Abstract (en)

[origin: EP0453957A2] The invention relates to a remote-controlled home electronics device (6) equipped with a monitoring circuit (3, 4) for the condition of the battery of the remote-control device (1). As the battery state is thus monitored by the receiving end, the extra load to the battery caused by the monitoring process is avoided. The transmitting circuit of the remote-control device (1) is designed so that the signal form, e.g. the durations and/or the spaces of the transmitted control pulses will essentially change when the battery is weakening. <IMAGE>
