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.
