF

energy and will 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 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 connect the transceiver to AC power. It can be a fire hazard, may

cause an electric shock and may damage the transceiver.

NEVER mount 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

FCC RF exposure limits or create other dangerous conditions.

NOTE

Throughout this manual, the term “Transceiver” will be used to identify the

main unit containing the LCD screen and controls. The term “Radio” will be

used to identify the entire equipment including transceiver, microphone,

antenna and any attached external speakers.

Recommendations for

Marine Communication

NOTICE

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

above 140°F (60°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 3 ft (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/speaker. 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.

Changes or modifications to your radio MAY VOID its compliance with FCC (Federal

Communication 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 near-shore

voyages. If the 25 watt maximum output of your radio is not sufficient for the

distances you travel from the coast, consider installing a more powerful radio 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 onboard where cellular coverage

is available — to allow social conversations and keep the marine frequencies

uncluttered and available for their intended use.

FCC Licensing Information •

CobraMarine VHF radios comply with the FCC (Federal Communication Commission)

requirements that regulate the Maritime Radio Service.

This CobraMarine radio incorporates a VHF FM transceiver designed for use in

the frequency range of 156.025 to 163.275 MHz. It requires 13.8 volts DC and

has a switchable RF output power of one (1) or 25 watts.

The radio is capable of Class-D DSC (Digital Selective Calling) operation.

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 that can be

accessed by pressing one key.

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 a 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/formpage.html. 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.

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.

VHF Marine Radio

Procedures

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 conserve your battery and 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, vessel name and the state

registration number, at both the beginning and at the end of the message.

Prohibited Communications

You MUST NOT transmit:

 False distress or emergency messages.

 Messages containing obscene, indecent or profane language.

 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.

 When you are on land.

Voice Calling •

To Call Another Vessel or Shore Installation (e.g. Lock or Bridge Tender):

 Make sure your radio is On.

 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.

 When the channel is quiet, press the Talk button and call the vessel you wish

to call. (Hold the microphone/speaker 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].”

 Once contact is made on the calling channel, you must switch to a proper

working channel. See the channel listing on page 14 through 15.

VHF Marine Radio Protocols

Digital Selective Calling (DSC)

The vessel Corsair calling the vessel Vagabond:

Corsair: “Vagabond, this is Corsair (station license number call sign).”

Vagabond: “Corsair, this is Vagabond. Over.”

Corsair: “Vagabond go to working Channel 68. Over.”

Both parties switch over to the agreed upon working channel....

Corsair: “Vagabond I need to talk to you about... Over.”

Vagabond: “Corsair in answer to your question about... Over.”

Corsair: “Vagabond, thanks for the information about... (call sign and out).”

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.

Digital Selective Calling (DSC) •

Digital selective calling (DSC) 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).

DSC will eventually replace aural (listening) watches on distress frequencies

and will be used to announce routine and urgent maritime safety information

broadcasts. Until DSC is fully implemented, it is still necessary to maintain a

listening watch on Channel 16.

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)

to the Coast Guard and other vessels within range of the transmission.

DSC also allows mariners to initiate and receive distress, urgent, safety,

routine, position request, position send and group calls between vessels

equipped with DSC capable radios.

VHF Marine Radio Protocols

Maritime Mobile Service Identity (MMSI) •

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.

For your CobraMarine radio to operate in the DSC mode, you must enter your

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 only within communication range

of a shore-based 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.

Radiotelephone Calls

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 radio and telephones on land, sea and in the air.

See pages 14 through 23 for the public correspondence (marine operator) channels.

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.

NOTICE

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.

Emergency Messages

and Distress Procedure

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 any event, communicate with the Coast Guard 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.

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 message.

Drop your anchor and call a friend or marina to bring the fuel you need or to give

you a tow.

Marine Emergency Signals

The three (3) spoken international emergency signals are:

The distress signal MAYDAY is used to indicate that a station is threatened

by grave and imminent danger and requests immediate assistance.

The urgency signal PAN is used when the safety of the vessel or person

is in jeopardy. (This signal is properly pronounced pahn.)

The safety signal SECURITE is used for messages about the safety of navigation or

important weather warnings. (This signal is properly pronounced see-cure-ee-tay.)

