Marine radio emergency procedure
This page has information on the marine radio distress/urgency procedure, including the distress channels/frequencies in Victoria.
An alarm signal is used to attract the attention of operators to the incoming message. It produces a two-toned warbling sound which can be easily distinguished, even in poor reception conditions.
Distress messages prefixed "MAYDAY" repeated three times are used only in grave and imminent danger.
Urgency messages prefixed "PAN PAN" repeated three times are used when you or your vessel are not in grave and imminent danger.
Safety signals prefixed "SECURITE" repeated three times (pronounced SAY-CURE-E-TAY) are used when a station wants to pass important information concerning safety such as navigational warnings or weather warnings.
