Abstract
A data display pager capable of automatically protecting a particular message over a limited period of time. The receiver stores a message signal in a message signal storage area included in a controller thereof. When the pager detects protection information made up of a protection time signal indicative of a protection period and a set of particular marks, it protects the message signal over the protection time. The message signal is protected in either of two modes which are discriminated from each other on the basis of the number of or type of marks. During the protection time, the stored message is displayed in a first mode wherein a message without the protection information appears or in a second mode wherein the entire message appears, depending on the above-mentioned protection mode. On the expiration of the protection time, the stored message signal has, in a first protection mode, the protection information thereof deleted or has, in a second protection mode, only the particular marks thereof deleted.
