Abstract
In a radio display paging system, a transmitted paging signal either contains an optional confidential code and a message if the message is confidential or exclusively a non-confidential message. When the paging signal is received by a destination pager, the message contained in it is stored in a message memory. If the received signal contains a confidential code, a prompt is displayed for urging a user to enter a password, and the message in memory is scrambled. If the entered password is valid, the message in memory is descrambled and displayed.
