AED PLUS CUSTOMERS MUST PERFORM SOFTWARE UPDATE AND NOTIFY ZOLL 

December 21, 2009CHELMSFORD, MASS.–Earlier this year, ZOLL Medical Corporation (Nasdaq GS: ZOLL) began to execute a field corrective action on its AED Plus® automated external defibrillator.   While the Company has made multiple notifications, due to the broad range of customers involved the corrective action continues.  In order to ensure defective devices have been remedied, the Company has increased its efforts to notify customers via mail and telephone. Customers who have not yet performed the required software update AND submitted confirmation to ZOLL are urged to do so as soon as possible.

The Company had determined that some batteries do not work properly when used with ZOLL AED Plus defibrillators manufactured prior to February 12, 2009 (serial numbers below X_ _ _200000).  The previous version of ZOLL AED Plus Self-Test Software did not adequately detect defective batteries, which could lead to a failure to deliver defibrillation shocks during treatment of sudden cardiac arrest.

ACTIONS TO TAKE:

  1. All AED Plus devices with serial numbers below “X_ _ _200000” must be upgraded with the latest software release.  The software update can be easily downloaded from the Company’s web site and installed by the user.  
  2. Users must send ZOLL an acknowledgement that the corrective action has been implemented after updating the device software.  This confirmation is required for customers to avoid liability and for ZOLL to ensure defective devices have been remedied.

More information on this corrective action, including instructions for downloading software, sending ZOLL the acknowledgement, and ordering replacement batteries is available at http://www.zollaedplusbatteryhelp.com/  Customers can also call ZOLL Technical Support at 1 (800) 348-9011 or email Tservice_AED@zoll.com

This action does not apply to AED Plus devices manufactured after February 12, 2009 (serial numbers above X_ _ _200000).
