I need help figuring out how to use this phone.
Sure. First you pick up the receiver and hit one of the first 3 buttons. Do you hear a tone?
Yes, I hear the tone.
OK. Now you dial 9 on the keypad. Do you hear the tone change?
Yes, it changed.
Well, when you hear it change, that means you have an outside line. Where are you trying to call?
I am trying to call home.
OK. Well, to dial to the outside you just now dial the number. For a call inside the company just hit the extension number. Do you know the extensions?
Yes, I have a list of extensions.
Well, if you ever need help with an extension, you can dial O.
