Why it was recalled

Firm has discovered during product monitoring that on a few systems the gradient cable connections did not meet their specifications after installation.

Root cause (FDA determination)

Nonconforming Material/Component

Action the firm took

Siemens initated their recall of the device on March 31, 2001, by sending a Customer Safety Advisory Notice/Letter to affected consignees. The letter identified the product, the problem, and the action to be taken by the customer. Customers were notified that detectors will be installed in appropriate locations on the system, which will switch off the system's power electronics in the event of a malfunction in the power supply of the gradient coils, preventing damage to the system and its environment.
