ABSTRACT:
In a radio display pager, a memory has message fields and corresponding attribute fields. When a message is received, it is stored in one of the message fields which are vacant. A message stored in one of the message fields is then displayed in response to the operation of a manual operated key. A protect indication is stored into the attribute field of the displayed message if the key is not subsequendy operated within a predetermined time interval. If the key is operated within that interval, a protect indication, if present in the attribute field of the displayed message, is deleted. If a new message is received when the message fields are already full, an unprotected old message is discarded to vacate a message field in which the new message is stored.
