Your 7406BIS Voice Terminal
The 7406BIS voice terminal is available in two models: one with a display and one
without a display. The display adds some functionality, but both models are designed
so that you can conveniently use the features of the AT&T DEFINITY®
Communications System Generic 2 and System 85.
The 7406BIS voice terminal also offers a high-quality, built-in speakerphone. You can
use the speakerphone for placing and answering calls or for using voice features
without lifting your handset, and for allowing others to participate in your telephone
conversations.
Note: For best sound quality, place your voice terminal flat on your desk or other
working area.
The display-equipped 7406BIS voice terminal is shown and explained on the following
pages. Both models (with display and without display) have the same button layout.
