Abstract

System for tyverisikring av elektronisk utstyr (27) , der systemet omfatter en sender (22), fortrinnsvis med en posisjon som skiller seg fra posisjonen til det elektroniske utstyret, hvilken sender (22) er innrettet til å generere et signal omfattende en kode innrettet til å overfares til det elektroniske utstyret, og der utstyret (27) er forsynt med en kontrollinnretning (21) innrettet til å motta og gjenkjenne den utsendte koden og på bakgrunn av den mottatte koden tillate bruk av utstyret. Den genererte koden har en varighet som strekker seg over en lengre tids- periode, fortrinnsvis over et halvt døgn, og kontrollinnretningen (21) er innrettet til å avbryte utstyrets funksjon ved uteblivelse av..det koden.The system for theft protection of electronic equipment (27), wherein the system comprises a transmitter (22), preferably with a position different from the position of the electronic equipment, which transmitter (22) is arranged to generate a signal comprising a code adapted to to be transmitted to the electronic equipment, and wherein the equipment (27) is provided with a control device (21) adapted to receive and recognize the transmitted code and, on the basis of the received code, allow the use of the equipment. The generated code has a duration which extends over a longer period of time, preferably over half a day, and the control device (21) is arranged to interrupt the operation of the equipment in the absence of the code.
