Abstract
Abstract A paging receiver includes a receiver main body and a card-like ROM (27). The receiver main body includes a receiving circuit (23) for receiving a paging signal, reception controllers for ON/OFFcontrolling the receiving circuit on the basis of reception control data, address comparators for checking whether a calling signal received in accordance with a reception control signal is assigned to the receiver, a CPU (21) for fetching a message following the calling signal determined to be assigned to the receiver by the address comparators, a message memory (28) for storing a received message, and a display (14) for displaying the message stored in the message memory. The card-like ROM (27) is detachably mounted in the receiver main body, stores at least a part of the reception control data, and supplies the reception control data stored therein to at least one of the reception controller and the address comparator while it is mounted in the receiver main body. The reception control data includes at least one of a frame number representing a frame to be received, an address for receiving a message, and remaining reception number data representing the number of times capable of receiving contract information.
