<p>PROBLEM TO BE SOLVED: To selectively indicate countermeasures based on check results obtained by checking the power remaining of a portable electronic appliance. SOLUTION: When a power detection part 118 detects the voltage of a power source 125 (detected voltage) and the detected voltage is zero or higher, the detected voltage is compared with a warning indication voltage (reference value for alarm occurrence). When the comparison result indicates that the warning indication voltage is larger than the detected voltage, it is transmitted to an warning generating part 120, and the warning generating part 120 generates warning from the warning device 121. The indication of countermeasures to be taken is made by a countermeasures processing part 146. A user who operates a portable electronic appliance can select countermeasures.</p> |
