RECEIVER HAVING AN INDIVIDUAL SELECTIVE CALL FUNCTION AND A SECURITY FUNCTION FOR PREVENTING UNAUTHORIZED USE OF THE RECEIVER

摘要

A receiver with an individual selective call function includes a ROM for storing an individual selection number in which a secret number of the receiver is registered. A data control unit compares a secret number registered in its own memory and the secret number registered in the individual selection number ROM of the receiver, and when they are not equal, the read/write operation of the individual selection number ROM is disabled.
