摘要 The mobile telecommunication transmission apparatus (1) involves a method for release of its signal function and a control unit (5) facilitating location of the apparatus in the event of loss or theft. An activation signal production unit (10) is provided and a transmission unit (15) radiates the activation signal at least at one first predetermined time point with a predetermined power to a control unit (5). A receiver unit (20) can receive a reply signal from the control unit. An evaluation unit (25) checks whether the reply signal has been received within a first predetermined period after transmission of the activation signal . The evaluation unit releases a signal function to the mobile telecommunication transmission apparatus when within the first predetermined period no reply signal has been received.
