Abstract
A radio pager receives a signal having a selective calling signal portion and message signal portion and examines the selective calling portion of the signal for its own ID code. Upon detecting a match, an alert signal is provided and the message signal portion is stored in a memory if it does not match any of the message signals already stored. A counter also keeps track of the number of stored messages. The messages can be sequentially displayed when desired.
