Zusammenfassung:PROBLEM TO BE SOLVED: To solve a problem that a user gets into an extremely inconvenient state if a battery of a wireless device is rapidly consumed when the user goes out and communication becomes impossible. SOLUTION: A battery voltage detection method has a battery voltage detection means 20 generating an alarm signal when a voltage of a battery 10 decreases to a predetermined voltage. Since the number of wireless handsets can be determined to be two when a predetermined radio authentication communication occurs during 1.5 T, an alarm start voltage set in the battery voltage detection means 20 is changed, for example, from 2.5 V to 2.7 V.
