Abstract
A personal radio paging receiver includes a radio section, a control section, a DC/DC converter, and a secondary battery. The radio section receives/demodulates an external radio signal and outputs a POCSAG signal. The control section divides the POCSAG signal into a first sync signal portion and a second batch signal portion, and outputs a control signal during a period of the first portion. The DC/DC converter operates for only a period during which the control signal is received. The secondary battery supplies power to the control section in synchronism with the second portion. The DC/DC converter is supplied to charge the second battery.
