CHANGING YOUR SYSTEM LATER

Basic changes to the way your system operates—that is, changes to the switch set-

tings on the control unit—may erase important system administration that is now in place. To change switch settings, turn to "Setting Your Control Unit," page 22, and follow the instructions for the switch you want to reset. Sinceyou won’t be perform-

ing the entire procedure, be especially careful not to skip any steps that are required. Follow the general instructions below to prevent this from happening.

General instructions for resetting control unit switches:

1.Set the On/Off switch on the Power Module to Off.

2.Set switch A to Administer (down).

3.Follow the instructions for the switch you intend to reset.

4.Turn the On/Off switch on the Power Module to On.

5.Perform any required readministration or reprogramming discussed below in “Notes on Resetting Control Unit Switches.”

6.Set switch A back to Attendant (up).

Notes on Resetting Control Unit Switches

Whenever you change the setting of a switch on the control unit, you will probably have to make other changes in your system. Keep the following in mind:

●If you add or remove attendant consoles (switches B through E), you have to reassign special lines and features to the voice terminals whose function you have just changed.

●If you change the setting of the Pooled/Square switch (switch F), you erase all system line administration and voice terminal programming that was formerly in p/ace. You have to completely readminister all your lines; set up pools and Dial Access to Line Pools, if these apply; and reprogram all your voice terminals.

●If you change the setting of the Dial Access/Button Access switch (switch G), you must reprogram individual voice terminaIs accordingly. The system will automatically assign a different function to the two buttons above lntercom- Voice. You must assign line pools to particular buttons (Button Access) or give the voice terminal access to specified line pools (Dial Access). You must also assign individual lines to buttons.

●If you change the setting of the 1-8 lines/>8 lines switch (switch H), you cancel any special line administration or programmed features on yourattendant con- soles. The setting of this switch determines how the system automatically assigns lines and intercom numbers to the buttons on attendant consoles. it

also determines the function of certain buttons on the attendant/administrator console when the console is in administration mode. (See “Initial Feature Assignments for Attendant Consoles,” pages 85 and 86.) Note that the switch setting you select does not always have to correspond to the number of outside lines you actually have. For example, if you have eight or fewer lines but plan to grow beyond eight lines within a year or two, you might be wise to set switch H to >8 Lines in order to simplify administering the system later.
