Operating Your Radio VHF Marine Radio Protocols Introduction

Maintenance

Very little maintenance is required to keep your Cobra Marine VHF radio
in good operating condition:
Keep the radio and charger clean by wiping with a soft cloth and mild detergent.
n
Do not use solvents or harsh or abrasive cleaners, which could damage the case or
scratch the LCD screen.
If the radio is exposed to salt water, wipe with a soft, moist cloth at least once a day
n
to prevent buildup of salt deposits, which could interfere with button operation.
If the radio will be stored for a long period, such as over the winter,
n
remove the batteries from the battery tray and store them in a separate
package. This is especially important if you are using alkaline batteries.

Procedures
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. If there is no answer,
switch to 3 watts and call again. You have the ability to go up to 6 watts of output power
to increase your calling distance. Remember, the lower wattage outputs will conserve your
battery and minimize interference to other users.
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) 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 (if available), vessel name and the
state registration number, at both the beginning and at the end of the message.
