When a primary battery voltage detector of a the wireless selective call receiver detects the voltage drop of a primary batter, it transmits a voltage drop signal to a CPU. The CPU receives the voltage drop signal to transmit an alarm data to a control section of an information processing apparatus through an I/F circuit. The control section control a display section to display an alarm message and an speaker drive circuit such that an alarm sound is outputted from a speaker. Further, the CPU controls a power supply control circuit to connect a power supply of the information processing apparatus to the wireless selective call receiver without any instantaneous power down so that the selective call receiver can continuously receive an information and/or a program. |
