I am trying to change the music on hold from the internal to external source. Being new to this sytem, I don't know where to find it. I am programming from a multiline phone, can get to programming, but can't find the music setting. Feature 3 gives me that is is SP013, V3.00

Any help would be appreciated.

I am helping out a company who had a fire in their old building and inherited this phone system, so I have no manuals. I would be interested in obtaining a CD with manuals for a small fee.
