Using and Programming
Features
You can use most of your phone’s features either by pressing
programmed line buttons or by dialing feature codes,
depending on the following:
the number of unlabeled line buttons.
If all the line
buttons have lines assigned to them, you can use features
only by dialing feature codes. If there are unlabeled line
buttons, you can program features onto them. You can
then use the feature by pressing just that button instead of
dialing the feature code.
