GME GX294 - Manual (Page 10)

Normal Operating Procedure
Most calls to other vessel or stations are
made on channel 88. After listening to ensure
channel 88 is clear, call the other station,
repeating both call signs three times.
e.g.“Coast Guard, Coast Guard,Coast Guard,
This is –
Seaspray, Seaspray, Seaspray,
Over.”
Once contact has been established, move
straight to another channel (e.g. 91 or 94) to
continue your conversation leaving channel 88
clear for emergencies or further calls. Don’t
forget to return to channel 88 or select dual
watch when you have finished otherwise you
may miss other calls meant for you.
Emergency Procedures
All emergency calls should be made on
channel 88. There are three main types of
Emergency call.
1. “MAYDAY, MAYDAY, MAYDAY”
This call should be used where you are in
grave and imminent danger and require
immediate assistance. You should call
MAYDAY three times followed by your vessels
name or callsign three times. Then state your
position, a brief description of your vessel, the
nature of the emergency, the number of
people on board and their condition. If you
hear no reply, repeat the call at short intervals
because someone may be able to hear you
but you might not be able to receive their
reply.
After contact has been made, follow any
instructions given to you.
2. “PAN PAN, PAN PAN, PAN PAN”
Use this call when an emergency situation
exists but there is no immediate danger. The
call should be made the same way as the
MAYDAY call. If you hear no reply repeat the
call at regular intervals.
3. “SECURITE, SECURITE, SECURITE”
(Pronounced Say-cure-e-tay).
This call is used to warn other shipping of
dangers or hazards e.g. bad weather,
container adrift etc. The call may be made to a
local monitoring station or to all ships in the
area.
