48-Button Attendant Adjunct
Instruction Card
Introduction
The attendant adjunct provides pre-set intercom extension buttons for
one-button dialing of all the telephones in the system, indicator lights
for the status of the telephones, and buttons for sending and canceling
messages and turning Night Service on and off.
Installation
The attendant adjunct must be plugged into a station jack numbered
one higher than the telephone set with which it is paired. For example,
if the adjunct is to be used with telephone 10, it must be plugged in at “S”
jack 11 at the controller. If used with telephone 25, it must be plugged
into jack 26 at the controller. You do not have to customize or change
previous customization settings for the adjunct’s station jack.
The intercom extension buttons are numbered from 10 through 57,
starting at the lower left and ascending left to right, bottom to top. You
should label the buttons on your adjunct with the name or location of
the telephone with that intercom extension number (for example,
John
Evans
or Shipping).
Labeling Buttons
To remove old labels:
● Insert end of paper clip into notch of clear cover
● Slide cover sideways
● Lift cover and label
To add new labels:
● Fill out label
● Replace label and cover (rough side up)

You can press an intercom extension button everywhere the User Manual
(or Reference Card) instructs you to

If the telephone paired with the adjunct is not in use, you do not have to
press the INTERCOM button on your telephone when using the adjunct
to place an intercom call. For example, to call a telephone in your system,
● Press intercom extension button (speaker turns on automatically).
● Lift handset (if desired).
If, however, you are using the telephone or have calls on hold, you must
press the INTERCOM button before placing a call using the adjunct.

Light Patterns
You can tell what activity is occurring at the telephones in your system
by looking at the indicator lights next to the intercom extension buttons
on your attendant adjunct.
● If the light is OFF, the telephone is idle.
● If the light is ON, the telephone is busy.
● If the light is FLASHING rapidly, you are being signaled or called
from that telephone.
● If the light is FLASHING slowly, that telephone is receiving an
intercom call that you may answer by using the call pickup procedure
described in the User Manual.
