If the EMG system specified in the Hardware Configuration has clipping and line interference outputs, these lights will illuminate in EMGworks® when the signal is being clipped or there is line interference in the signal. If the EMG system specified in the Hardware Configuration does not have clipping and line interference outputs, these lights can be disabled by choosing Options from the Tools menu and un-checking the Display Clipping and Line errors check box in the Options dialog box. The control signals for the software indicators come from the Bagnoli 4/8/16 Main Amplifiers.
