9Authorisation regimeRegistration of 406 MHz PLB is mandatory.The PLB shall be coded with the owners identification and the country code according to the registration. (The country code is 269 for residents of Switzerland and the Principality of Liechtenstein)
PLB have to be registered at the COSPAS-SARSAT Database (http://www.cospas-sarsat.int/en/774-registering-your-beacon).

Use of PLB:
Switzerland: License exempt.
Liechtenstein: General authorisation.

15RemarksPLB may be used in civil aviation and on maritime pleasure boats.Pilots may use a PLB as an alternative to ELT when an ELT is not mandatory. A PLB can be carried additionally to a mandatory ELT. (For ELT refer to [RIR0104-01])
On condition that the PLB is programmed with MMSI (Maritime Mobile Station Identity), it may be operated as EPIRB (Emergency Position Indicating Radio Beacon) on pleasure boats, navigating under Swiss flag or the flag of the Principality of Liechtenstein. (For EPIRB refer to [RIR0601-16])
