The 2010 AHA Upgrade is now available for the Zoll AED Plus. With this upgrade, the new Real CPR Help guides the rescuer to ensure that chest compressions reach a depth of at least two inches. All AED Plus units can be upgraded to the new AED Plus version (Software v6.24) no matter when you purchased your AED.The 2010 AHA Upgrade Kit comes with the Zoll Administrative Software (which will need to be installed on your PC) and an infrared cable for data transfer. The upgrade kit also comes with two (2) faceplate stickers to cover up the icons no longer used in the rescue, which are giving breaths to the victim. The sticker placement is optional, but the Zoll AED Plus will skip these steps in the rescue process. The Zoll Administrative Software (ZAS) can be used on an unlimited amount of AEDs, but only two stickers are supplied with each kit. To order more stickers, please call 855-233-0266.After upgrading your Zoll AED Plus, please make sure to register the upgrade with Zoll .
