Installing Your Extension
Installing Your Extension’s Label
Your extension also comes with a label that identifies each fixed
function key’s use. You may also indicate what functions have been
programmed on the various repertory keys integrated on your
extension (see the “ Physical Programming of Your Extension ”
section.)
This label is protected by a plastic cover.
To insert or remove the label, lift the protective cover as illustrated
below.
Note: If you need a new label, contact your system
administrator.
