The agency’s classification

FDA (Devices): Class II

Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.

This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work

What this means for you

Our assessment, not the agency’s: severity 2/5 (Moderate).

Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.

Our severity reasoning: The recall is classified as FDA Class II, which typically corresponds to a moderate severity score. The source text describes a software defect causing system crashes and data unloading issues, but does not report any injuries, illnesses, or deaths, nor does it describe a direct physical hazard like radiation exposure or structural failure.
