【発明の名称】移動無線端末及び移動無線端末におけるアラーム出力方法
Document Type and Number:
Japanese Patent JP2938017
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide a mobile radio terminal capable of appropriately displaying the residual capacity of a battery corresponding to many communication forms and outputting an alarm and an alarm output method in the mobile radio terminal. SOLUTION: In a duplex operation standby state, when a battery voltage value VR is lower than a threshold level, the alarm is immediately outputted (step 35) and the battery residual capacity is displayed at a display part (step 36). When the VR is larger than the threshold level, the potential difference VD1 of battery voltages at the time of standby and during communication is subtracted from the VR and a value VS for which the portion of voltage drop is corrected is calculated (step 38). The VS and the threshold level are compared (step 39), and in the case that the VS is lower than the threshold level, the alarm is outputted (step 41) and the battery residual capacity is displayed at the display part (step 42). In the meantime, during transmission and during the communication, the correction value VS is not calculated.
