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, if connected to an external power source, supplied with a voltage from the external power source, a signal generating unit having a plurality of terminals, the signal generating unit 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 outputting a prescribed signal according to the decision, and a control circuit, if the electrode 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 using an external power source.
