ABSTRACT:
In a radio pager, a power-backup memory is provided for storing messages. On receiving a paging signal, a message contained in it is stored into the memory and the user is alerted with a first sound pattern. A specified label is attached to the stored message if it is not answered by the user within a prescribed interval. When the pager is turned off for battery savings purposes, the message is kept in the memory and when it is turned on again, the memory is searched. If a message attached with the specified label is detected, the user is alerted with a second sound pattern which is different from the first sound pattern. The different sound allows the user to quickly recognize that he is alerted by an uncompleted page.
