Only the Platinum makes a big deal about even giving you a sound effect if the Auto-Abort is engaged. Most machines would only have an audible sound effect if it aborted after the actual treatment energy had started firing.
Yes ist does. But nevertheless my impression is that the auto-abort sensor of the (old) Junior reacts faster, and its autor-sensor feature seems to be slightly less sensitive thus reducing the danger of misfirings. IMO the auto sensor of the old machine is a bit easier to handle (and i do not miss the “missing” beep upon abort) than that of the platinum. Anyway both are very useful as long as insertions are not too difficult.
