Physio-Control LIFEPAK 500 Software Upgrade

[RWC130 594]

I'm looking for the upgrade kit for the Physio-Control

LIFEPAK 500 AED (Biphasic)

It was recently given to me. I got a new battery and AED pads but noticed when powering up it says 2003.

It needs the upgrade. Can anyone help?

I know they do have kits online. Looking for something a lot cheaper.

Thanks.... K
