PROBLEM TO BE SOLVED: To solve a problem of troublesome operation of an operator who needs to perform an addressing call and a clearing operation for each sending of intelligence when two or more intelligence medias are transmitted continuously in the simulcast wireless system. SOLUTION: Each intelligence media is once stored and held in a key station operation console, while multiple selective receptions of transmitting species is made possible in a selective call unit.The wireless system is driven or cut off automatically according to the reception content through a control unit. By these means, the operator needs to perform only one addressing call and one clearing operation even when multiple intelligence medias are sent, and the operation can be simplified.
