Introduction
Congratulations on the purchase of your new MDC 9000 Cordless
Business Telephone, MDC stands for Multi-line Digital Cordless.
Advanced radio technology and digital transmission provides more
power, extended range, greater clarity, and higher security. This
phone was designed to AT&T's high standards for reliability and
convenience.
The handset is portable. This portability enables you to move
about your work area or home with freedom, without giving up the
features of a corded phone.
An optional headset can be connected to the handset to allow
hands-free conversation. For ordering information, see “Ordering
Replacement & Optional Parts.”
This booklet describes MDC 9000 installation. Also included with
the phone is a Quick Reference that contains information about
displays, controls, base connectors, compatibility and trouble-
shooting.
After you have installed your phone and understand its controls
and displays, use the programming and call handling instructions
that come with your phone system. Follow the user instructions for
