Paper labels
Next to each call/line appearance button and feature button is a paper label. The label identifies
the call/line appearance number or the feature that has been programmed on the button by
your system administrator. You can remove the labels if you want to change a label or write
on a blank one. Printed labels are also available for your telephone. See your system
administrator for more information.
