Abstract
A receiving frame controlling unit 4a for controlling receiving operations of a plurality of frames individually, and a receiving state detecting unit 1b for detecting whether or not a receiving state is in or out of a service area of the base station are provided in a CPU 4, wherein the power saving or conservation can be achieved in the out of the service area status by halting frame receiving operations when the receiving state is out of the service area. Also, according to an error rate of received radio information, or according to a time zone which is set arbitrarily to particular information broadcasting addresses by a user, the power saving or conservation may be achieved by reducing the number of receiving frames. Further, if the receiving state is out of the service area and also the electric field strength is low, the power saving or conservation may be achieved by executing a short-time standby operation to monitor only the electric field state.
