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 .
