Introduction to Your Extension

Extension LEDs

Most of your telephone’s fixed function keys, and line keys feature 

an LED.
This is also true of the repertory keys on any additional satellite 

panels that may be associated with your extension.
Each LED indicates the status of a current call or the status of the 

service associated with the corresponding function key.
