FCC ENFORCEMENT ADVISORY
Enforcement Bureau Reminds Users of all Emergency Locator Beacons
About Their Proper Use and Registration
What are Emergency Beacons and How Are They Used?
Beacons (EPIRBs) for maritime use, Emergency Locator Transmitters (ELTs) for aviation use, and Personal Locator Beacons
(PLBs) for land-based use. All emergency beacons operating on frequency 406 MHz can be tracked by satellites and must be
registered with the National Oceanic and Atmospheric Administration (NOAA) for Search and Rescue Satellite Aided Tracking
(SARSAT). As discussed below, false alarms from or failures to register emergency beacons may result in substantial monetary
penalties (up to $112,500 for any single act).
Emergency Position Indicating Radio Beacons (EPIRBs)
MHz may be manufactured, imported or sold in the United States.1 A separate license is not required to operate an EPIRB. The
frequency 406 MHz has been designated internationally for use only for distress signals. The 406 MHz EPIRBs are divided into
two categories. Category I EPIRBs are activated either manually or automatically. The automatic activation is triggered when
the EPIRB is released from its bracket. Category II EPIRBs are activated manually.
Detected by Satellites.A 406 MHz EPIRB signal can be instantly detected by satellites, which allows a search and
rescue team to accurately locate the EPIRB and identify the vessel anywhere in the world. Even a brief
inadvertent activation on frequency 406 MHz can generate a false alert and is a violation of FCC Rules, thereby
subjecting the operator to potential monetary penalties up to $112,500. Operators should take every precaution to
avoid such activations because activations do not create an audible tone.
Must Be Registered.The FCC requires that all 406 MHz EPIRBs be registered with NOAA.2 Failure to register an
EPIRB may subject its owner to monetary penalties up to $112,500. More importantly, registration will help rescue
forces find a vessel faster in an emergency and allows the operator to contribute to the safety of others by not
needlessly occupying search and rescue resources that may be needed in an actual emergency.
Emergency Locator Transmitters (ELTs)
emergency beacons developed and most U.S. civil aircraft are required to carry them. ELTs were originally intended for use on
the frequency 121.5 MHz to alert aircraft flying overhead. Obviously, a major limitation to the early ELTs is that another aircraft

must be within range and listening to frequency 121.5 MHz to receive the signal. While ELTs operating on frequency 121.5 MHz
are still permitted in the United States, ELTs operating on frequency 406 MHz are also available and encouraged.4 A separate
license is not required to operate an ELT.
Detected by Satellites.406 MHz ELT ELTs have the same advantages as 406 MHz EPIRBS: they can be instantly
detected by satellites, which allow a search and rescue team to accurately locate the 406 MHz ELT anywhere in the
world. ELTs can also be activated manually or automatically. Inadvertent and non-emergency-related activations violate
FCC Rules and may subject the operator to monetary penalties up to $112,500.
Must Be Registered.Also like 406 MHz EPIRBs, 406 MHZ ELTs must be registered with NOAA.5 Failure to register
can result in monetary penalties up to $112,500.
Personal Locator Beacons (PLBs)
carried by an individual instead of on a boat or aircraft. Also, like EPIRBs or ELTs, the FCC authorizes PLBs to be used only for
distress and safety communications.6 PLBs are licensed by rule, and an individual license is not required.
Detected by Satellite.PLBs can only be activated manually and operate exclusively on frequency 406 MHz.7 Like 406
MHz EPIRBs and ELTs, they can be instantly detected by satellites. Inadvertent and non-emergency-related activations
are a violation of FCC Rules and may subject the operator to monetary penalties up to $112,500.
Must Be Registered.The FCC requires that PLBs also be registered with NOAA.8 Failure to register can result in
monetary penalties up to $112,500.
