Product Description
DigitalDiagnost C50 1.1
Reason for Recall
Following a system restart where the Table Height 2 (TH2) is the default setting and then switched to Wallstand VS2, operators will see an incorrect orientation of the image on the first examination due to an issue in the firmware of the Wallstand VS2 board. The system will rotate the amplimat field selection by 90 degrees. The wrong amplimat field selection may cause an incorrect dose of radiation to occur. Additionally, the anatomic position markers may become mispositioned and could potentially be associated with the opposite side of the anatomy. (Added 1/3/2023), Expansion of the root cause to include incorrect amplimat field selection by 90 degrees following the first exposure using Wallstand VS2 and a subsequent system restart. Previously, this issue only occurred following a system restart where the Table Height 2 (TH2) is the default setting.

Frequently Asked Questions
A software recall means the device's embedded software or firmware has a defect that could affect its performance or safety. Many software recalls are corrected through firmware updates that can be applied without physically replacing the device. For implantable devices, the update may be delivered wirelessly during a routine clinic visit. For external devices, the manufacturer may provide updated software files or replacement units. Contact your healthcare provider to determine whether your specific device and software version are affected and what action is recommended.
Class I recalls indicate a reasonable probability of serious adverse health consequences or death from the defect. Class II recalls involve products that may cause temporary or medically reversible adverse health consequences, or where serious consequences are remote. Class III recalls cover products not likely to cause any adverse health consequences, typically involving technical regulatory violations. The classification guides urgency — Class I recalls require immediate action, while Class III may simply involve returning a product or acknowledging a labeling change. Always read the specific recall notice for recommended patient actions.
Report problems with medical devices to the FDA through MedWatch at 1-800-FDA-1088 or online at FDA.gov/safety/medwatch. Healthcare facilities are required by law to report device-related serious injuries and deaths. Patients and consumers can also report voluntarily. Include the device name, manufacturer, model number, and a description of the problem and any patient outcome. Reports from patients and clinicians help the FDA identify emerging safety signals and may trigger investigations that lead to recalls of dangerous devices.
