Hi All,
Am new to the forum.

I'm and end-user for an Avaya Partner II phone system, not sure if thats the phone system itself or the messaging portion of the system, nevertheless that is what i've learned we have.

I'm looking for advice on how to handle the following system message;


I'm assuming that means to replace some system battery, like a CMOS battery of a computer? Nevertheless I don't want the programming to all the sudden get wiped out because of a power failure.

I don't have contract support for this phone system so I'm wondering if its a system battery that I can replace myself or if I have to bite the bullet and get a technician to replace it?

Thanks for any and all advice
