STEP ONE - REGISTERING YOUR BEACON
Why is registration important?
As the owner of this 406 MHz beacon, it is mandatory that you register 
it with the PLB national authority of your country: It is the law. Please 
note that all 406 MHz beacons are required to have their registration 
updated every two years by the owner. 
 
 
HOW REGISTRATION WORKS: 
 
All 406 MHz beacons transmit a Unique Identifier Number (UIN) when 
activated. This UIN is programmed into the beacon based on the 
country in which the beacon is registered, thus authorities are able to 
determine which country
’s database will have your registration
information. SAR forces will have information as to who you are as the 
owner of the beacon, the name and type of vessel that you have (if 
applicable), your address, and who to contact that might know of your 
current situation - but only if your beacon has been properly registered. 
Valuable search and rescue resources are wasted every year 
responding to false alerts, and registering your beacon helps to resolve 
this quickly. 
Your personalized ID code 
programmed inside each beacon is 
transmitted to Search and Rescue 
(SAR). SAR forces use this code to pull 
up your registration to find out valuable 
information about who needs help. 
YOUR RESCUE WILL
BE DELAYED IF YOUR 
BEACON ISN
’T PROPERLY
REGISTERED!
