Panasonic A Series (616)

[pcomms]

I have an old Panasonic A Series 616 telephone system and I need to connect an external music on hold source. Can someone tell me what programming step I need to change the default setting in the system from "Tone on hold" to External Source.
Many thanks

if you are in the states the kx-t 61610-3 by default is set
for bgm by default and all you need to do is plug in the source!!!
