Using Features
Press a button programmed with a feature. Some
features can be programmed onto a line button for one-
touch use or to turn features on and off. Your console may
already have features such as Night Service programmed
onto a button. You can program any unlabeled line buttons
with additional features. When a feature is programmed on
a button, just press that button to use the feature.
To program features onto line buttons, you can select the
feature from your display or you can dial a
programming code on your dialpad. Use the following
instructions to program features from the display or with
programming codes.
Before you begin programming, remove the clear plastic
that covers the button labeling card and write in the names
of the features next to the buttons to be programmed.
Replace cover with textured side up.
Some features require that you respond to display prompts
with additional entries. For example, Auto Dial requires you
to dial a phone number. Whenever you respond to a
display prompt, you need to select Enter to confirm your
entry or selection.
If you are unable to program your console, someone may
be programming the system. See your system manager.
