Initial System Setup 
After the control unit is installed, you set up the system using a c ombination of 
system 
and 
telephone programming procedures. In this guide, System 
Programming procedures are identified by a code (# and three digits); Telephone 
Programming procedures are identified by the feature name only. 
Use the 
System Planner 
as a guide when programming. The following sections 
provide an overview
of the procedures you use for initial system setup. Chapter 5 
explains how to use the specific procedures. Other programming procedures are 
optional, but are strongly recommended to make the most of your invest ment. 
(See ‘‘System Programming Options’’ and ‘‘Telephone Programming Options’’ for 
details.) 
Setting the System Clock 
After supplying power to the control unit, use the following procedures: 
■System Date (#101) to set the month and day. 
■System Day (#102) to set the day of the week. 
■System Time (#103) to set the hour and minutes. 
Assigning Lines 
Key Extensions
Use the procedures described in this section to assign individual lines to  pooled 
extensions or assign lines to key extensions. (In Key mode, all extensions are  Key 
extensions; in Hybrid mode, extension 10 and any extensions set to Ke y using 
Line Access Mode (#313) are key extensions.) 
For initial setup 
only
, use Number of Lines (#104) to specify the number of lines 
that will be assigned to all system extensions. Then use the following procedu res 
as needed: 
■Dial Mode (#201) to identify any rotary lines (the default for all lines is 
“touch-tone”). 
■Line Assignment (#301) to assign lines to specific extensions (if the line 
was not assigned using the Number of Lines procedure), to remove lines 
from some extensions, or to change the button used to pick up a line at a 
specific extension. 
■Line Access Restriction (#302) to prevent an extension from receiving 
and/or
making outside calls on specific lines.
