More Information
Summary:To carry out processing to be executed upon occurrence of an emergency, a mobile phone includes a power control portion for supplying driving power, a RAM capable of storing data in the state where the driving power is not supplied from the power control portion, a crime prevention switch for detecting occurrence of an emergency, and a control portion which is driven by the driving power supplied from the power control portion. The control portion stores an emergency flag in an ON state indicating an emergency mode in the RAM in response to detection of the emergency by the crime prevention switch, and carries out emergency processing. When the control portion is activated as the supply of the driving power from the power control portion is started, it carries out the emergency processing if the emergency flag in the ON state is stored in the RAM.
