Owner’s Manual
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 seven 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 select for your area.

Important Safety Information
Introduction
Introduction
The following WARNINGS and CAUTIONS will make you aware of RF exposure
hazards and how to assure you operate the radio within the FCC RF exposure
limits established for it.
Important Safety Information
•
Before installing and using your CobraMarine VHF radio,
please read these general precautions and warnings.
WARNINGS
Warning And Caution Statements
Your radio generates electromagnetic RF (radio frequency) energy when
it is transmitting. To insure 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 30 in the
antenna requirements section for further information.
To make the most of this radio, it must be installed and used properly.

installing and using it. Special attention must be paid to the WARNING
and CAUTION statements in this manual.
WARNING
Statements identify conditions that could result in personal injury or loss of life.
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.
CAUTION
Statements identify conditions that could cause damage to the radio
or other equipment.
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.

Recommendations For
Marine Communication
FCC Information
Introduction
VHF Marine Radio Protocols
FCC LICENSING INFORMATION
CAUTIONS
•
CobraMarine VHF radios comply with the FCC (Federal Communication Commission)
requirements that regulate the Maritime Radio Service.
AVOID using or storing the radio at temperatures below -4°F (-20°C) or
above 140°F (60°C).
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.
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.
The transceiver is capable of Class-D (Digital Selective Calling) operation in
accordance with CFR Part 47, Section 80,225.
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.
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 (1) key.
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.
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.
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
Communications Commission) rules and make it illegal to use.
FCC license forms and applications for ship and land stations can be downloaded
the FCC at 888-225-5322.
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.
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
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.
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.
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.

VHF Marine Radio Protocols
VHF Marine Radio Protocols
User Responsibility And Operating Locations
Limits On Calling
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.
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
NOTE
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.
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.
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.
FCC Warnings: Replacement or substitution of transistors, regular diodes,
Prohibited Communications
You MUST NOT transmit:
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.
I
False distress or emergency messages.
I
Messages containing obscene, indecent, or profane words or meaning.
VHF Marine Radio Procedures
•
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.
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.
I
When you are on land.
Power
Voice Calling
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.
•
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.
Calling Coast Stations
Call a coast station on its assigned channel. You may use Channel 16
when you do not know the assigned channel.
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.
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.
I
When the channel is quiet, press the Talk button and call the ship 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].”
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.
I
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.

Maritime Mobile
Service Identity (MMSI)
Digital Selective Calling (DSC)
VHF Marine Radio Protocols
For Example
VHF Marine Radio Protocols
Maritime Mobile Service Identity (MMSI)
•
The vessel Corsair calling the vessel Vagabond:
The MMSI Number Is Available In The U.S.A. From Any Of Two (2) Sources:
I
Corsair: “Vagabond, this is Corsair (station license number call sign).”
Vagabond: “Corsair, this is Vagabond. Over.”
I
Corsair: “Vagabond go to working Channel 68. Over.”
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
maritime mobile service identity (MMSI) number. See page 41 for instructions
on how to enter it.
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).”
In Canada, Contact:
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.
I
Industry Canada Spectrum Management Office (only available on the Internet):
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.
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.
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.
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).
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.

Emergency Messages
And Distress Procedure
Radiotelephone Calls
VHF Marine Radio Protocols
VHF Marine Radio Protocols
Radiotelephone Calls
Marine Emergency Signals
The three (3) spoken international emergency signals are:
MAYDAY
•
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 62 through 73 for the public correspondence (marine operator) channels.
The distress signal MAYDAY is used to indicate that a station is threatened
by grave and imminent danger and requests immediate assistance.
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.
PAN
The urgency signal PAN is used when the safety of the vessel or person
is in jeopardy. (This signal is properly pronounced pahn.)
CAUTION
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.
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.
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.
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.
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.
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.
In any event, do 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 marine to bring the fuel you need or to give
you a tow.

VHF Marine Radio Protocols
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.
Marine Distress Procedure
Speak slowly — clearly — calmly.
1. Make sure your radio is On.
For Example
“Mayday — Mayday — Mayday”
2. Select VHF Channel 16.
“This is Corsair — Corsair — Corsair” [or “Illinois 1234 AB” three (3) times]
“Mayday Corsair (or Illinois 1234 AB)”
3. Press Talk button and say:
“MAYDAY — MAYDAY — MAYDAY.”
(Or “PAN — PAN — PAN,”
or “SECURITE — SECURITE — SECURITE.”)
“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”
4. Say:
“THIS IS [your vessel name or call sign].”
1
“Estimate we will remain afloat one-half ( ⁄2) hour”
5. Say:
“Corsair (or Illinois 1234 AB) is 26 foot sloop with blue hull and tan deck house”
“MAYDAY (or “PAN” or “SECURITE”)
[your vessel name or call sign].
“I will be listening on Channel 16”
“This is Corsair (or Illinois 1234 AB)”
“Over”
6. Tell where you are:
(what navigational aids or landmarks are near).
7. State the nature of your distress.
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.
8. State the kind of assistance needed.
Marine Distress Procedure – DSC
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).
•
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.
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.
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.

