Wirelessly remote-controllable device of entertainment electronics

摘要

The remote-control transmitter (3) of a wirelessly remote-controllable device (1) of entertainment electronics additionally contains a monitoring signal generator (14), connected to the input of the carrier wave transmitting source (6), which, in the switched-on state, generates pulses for monitoring the space (8) between the remote-control transmitter and the set housing. These monitoring pulses are received in the receiver housing by means of the receive transducer (11) for the remote-control signal transmission and evaluated in an evaluating circuit (26) which can be switched on and off, for example from the remote control transmitter. In the event of a disturbance of the monitored space (8), the evaluating circuit triggers an alarm signal via an alarm generator circuit (35) on a reproduction device (36, 39) of the set. <IMAGE>
