• Manufacturer Reason for Recall: Software anomaly occurs when a user adds one or more vials to the cart and subsequently returns to the Activity Calculator to modify one or more input. When a user modifies an input and selects "Recalculate", the dose calculation is updated correctly; however, any vials that were previously added to the cart are not automatically updated to reflect the revised calculation.
