To Call Another Vessel Or A Shore Installation Such As A Lock Or Bridge Tender:
n
Make sure your radio is On.
n
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.
n
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].”
n
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.

Procedures
Canadian Ship Station License
You need a Radio Operator’s Certificate if your vessel is operated in Canadian waters.

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.
