ABSTRACT:
An electronic device detects whether a warning status has occurred and if the warning status is not released within a predetermined time, warning information is transmitted to a registered device. If the warning status is not released in spite of transmitting the warning information and if the user is not near the device, warning information is transmitted to one or more hand-held terminals in an external network according to predetermined order. If the warning status is released within a predetermined time having elapsed from the transmission of the warning information to the hand-held terminal, warning released information indicating that the warning status has been released is transmitted to the hand-held terminal.
