What the result means: This is a non-emergency inspection guide, not an activation or rescue procedure. Never activate distress transmission as a test. Follow the complete exact manual for any scheduled self-test; tests have timing and lifetime limits. Do not open, reprogram or certify the beacon yourself. In real danger, follow its official emergency instructions.
Identify which test was recorded
A basic self-test does not acquire a GPS location; the separate GPS/GNSS test does. Record the test type, date, complete LED sequence and, on PLB-425 only, the exact display result. Do not read one initial green flash as the final result. A recorded pass does not certify a future rescue outcome.

Follow the complete exact manual for any scheduled self-test; tests have timing and lifetime limits. Do not open, reprogram or certify the beacon yourself. In real danger, follow its official emergency instructions.
Check registration identity privately
Compare the beacon’s Hex ID/UIN with your existing national registration confirmation and check that owner/emergency-contact details are current. A successful self-test does not verify those records. Use the relevant official authority for corrections; country programming is a separate service matter. Keep identifiers and contacts out of public reports.

Follow the complete exact manual for any scheduled self-test; tests have timing and lifetime limits. Do not open, reprogram or certify the beacon yourself. In real danger, follow its official emergency instructions.
Refer physical damage or persistent failure
Inspect the case without dismantling it. The manual directs cracks to ACR evaluation because moisture can cause malfunction or false activation. Preserve photographs and an existing failed-test result for ACR or an authorized service center. Follow their shipping instructions; this page does not declare a damaged beacon fit for use.
