- Action
- The firm issue a DEVICE CORRECTION letter to their customers on 2/11/2008. The letter informs the customers of the Emergency Rundown Switch Unit (ERDU) defect and provides a warning which lists instructions for the safe use of the ERDU Unit. The letter informs the customer(s) that their local Hitachi Field Service Engineer (FSE) will be scheduling a visit to test the ERDU in order to verify its state of operation. The letter also states that This test requires specific tools in order to verify the operation without actually quenching the magnet and that Hitachi will begin the test ING in March, 2008 and will continue the program until all installed ERDU units are verified. Should an emergency arise requiring you to activate the ERDU, verify the Emergency Run Down light illuminates and that the magnet does quench (a very loud noise will be audible) before entering the scan room without screening personnel and equipment. Notify the Hitachi Customer Service Department at (800) 800-4925 immediately should you initiate an Emergency Run Down.
