Defibtech has released new software to upgrade recalled devices, and has lifted their ship hold on the Lifeline and ReviveR brand automated external defibrillators (AEDs).

The new software has addressed the issue associated with the voluntary
recall. The new software also includes a free upgrade of the unit to
the latest 2005 AHA Guidelines. Customers who currently have Defibtech
AEDs deployed in the field do not need to send their AEDs to Defibtech
to correct the issue, rather, the units can be easily upgraded in the
field, there where the units are deployed. The upgrade procedure is
very simple and takes only a few minutes to complete.

The recall was announced on March 7, so they were on ship hold for about a month - not a fun time for Defibtech, I'm sure.
