Abstract
An electronic device may include a plurality of function sections which can function independently. A CPU can control the functions of the respective function sections by controlling a power from the battery pack. A user may select a desired reserved function section and input an available time of the desired reserved function section by operating a key matrix, thereby executing the setting such that one or a plurality of function sections thus reserved can be used during a predetermined time period. The CPU may disable functions other than the functions of one or a plurality of function sections when a battery remaining capacity Qc becomes equal to a total necessary current accumulated remaining quantity of one or a plurality of function sections reserved by setting, and may disable the function of the function section with a priority N+1 each time the battery remaining capacity Qc becomes equal to the total necessary current accumulated remaining quantity of the function sections with priorities up to a priority (e.g. order in which function sections are selected) N (N is an integer greater than 1).
