- Recognise the distress threshold early and choose Mayday when a vessel or person is in grave and imminent danger and immediate assistance is required.
- Distinguish the distress alert, voice distress call and distress message, then use the identity sequence without dropping the second MAYDAY or the registered identifiers.
- Complete the immediate sequence after a DSC distress alert instead of waiting silently for the digital alert to solve the emergency.
