406 MHz EPIRBs and Personal Locator Beacons


When performing EPIRB and PLB tests, always use the test mode on the beacon. Doing so, the beacon will radiate a single burst, which is specially coded to be ignored by the COSPAS-SARSAT system.


If the beacon is accidentally activated in the emergency transmission mode, the test box will display WARNING ALARM. Then, the beacon should be turned off at once and the false alert reported to the nearest coast guard station or Search and Rescue centre.
