Abstract

PURPOSE:To save the power and to increase the reliability of the control system, by generating the control signal only to the wired terminal, stopping the delivery of electromagnetic waves at waiting and performing loop check of the control system. CONSTITUTION:The priod of operation of the transmitter 22 of the wired terminal is controlled with the logic control circuit 30 so that no electromagnetic waves can be transmitted at waiting and the detector 35 detecting the control signal f2 developed by itself is provided and the loop check is performed by detecting that the control signal f2 is returned via the mobile terminal through the feeding of a part of the output of the reveiver 12 at the mobile terminal to the delivery signal switch 9. a, mobile terminal unit b, wired terminal unit 15, 30 logic control circit
