STAR BIPHASIC WAVEFORM

The waveform generated by the Responder AED is a BIPHASIC TRUNCATED EXPONENTIAL waveform that is
compliant with ANSI/AAMI DF2 and DF39. The following is a graph of the waveform voltage as a function of
time when the AED is connected to a 50 Ohm resistive load. (See figure A1 and Tables A1through A3)