When using an international emergency signal, the appropriate

signal is to be spoken three (3) times prior to the message.

Emergency Messages

and Distress Procedure

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.

Marine Distress Procedure

Speak slowly — clearly — calmly.

1. Make sure your radio is On.

2. Select 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],” repeated three (3) times.

5. Say:

“MAYDAY (or “PAN” or “SECURITE”)

[your vessel name or call sign].

6. Tell where you are:

(what navigational aids or landmarks are nearby).

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 step 3 above.

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.

“Mayday — Mayday — Mayday”

“This is Corsair — Corsair — Corsair” [or “IL 1234 AB”], repeated three (3) times.

“Mayday Corsair (or IL 1234 AB)”

“Navy Pier bears 220 degrees magnetic — distance 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 hour”

“Corsair (or IL 1234 AB) is 26 ft sloop with blue hull and tan deck house”

“I will be listening on Channel 16”

“This is Corsair (or IL 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.

WARNING

This radio will generate a digital maritime distress and safety signal to help

facilitate search and rescue. This radio must be used only within

communication range of a shore based VHF station with a distress and safety

watch system. The range of the signal may vary, however, under normal

conditions should be approximately 20 nautical miles.

NOAA Weather Channels and Alert •

Monitoring the weather will probably be a frequent use of your radio. NOAA provides

continuous, around-the-clock broadcasts of the latest weather information. Taped

weather messages run every four (4) to six (6) minutes and are revised every two

(2) or three (3) hours, or as needed. The Coast Guard also announces weather and

other safety warnings on Channel 16 and DSC Channel 70. Smart boaters keep an

eye on safety and an ear to the radio — and never let the weather catch them

unaware.

NOAA Emergency Weather Alert

In the event of a major storm or other weather condition requiring vessels at sea

or on other bodies of water to be notified, NOAA broadcasts a 1050 Hz tone that

receivers such as your CobraMarine VHF radio can detect and warn you of a weather

alert condition. When the Weather Alert mode on your radio is On, this signal will

produce the weather alert alarm tone from the speaker and a “weather alert”

message on the LCD to signal that a weather alert is being broadcast.

The radio will automatically switch to Weather Radio mode.

Test

To test this system, NOAA broadcasts the 1050 Hz signal every Wednesday

sometime between 11 a.m. and 1 p.m. in each local time zone. Any receiver that can

detect the weather alert tone may use this feature to verify that this feature is

functioning properly.

Installation and Start-Up

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 suggests you purchase the best quality antenna, coaxial cable

and connectors you can. 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 10 ft (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 10 ft (3 m) away from the

antenna when the radio is transmitting.

Installation Requirements

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

be mounted at least 16.4 ft (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 ft (3 m) plus the 6.6 ft (2 m) height of an adult.

 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 ft (3 m) MPE radius during radio transmissions. The antenna must

be mounted so that its lowest point is at least 3.3 ft (1 m) vertically above

the heads of all persons during radio transmissions.

F80 Installation.qxp:QXP-1058720374.qxp 12/29/06 10:03 AM Page 31

32 English

Antenna Requirements

and Attachment

WARNING

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 9 ft (2,8 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 ENSURE THAT MPE LIMITS ARE HEEDED AND THAT

NO ONE IS WITHIN THE MPE RADIUS DURING TRANSMISSIONS.

Antenna Lead Attachment

Once the antenna is installed, the Coaxial Cable Lead can

be attached to the coaxial cable socket at the back of the

transceiver.

NOTICE

Attempting to transmit without an antenna attached

will damage your CobraMarine VHF radio.

External Devices

and Connections

33

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.

NMEA Communication Cable

Your CobraMarine Radio is set up with an NMEA communication port that allows the

radio to communicate with other electronic equipment such as a GPS Chartplotter,

Depth Sounder, Auto Pilot, DSC VHF Radio, Radar and Personal Computer with the

ability to display information. This capability allows for the operator to do Position

Polling and Position Requests directly from the radio. The NMEA input and output

leads are directed through the NMEA communication port.

External Speaker (Not Included)

An External Speaker can provide greater volume to hear messages than the speaker

in the transceiver.

To Install an External Speaker:

1. Connect the speaker positive (+) wire to the orange wire coming out of the

standard speaker/PA wire harness.

