"On a digital display phone, there are three buttons located under the display. When in "Programming" mode, the display shows labels for these buttons for the main functions you will need, for example " ", NEXT, or SEL (select)."
"If you think you have gotten mixed up, or when you are finished, you can get out of programming mode by picking up the handset and hanging it up again."
"Some phones have a "Program" button in the upper left, some have it on the bottom row above the number 3, -if the phone does not have one, then use the button labeled "Pause"
"If you wait too long between pressing buttons, the system may cancel programming mode and you will have to start over.
