Portable communication apparatus

摘要

To minimize an occurrence of run-out of power in a battery in the middle of communication and an occurrence of a communication error caused thereby. The residual amount of power in the battery is detected. Communication is enabled only when the residual amount of power in the battery exceeds a predetermined amount. Information relative to the residual amount of power in the battery is displayed to allow an operator to recognize the residual amount of power in the battery. Further, information relative to the residual amount of power in the battery is transmitted to the transmission side so that information in excess of the residual amount of power in the battery on the receiving side is not transmitted to the receiving side.
