Usage Notes

This message is broadcast as a non-addressed message, to reduce the message size, and to avoid issues from a relocated RSI to a different MMSI.
The “Subsequent Changeover” field is optional and unlimited per Project 25. In order to limit message size to 5 slots, the count of instructions is limited to 35 per message
