When I scan the 954's User Guide, I do not see any direct references to a Privacy feature. There are a few indirect references. Here is 1 of them:

"Cannot Join a Conversation in Progress
The privacy feature prevents another set on the system from interrupting a
conversation. Make sure you press the line button to release privacy."


If I understand this correctly, a Privacy feature is automatic unless you press a line button in a certain way.

I believe later NoKSU units sold under the AT&T brand name (manufactured by VTech) have a dedicated Privacy button on the telephone.
