5-66 MERLIN Plus System Features
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, 1-800-222-PART, and ask for order number
105400030 (for black BIS-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.

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 semen.
