Abstract

PURPOSE:To attain battery saving with excellent transmission efficiency by turning on/off elastically a power supply of plural reception terminals based on command information from a control station in a system transmitting data from the control station to a single or plural reception terminal devices by employing radio. CONSTITUTION:A transmission format transmitted from the control station consists of a synchronizing code SC, information code section P1 and an information section P2. Each terminal device allows the power supply of the receiver to turn on between the information codes ''00100'' and ''00200''. If a code or an own device number of a data received for itself in the information code P1, however, is not designated to an information code IC or a terminal device number TN, the power supply for the receiver is turned off for 60sec. from a battery saving period TBC ''00060'', thereby attaining the battery saving.
