6446-423 ABSTRACT OF THE DISCLOSURE A paging receiver includes a receiving section for receiving a paging signal which includes a preamble signal, a synchronization codeword and an address codeword. A switch controls power supply to the receiving section in response to a control signal. The preamble signal is detected to produce a preamble detect signal, the synchronization codeword is detected to produce a synchronization codeword detect pulse and, the address codeword is detected to produce an address codeword detect pulse. An error detector detects an error in the address codeword and produces an error detect pulse when the number of errors detected is greater than a predetermined value. A controller, in a waiting mode, generates the control signal intermittently at a predetermined interval, generates the control signal continuously for a predetermined duration when the preamble detect pulse is received during the intermittent gen- eration of the control signal, generates the control signal at a predetermined timing when the synchronization codeword detect pulse is received during the continuous generation of the control signal and generates the control signal at the predetermined interval when the error detect pulse is received during the generation of the control signal at the predetermined timing. The generated control signal is applied to the switch. Improved battery saving efficiency is achieved. P-3720
