Extension LEDs
Most of your telephone’s fixed function keys, line keys and
program-
mable repertory 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.
