Abstract
Described is an electronic device for performing certain operations and includes a continuous operating unit providing operations benefitting from a backup battery for providing backup power to the continuous operating unit. The battery is installed in the electronic device at the time of manufacture and is connected to the continuous operating unit through a switch which is in the open position at the time of manufacture of the electronic device. An input device allows a user to input signals to the electronic device. A central processing unit is connected to the continuous operating unit and receives the input signals from the input device. The central processing unit contains firmware for performing the operations of the electronic device and the central processing unit closes the switch when a predetermined parameter is received from the input device. A main power source is connected to the central processing unit and the continuous operating unit for providing operating power to the central processing unit and the continuous operating unit. Also described is a method of operating an electronic device including executing an initialization procedure when an on/off control of a electronic device is actuated to an on condition, obtaining input information via an input device, analyzing the input information in a central processing unit to determine if a predetermined parameter is being input for the first time and closing a circuit between a backup battery and a continuous operating unit via a signal from the central processing unit when the predetermined parameter is input for the first time.
