What emergency phase would be initiated upon receipt of a registered but unlocated 406 MHz alert?

Explanation:
When a registered 406 MHz beacon is detected but its exact location isn’t known, the situation is treated as a distress scenario. A 406 MHz beacon is an emergency signal intended to summon immediate help because lives may be at risk, and the fact that the beacon is registered only helps responders identify the owner and follow up, not eliminate the urgency. Without a location, responders must initiate a search to find the beacon and assess the danger, which is why this triggers the distress phase. An alert phase would apply to a suspected or unconfirmed emergency, not an active distress signal. An urgent phase is for situations needing assistance but without immediate life-threatening risk, and safety is used when there’s no threat to life. So, receiving a registered but unlocated 406 MHz distress alert calls for immediate SAR action to locate and assist, making distress the appropriate phase.
