1. GETTING STARTED
1.1 Emergency Call (CH16)
CH16 is known as the Hail and Distress Channel. When an emergency occurs, be
sure the radio is on and set to CH16. Then do as follows:
Step 1 Press the Push-To-Talk (PTT) key of the microphone or handset and say
"Mayday, Mayday, Mayday. This is XXXXX, XXXXX, XXXXX" (your
vessel's name).
Step 2 Then repeat once: "Mayday, XXXXX" (your vessel's name).
Step 3 Report your position in latitude/longitude, or give a true or magnetic
bearing to a well-known landmark such as a navigation aid or geographic
feature such as an island or harbor entry.
Step 4 Report the nature of your distress (sinking, collision, aground, fire, piracy,
life-threatening injury, etc.).
Step 5 State the kind of assistance you desire (pumps, medical aid, etc.).
Step 6 Report the number of persons aboard and condition of them.
Step 7 Estimate the present seaworthiness and condition of your vessel.
Step 8 Give your vessel's description: length, design (power or sail), color and
other distinguishing marks.
Step 9 Say "over" to end the message. Release the PTT switch and listen.
Step 10 Optional: If there is no answer, repeat the above procedure. If there is still
no response, try another channel.
Note
The total transmission should be within one minute.
The FM-4800 has DSC Distress calling, which can send a distress call
digitally to all ships with compatible DSC radios. For more information, see
section 4 DIGITAL SELECTIVE CALLING.
If the emergency call is accidentally sent, please refer to "Sending a distress
cancel call" in paragraph 4.3.1.
1.2 How to Call another Channel (CH16 or CH9)
CH16 (or CH9, depending on area) should be used as the calling channel for initial
contact with another vessel. However, its primary purpose is for emergency
communications and should be monitored at all times when the radio is not using
other channels.
CH16 or CH9 is monitored by other vessels and Coast Guard stations in all
countries.
The use of CH16 or CH9 should be limited to making initial contact only. A call
4
should be within 1 minute, but can be repeated at a 2-minute interval.
Before contact another vessel, refer to the channel charts in the Appendix and select
a proper channel (working channel) for use after initial contact. Monitor the proposed
channel to ensure you won't be interrupting other traffic and then go back to CH16 to
make your initial call.
When CH16 is clear, state the name of the vessel you wish to call and the "this is"
followed by the name of your vessel and your vessel call sign. When the other vessel
returns your call, immediately request another channel by saying "go to", the
number of the other channel, and "over". Then switch to the new channel. When the
new channel is not busy, call the vessel.
After a transmission, say "over", and release the PTT switch on the microphone.
When all communication with the vessel is completed, end the last transmission by
stating your call sign and the word "out". Note that you do not need to state your call
sign with each transmission, only at the beginning and end of the contact.
Remember to return to CH16 when not using another channel. Some radios
automatically monitor CH16 even when set to other channels or when scanning.
1.3 Channels 13 and 67 (USA Channel Group only)
Channel 13 is used at docks and bridges and by vessels maneuvering in port.
Messages on this channel must concern navigation only, such as meeting and
passing in restricted waters.
Channel 67 is used for navigational traffic between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your radio is
programmed to automatically reduce power to this limit on these channels. However,
in emergency situations it may be temporarily use a higher power. See section 2
CONTROLS for how to temporarily override the low-power limit on these two
channels.

4. DIGITAL SELECTIVE CALLING
4.1 General
Digital Selective Calling (DSC) is a semi-automated method to establish a radio call.
DSC has been designated by the International Maritime Organization (IMO) as an
international standard for establishing VHF, MF and HF radio calls. It has also been
designated as a part of the Global Maritime Distress and Safety System (GMDSS).
DSC replaces listening watches on distress frequencies and is used to broadcast
routine and urgent maritime safety information broadcasts.
This system allows mariners to instantly transmit a distress call with GNSS position
to the Coast Guard and other vessels within the range of the transmission. DSC also
