 NOTES: 

•  After you change an extension number, you can 

check to make sure that the number was not 
already being used. Press a line button on the 
set you are setting up. If the extension number 
is already being used, the other system phone(s) 
using the same extension number beep, and 
they display 

IS ALREADY USED.

•  If you want to assign an extension number 

that is already being used, do the following: 
Identify the set that has the extension number 
you want to reassign, disconnect the telephone 
line cord connected to its 

L1/L2 jack so that 

its extension number is available, and assign its 
number to the new set. Then you can reconnect 
the set to Line 1, and assign it an unused 
extension number.
