摘要：
The present invention relates to a device for generating a signal and method for controlling operation of the same. The present invention provides a device for generating a signal, which includes an electrode (110), if connected to an external power source (200), supplied with a voltage from the external power source (200), a signal generating unit (130) having a plurality of terminals, the signal generating unit (130) deciding whether to operate the device according to a size of a voltage applied to a first terminal among a plurality of the terminals, the signal generating unit (130) outputting a prescribed signal according to the decision, and a control circuit (120), if the electrode (110) is connected to a plurality of the terminals, controlling a voltage applied to a plurality of the terminals. Accordingly, the present invention is able to control whether to operate a signal generating device (100) using an external power source (200).
