You don't have a Partner II you have a Partner ACS. That message has nothing to do with the messaging system, it means that the memory backup batteries for the ACS are low. Unlike the Partner II the batteries are simply a couple of AAA Duracells that are easily replaced. There is a battery cover on the bottom front of the ACS processor. WITH POWER ON replace the batteries. The message on extensions 10 and 11 will go away.
