EPIRB / PLB Programming ServiceProgramming service requires that we have the vessel's MMSI number and country of registration. The vessel name may also be programmed into the unit; please provide this if desired. Some countries have additional or alternative requirements; we will contact you if more information is necessary. International agreements dictate that EPIRBs must be programmed for the country under the flag of which a vessel sails or of which the vessel owner is a resident in order to register the beacon with that country's SAR authorities.This product may not be returned to the original point of purchase.
