摘要:
According to the present invention, an analog-mode discharge characteristic storage area (21a) and a digital-mode discharge characteristic storage area (21b) store threshold data of remaining battery display in an incoming-call standby status in an analog mode and that in a digital mode, respectively. A remaining battery determination means (20a) determines a remaining battery level corresponding to a selected communication mode based on both a voltage of detected by a voltage detection circuit (32) and data stored in the analog-mode discharge characteristic storage area (21a) or the digital-mode discharge characteristic storage area (21b). A remaining battery display control means (20b) causes the remaining battery to be displayed on an LCD display of a control unit (22) in accordance with a determination result of the remaining battery determination means (20a).
