Abstract

PURPOSE:To attain whether or not each individual station can receive a transmission signal from a master station normally by allowing the individual station to send a reply signal in a prescribed timing after the reception of a signal to an outdoor station in a weak radio wave or a small power, allowing the outdoor station to detect the presence or absence of the reply signal and sending the result of detection to the master station. CONSTITUTION:A transmitter 7a of an individual station 7 receiving a broadcast from a master station 1 sends a reply signal to an outdoor station 6 in a prescribed timing set in its own station in a weak radio wave or a small power. A reply signal detection section 6a-1 detects the presence or absence of the reply signal from each individual station 7 for a prescribed period only. Then the transmitter 4a of the outdoor station 6 sends the result of detection of the reply signal from each individual station 7 to the master station 1. As a result, the master station 1 can recognize the transmission signal of the master station normally. Thus, the confirmation of reply whether or not each individual station can receive the transmission signal of the master station normally is attained in the range of the existing law.
