Buttons and LEDs
The 10 button LED add on module 
and the 20 button keystrip add on 
module have programmable feature 
buttons that can be assigned as CO 
Line, Directory Number, DSS, One 
Touch Speed Dial or any other 
programmable feature. 
When a Programmable Feature 
Button is programmed as a DSS 
button or a Line button, it will have an 
LED that provides a status of the 
outside line or station assigned to it. 
The DSS button acts like a speed dial 
button to a specific extension.
A station or line shows steady red when in use by others; green when in use by 
your extension.
A DSS LED will flash red while making a call and turn intermittently green once 
connected.
An outside Line LED is green when the outside line is in use by your extension. It 
is red if it is in use by another telephone user.
