PROBLEM TO BE SOLVED: To detect battery voltage, urge a user to replace a battery at an initial stage of reduction of battery voltage, and stop function of a wireless remote-control device for an air conditioner at the next stage. SOLUTION: A battery voltage detection circuit 40 detects voltage of the battery 30, and a reference voltage value A reduction determining means 14 outputs an alarm display signal to a voltage reduction display means 60 when the detected voltage of the battery is below a reference voltage value A. The voltage reduction display means 60 displays battery replacement alarm display based on the alarm display signal. A reference voltage value B reduction determining means 15 outputs an all function stop signal to an all function stop means 70 when the detected voltage of the battery is below a reference voltage value B smaller than the reference voltage value A. The all function stop means 70 stops all functions of the wireless remote-control device for the air conditioning machine based on the all function stop signal. COPYRIGHT: (C)2004,JPO