2. Connect the speaker negative (-) wire to the black/white wire coming out of the

standard speaker/PA wire harness.

Public Address Speaker (Not Included)

At times, it may be handy to address 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 Speaker:

1. Connect the PA speaker positive (+) wire to the rose red

wire coming out of the standard speaker/PA wire harness.

2. Connect the PA speaker negative (-) wire to the

black/white wire coming out of the standard speaker/PA

wire harness.

Global Positioning System (GPS) Device

(Not Included)

Cobra Electronics strongly recommends that you obtain and

connect a GPS device to your CobraMarine VHF radio. By

having a GPS connected, your position will

be continuously indicated on the LCD and, most importantly,

it will be included automatically in any DSC distress

message you may need to send. That will

take the “search” out of “search and rescue.”

To Install a GPS Device:

1. Install the GPS device in a convenient location according

to its manufacturer’s directions.

2. Bond the NMEA out negative (-) wire of your GPS to the

NMEA in negative (-) wire (green) of the MR F80

NMEA/IO interface cable.

3. Bond the NMEA out positive (+) wire of your GPS to the

NMEA in positive (+) wire (white) of the MR F80

NMEA/IO interface cable.

NOTE

When bonding the wires, make sure connections are

secure and properly insulated to prevent electrical

arching.

4. Connect the new combination cable to the GPS device

and to the back of the transceiver.

Special Features •

Rewind-Say-Again™ Feature

The MR F80 radio has a Cobra exclusive playback feature,

Rewind-Say-Again™. This feature allows you to replay the

last 20 seconds of an incoming audio transmission. It also

allows you to record call details including position

coordinates, call signs, registration numbers and store details

that will help authorities locate a distressed vessel.

Example 1:

When engine noise, music or conversation creates too much

noise to hear an inbound message clearly, press the Rewind-

Say-Again™ button to hear the message a second time. This

feature eliminates asking the sender to repeat the message.

Example 2:

When listening to an urgent distress of an excited caller with

confusing background noise, press the Rewind-Say-Again™

button to hear the message a second time and get lifesaving

information.

Operation of Rewind-Say-Again™

1. Press the Rewind button after the last inbound audio

transmission.

2. The radio automatically replays the last 20 seconds of the

previous audio transmission.

3. Respond to the caller normally, after the message is

replayed.

Introduction

Digital Select Calling (DSC)

Setup

Digital Select Calling (DSC) Setup •

Digital Selective Calling (DSC) uses digital signals to increase messaging range. This

provides the most reliable message delivery per watt of output power. Digital signals

are less susceptible to distortion from noise and atmospheric conditions than analog

signals.

DSC equipped radios also interface with GPS and automate many operations for

sending and receiving messages. This results in compact, accurate messages and

less airwave congestion.

Setup procedures for all DSC features use the Setup menu. Refer to page 40 for

information on entering and exiting the Setup menu.

User MMSI Number

The nine (9) digit MMSI number, similar to a telephone number, is a unique identifier

for a vessel. DSC incorporates this number into every message that is Sent (Tx) or

Received (Rx). Enter the MMSI number as soon as you receive your MMSI number

from the issuing agency listed on page 9.

NOTE

The radio does not operate in the DSC mode until an official MMSI number is

entered. An error tone will sound when attempting to operate in the DSC

mode without an MMSI number.

To Enter an MMSI Number:

NOTICE

Only one MMSI number change is allowed on this unit. To prevent constant

changes and potential errors, this MMSI number limitation is on all DSC

capable radios. If the MMSI number must be changed more than once, return

the radio to Cobra Electronics for resetting. Once the radio is reset, another

MMSI number may be entered and the radio can then be used in the DSC

mode.

Group MMSI Number

Nautical organizations like yacht clubs and regatta event

organizers can establish Group MMSI numbers. Messages

can then be automatically transmitted to all members of a

group without making individual calls.

The Group MMSI is established by modifying the MMSI

assigned to one (1) group member. To modify the MMSI

number, drop the last digit of the number and insert a zero

(0) at the beginning.

Example:

Member MMSI number 366123456 becomes Group MMSI

number 036612345.

Group MMSI numbers may be entered and changed any

time without resetting the radio. Each member of a group

must enter the group MMSI number in their radio to receive

group messages.
