DESCRIPTION
Some 34-Button speakerphone voice terminals, namely, the BIS-34D and the
34-Button (SP-34D) voice terminal with display, are equipped with a display
unit. You can also purchase one separately and add it later to a 34-Button
(SP-34) voice terminal. To order the Display Unit, call the AT&T National
Sales Parts Center’s tollfree number, l-800-222~PART, and ask for order
number 105400030 (for black BE-34 voice terminals).
The display provides information that helps you handle calls and program
your voice terminal more easily. For example, when you dial a number or
touch an Auto Intercom button, or when you receive an intercom call or a
returned transfer call, the number associated with the call appears on the
display screen. When you are programming a button, the display unit can
help you check if the button has a feature already programmed onto it. If you
have not yet programmed a feature on the button, the word “blank” appears
on the display screen.

CONSIDERATIONS
You can also use the display unit for providing an alarm, timing calls that you
place or receive, and displaying the time, day, and the date. See Figure 5-2.
To adjust the clarity of the display screen characters, turn the contrast
thumbwheel until the numbers and letters are clear.
Only the numbers for incoming intercom calls are displayed on the screen;
the display unit does not show the identification of incoming calls from
outside the system.
When the display is idle, the screen shows the time, day, and date.
The information appears on the screen for a maximum of 10 seconds. If you
disconnect a call or touch another display option button, such as the
Time/Timer button, before the 10 seconds are over, the display is replaced
with the time/date display.
Dial the numbers and characters of your calls slowly so that the display unit
can place them correctly on the screen.
