Abstract

PURPOSE: To make an identification and detection capable for a state of operation of the load being viewed from a transmitter side, by a provision, in the transmitter, of a confirmation signal receiving circuit, that receives a confirmation signal of reception confirming signal generator circuit output in the receiver, and an indicating method, that is driven by an output from said confirmation signal receiving circuit.
CONSTITUTION: Constitution of a reception confirming signal generator circuit 7 comprises an oscillating unit 29a, 29b of frequency f1, f2 and an encoder 28. An output of the decoder 28 for reception is inputted through a channel control 27, with a received signal identified in what state of control, and this identified result will be returned as the confirmation signal. Said confirmation signal is inputted to an indicating method 10, with a state of operation of the load identified and detected from at the side of transmitter
