Defibtech Initially notified customers by telephone on 8/27/10. Customers were notified of the product, the problem and the action to be taken. Customers were instructed to locate affected data cards and send them back to Defibtech for evaluation. If the data card was inserted into the AED, then the customer was instructed to check the AED software version. If the software version was at 2.005, the customer was instructed to keep the AED out of service until Defibtech could evaluate the returned data card. (Any other software version indicated that the device was not affected by a faulty data card). If the software version was any other version other than 2.005, then the customer was instructed to keep the AED in service unless the original service inquiry required it to remain out of service. If the data card was not inserted into the AED, then the customer was instructed to return the data card for evaluation. For any questions customers were to contact Customer Service at (866) 333-4241 from 8:30-5pm EST, M-F.
