Hi, I recently sold an ActiVAC, and the lady I sold it to says that it keeps giving her the error "Service timed out, 0 days left, enter code" and then it shuts off after 15 minutes, making it useless. Does anyone know how to fix this and what the code is? I just happened to find it at a Goodwill, so I don't really know much about it and don't have any of the codes or the manual for it. Also, does anyone know if there's anywhere you can download a manual? She already tried contacting KCI, and they were of no help and just wanted her to give them the machine. If anyone knows anything about how to fix this, it would be extremely appreciated. Thanks!
