Abstract

PURPOSE:To decrease the energy consumption at a waiting time by dividing a slave station reception device into the four parts of a reception signal processing part, processing parts and a loud speaking/amplifying part and operating by stages the reception of a prescribed electric wave, the reception of a signal, an incoming to a self station and the driving of a loud speaking amplifier. CONSTITUTION:A power source is always supplied to a receiver 2 and when a reception wave is received, the receiver 2 outputs a squelch-on signal and operates a signal processing part 6 with this signal. When a frame synchronizing signal is received preceding to data encoded by a part in which a digital signal received from a master station is decoded, the signal processing part causes a processing part 10 to be an operating condition. For the both of the signal processing part and the processing part, the low energy consumption mode of a standby or a sleep condition is obtained at the waiting time. A processing part 11 executes collation with a self station code from reception data 9, password collation and the output of a control signal 7, etc. The control signal turns on the power source of a loud speaking amplifying part 4 and a sound signal 3 is loudly spoken from a speaker 5. Thus, the operation even of the processing part with the unnecessary electric wave can be decreased and an operation guarantee time can be extended at a service interrupting time.
