18) Call appearance/
feature buttons
At least 3 of these 10 buttons are devoted to incoming
and outgoing calls (call appearances) and are labeled with
an extension number; the remainder access features
(feature buttons) and are labeled with a feature name.
Each has a red in-use light to tell you that this is the line
you are using or that this is the line you will get when
you lift your handset. The green status light next to
each call appearance and feature button tells you the line
or feature is being used.
