I am proceeding to your assistance
Action by Station Acknowledging Receipt of a Distress Message
1. Forward information immediately to the appropriate Coast Guard or search and rescue agencies or organizations.
2. Continue to guard the frequency on which the distress message was received and, if possible, any other frequency that may be used by the station in distress,
3. Notify any station with direction-finding or radar facilities which may be of assistance.
4. Cease all transmissions that may interfere with the distress traffic.
Action by Other Stations Hearing a Distress Message
1. Continue to guard the frequency on which the distress message was received and, if possible, establish a continuous watch on appropriate distress and emergency frequencies.
2. Notify any station with direction-finding or radar facilities and request assistance, unless it is known that this action has been or will be taken by the station acknowledging receipt of the distress message.
3. Cease all transmissions that may interfere with the distress traffic.
Distress Traffic
Distress traffic consists of all transmissions relative to the immediate assistance required by the station in distress.
Essentially, all transmissions made after the initial distress call are considered as distress traffic. In distress traffic, the distress signal MAYDAY, spoken once, shall precede all transmissions. This procedure is intended to alert stations unaware of the initial distress call, and now monitoring the distress channel, that traffic heard relates to a distress situation.
Any station in the Maritime Mobile Service that has knowledge of distress traffic and cannot itself assist the station in distress shall, nevertheless, follow such traffic until it is evident that assistance is being provided.
Until a message is received indicating that normal working may be resumed (there has been a cancellation of distress), all stations that are aware of distress traffic but are not taking part in it are forbidden to transmit on the frequencies being used for distress traffic.
3.2.4 Acknowledge Response
Message transmitted by the vessel in distress conforming the Assistance Information Message has been understood. (example);
