Ocean Signal rescueME PLB1 · 912S-01260 Issue 02.23 · 2025-04-17. These pages cover PLB1, PLB3, EPIRB1 and EPIRB3 / EPIRB1 Pro / EPIRB2 Pro / EPIRB3 Pro / E100 / E100G only. Pro versions and country protocols require their own documentation. A country filter does not confirm approval or registration.
How it connects
On PLB1, keep the antenna rewind mechanism distinct from PLB3 controls: the manual says not to push the antenna back into the case. In an existing record, three quick green flashes mean a GPS fix; five quick flashes mark a 406 MHz transmission, not a rescue acknowledgement. Do not activate it to reproduce this. Basic beacon tests, GNSS tests and rescue acknowledgements answer different questions. Preserve existing results and their time; a successful test does not verify the owner registration. This is a non-emergency inspection. Do not activate distress transmission, open the case or start extra tests for this guide. In real danger, follow the exact official emergency instructions.
