The controller transmits a testing signal to the device in response to a start voltage and obtains a state signal and a site signal. The first display is electrically connected to the controller for displaying a first image in response to the state signal. The second display is electrically connected to the controller for displaying a second image in response to the site signal. By observing the first image and the second image, we can gain the states of the device.
