Abstract

PURPOSE:To bring all radio stations into control rapidly and securely while saving labor and utilizing radio waves in a radio communication system for selective calling which consists of one base station and mobile stations, when control over communication from the base station is required for an emergency situation. CONSTITUTION:With a control switch S2, a control circuit CONT2 operates to output a signal ([(A) transmission (2)]in Fig.), increasing gradually in interval of time, to a control circuit CONT1, which operates a selective call signal generating circuit SC at every interval of time to drive a radio telephone set TRX, sending a control signal from an antenna. Through the operation of a switch S3, both the CONT2 and CONT1 are operated and a tape deck TAPE is also driven to transmit the control signal firstly and a message successively automatically.
