GENERAL INFORMATION
Your digital telephone has been designed to provide easy access to the
wide range of features offered by your telephone system. Each digital
telephone is equipped with a dialpad, 26 feature buttons, volume control
up-and-down buttons, and a handset. (A second modular connector can
be used for a headset or other external device.) The feature buttons on
each side of the dialpad are fixed, and their functions cannot be
changed. The feature buttons above the dialpad are flexible and can be
changed in programming.
Many digital telephones in your system are provided with specific buttons
that activate features. This is for your communications convenience, by
speeding and enhancing telephone usage. However, because the
system is so feature-rich, not all of its features can be assigned buttons.
These additional features are accessed by dialing codes (which are
indicated in this guide by appearing after the button, usually in
parentheses). This user guide provides step-by-step instructions for each
of these features.
NOTE: It is possible that your digital telephone may not be able to
access all of the listed features. This is because feature accessibility is
assigned by a Station's Class of Service in system programming.
