ABSTRACT:
Paging system comprising a call transmitter, at least one portable paging receiver and a control transmission system with a control transmitter to which a number of transmission loops are connected encompassing essentially adjacent zones. The call transmitter is capable of transmitting a call transmission signal comprising a call address code. On receipt of a cell address code which corresponds to a call address code stored in the paging receiver, the receiver can generate a signal for the user of the receiver by means of a signalling member. The control transmission system is capable of transmitting by means of the loops a control transmission signal comprising a control command. On receipt of a control command by the receiver, the receiver can go into and remain in a state corresponding to the control command, in particular on or off. A control part of the receiver preferably puts the receiver into a predetermined state, in particular if the receiver has not received a control command, in particular an "on" command, for a predetermined period to time.
