Does anyone know if the programming is in the system or user manual for the Mod 16 Key... It is the 616 little blue plastic jobber.

I have a client that wants different lines to ring at different locations and not at other locations. He does not want to pay for the manual he "does not need". This should say everything about the client. I know where to buy but not which one.
