Abstract

Una unidad de comunicación móvil, caracterizada porquecomprende: - una antena removible y un conmutador que está adaptado para cortar la provisión de la energía eléctrica a por lo menos la parte emisora en radio frecuencia de la unidad al removerse la antena, o: - una antena removible, y una tapa presionada por resorte, que está adaptada para recubrir a modo de escudo o pantalla una abertura dejada en la unidad automáticamente al removerse la antena, o: - un decodificador que está conectado a la salida de un detector y que está adaptado para decodificar y validar un mensaje recibido junto con una señal de corte de la energía eléctrica antes que la energía eléctrica suministrada a por lo menos la parte emisora en radio frecuencia de la unidad, sea desconectada; o - un medio de control, adaptado para reconocer un predeterminado código ingresado en el teclado de la unidad y, en respuesta a ello, para desconectar la energía eléctrica suministrada a por lo menos la parte emisora en radio frecuencia, de la unidad.A mobile communication unit, characterized in that it comprises: - a removable antenna and a switch that is adapted to cut off the supply of electrical energy to at least the radio frequency emitting part of the unit when the antenna is removed, or: - an antenna removable, and a spring-loaded cover, which is adapted to cover as an shield or screen an opening left in the unit automatically when the antenna is removed, or: - a decoder that is connected to the output of a detector and is adapted to decode and validate a received message together with an electrical power cut signal before the electrical power supplied to at least the radio frequency emitting part of the unit is disconnected; or - a control means, adapted to recognize a predetermined code entered in the keyboard of the unit and, in response thereto, to disconnect the electrical energy supplied to at least the radio frequency emitting part of the unit.
