Reason for recall
Arietta 850 software version 4.0.0., 4.0.1, and 4.0.2 has an error in the focus point and transducer aperture settings in the SWE function. When the affected software with SWE function is used in conjunction with the C252 probe, this error can result in out of specification MI/TI acoustic output. The MI/TI acoustic output is higher than regulatory limits.
Potency and specification recalls happen when a batch tests outside its approved limits for strength, purity or dissolution, which can mean the dose delivered is higher or lower than labelled.
