DX-80 Installation & Maintenance
The display also provides a visual reference to call progress and call duration, as well as time and date
information. The display enables the user to send and receive visual advisory and callback messages.
Users may select from six pre-programmed messages (i.e., "IN A MEETING," "OUT OF OFFICE"),
or they may create a custom message. Callers from other DETs to an extension with a message active
will receive the visual advisory message on their LCD display.
Each digital speakerphone has 30 programmable Feature Buttons to aid the user by providing direct
access to system features and resources. There are also three interactive buttons and 8 fixed function
buttons. Note: The volume button bar represents two operations: volume up and volume down.
Each DET is equipped standard with a 2.5 millimeter headset jack. Users can toggle their speaker-
phone operation in and out of a special "headset mode". This mode allows the user to easily activate
the headset jack via the ON/OFF button as an alternative to using the speakerphone. Thus, headset
mode is easily enabled or disabled so that users can quickly select between use of the headset or speak-
erphone operations. Note: The DET must be idle to change this setting.
Each speakerphone is also equipped with a status lamp to aid in user operations. The lamp is dual
color (red / green) and indicates various modes of operation, such as messages/voice messages
waiting, incoming calls - distinctive for CO and intercom, in-use indication for speakerphone mode,
headset mode, etc.