Antenna Requirements And Attachment

Radio Operator Requirements
Antenna 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 9' (2.8 m) horizontally from the
base of the antenna during transmissions.
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.
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.
WARNING
Antenna Lead Attachment
Once the antenna is installed, the Coaxial Cable Lead can
be attached to the socket at the back of the transceiver.
Coaxial Cable Socket
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
CAUTION
To avoid health hazards from excessive exposure to RF energy, FCC OET
Bulletin 65 establishes an MPE radius of 10' (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' (3 m) away from the
antenna when the radio is transmitting.
Attempting to transmit without an antenna attached
will damage your CobraMarine VHF radio.
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.

Global Positioning System (GPS) Device (Not Included)
•
Cobra® 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.”
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.

Transmit Power Output
•
Your radio can Transmit selectively at one (1) or 25 watts of power. Cobra®
suggests you maintain the low power setting for short-range communications
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 one (1) watt.
Transmit mode gives you the ability to communicate with safety services, other
vessels, and shore stations. When you use this capability, be sure to follow the
procedures and to observe the courtesies that govern its use so everyone benefits.
(The tables on pages 66 through 73 will help you select the proper channels.)
Before pressing the Talk button to transmit a message, you should select the
appropriate channel and transmit power output.
To Toggle Between The High And Low Power Modes:
High/Low Power Button
1. Press the High/Low Power button.

Some channels are restricted to use at a maximum of
one (1) watt. Your radio will automatically set the power
to Low Power mode when you select those channels.
While using the U.S.A. channel map, if, in an emergency,
you need to increase the output power on Channel 13 and

DSC Set-Up
•
Digital selective calling — DSC — employs digital RF signals which tend to carry
further and be less susceptible to distortion from noise and atmospheric conditions
than analog ones. The result is greater range and more reliable message delivery
per watt of output power.
User MMSI IDꢀEntry
But, that is not the only advantage of DSC equipped radios. Those radios are set up
to interface with GPS and to automate many of the operations involved in sending
and receiving messages. That results in more compact and accurate messages and
less congestion of the airwaves.
The price of these benefits to the user is the time it takes to do the required set-up
to make the DSC features work. A little time spent when your radio is new will pay
dividends over its life.
These procedures use the Settings menu. Refer to page 38 for information on
entering and exiting the Settings menu.
5. Repeat steps 3 and 4 until all nine (9) digits of your
MMSI number are entered.
NOTE
Press the High/Low Power button to backspace
and erase the last selected number.
User MMSI Number
6. Check that you have entered the number correctly. The
unit will ask you to re-enter your number to confirm.
7. Press and hold the Call/Set button to return to the
Settings menu.
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.
Error Message
If You Incorrectly Enter Your MMSI Number
NOTE
You can repeat steps 1 through 7 to correct it. HOWEVER,
YOU CAN DO THIS ONLY ONCE! A third attempt to enter
an MMSI number will result in an error message as shown.
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.
Pressing the Call/Set button from the error message
will return the radio to the Settings menu.
Call/Set Button
NOTE
An MMSI number can only be entered one time. To create a new MMSI
number, the unit must be reset by the dealer.
Once the error message appears, the radio will still
operate in all non-DSC modes. But you will have to
return the radio to Cobra® Electronics (see product
service on page 73 for details) for reset before you
can enter your MMSI number and use the radio in
DSC mode.
Because the MMSI number is so important to DSC
operation, this limitation is imposed on all DSC capable
radios to prevent constant changes and the potential
introduction of errors in the process. If, for any reason,
it is necessary to change the MMSI number in the radio
®
more than once, you can return it to Cobra Electronics
for reset.

NOTE
Channel
Number
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 A3).

NOTA
Muchos de los canales de números simples, como 01, 02 y 03, transmiten
y reciben en diferentes frecuencias. A esto se le llama operación dúplex. El
resto de los canales de números simples y todos los canales A, como 01A,
03A y 04A, transmiten y reciben en una sola frecuencia, a la que se le llama
operación simple (simplex). Su radio se ajusta automáticamente a estas
condiciones. Cuando esté en operación simple, el icono A aparecerá en la
pantalla de cristal líquido (vea la ilustración de la página A3).
NOTA
Todos los canales vienen programados previamente de fábrica conforme
a los reglamentos internacionales y a los de la FCC (EE. UU) e Industry Canada
(Canadá). No pueden ser alterados por el usuario, así como tampoco pueden
cambiarse los modos de operación entre simple y dúplex.
