What information is transmitted by a 406 MHz EPIRB alert?
They transmit a digital identification code on 406 MHz and a low-power “homing” signal on 121.5 MHz. The 406 MHz EPIRBs are divided into two categories: Category I EPIRBs are automatically activated. The automatic activation is triggered when the EPIRB is released from its bracket.

Which vessel is required to carry a category I 406 MHz EPIRB?
Commercial fishing indus- try vessels
Commercial fishing indus- try vessels operating on the high seas (beyond the three mile territorial sea line) or beyond three miles from the coastline of the Great Lakes (unless exempted) must carry a 406 MHz EPIRB.
How do you test a 406 MHz ELT?
Ensure the 406 MHz transmitter is connected to a test set if possible. Activate the ELT (use the remote switch if installed), and determine if the system is radiating a strong 406 MHz signal. Ensure the system is reset if necessary. If equipped with a water-activated circuit, connect the ELT to a test set if possible.
Where can I find the 406 MHz frequency?
The 406 MHz frequency is a worldwide dedicated emergency frequency that is detected by a network of satellites called the Cospas-Sarsat system. This satellite system was established by, and continues to be supported by, its primary benefactors – the USA, Russia, Canada and France.
How does a 406 MHz rescue beacon work?
Some 406 MHz beacons can transmit GPS positions with an accuracy of 100 meters. Geostationary satellites provide instantaneous locating! The bottom line is this. With a 406 beacon your distress signal will be received from anywhere on the planet, located accurately and quickly, and rescue forces will know who and what to look for.
