I have a Southwestern Bell telephone CICCO CT100 wall or desk mounted, with a cord. I have lost the owner's manual. I need to turn off the answering service. Can I get a copy of the owner's manual on line? This phone has 'smart keys'. There is no key labeled "answering service".

You asked for the manual I got one and gone through it.
