ABSTRACT:
In data communication with power furnished from a built-in battery, the residual battery capacity is detected as power that can be currently supplied by the battery. In addition, power necessary for communication is forecast from the quantity of data for communication. The currently residual battery capacity and the necessary power for communication are compared. If the former is in excess of the latter, the communication operation is allowed, while otherwise it is inhibited. When the communication operation is inhibited, functions of parts irrelevant to communication operation are suppressed or reduced. When function suppression is done, the necessary power for communication is re-forecast for comparison from current consumed by other parts than those functions suppressed or reduced.
