information on BLF key LED indicators, refer to LED Instructions on page 4.
You can press a BLF key to dial out the monitored phone number when the monitored
line is idle. You can receive a visual or/and an audio alert (if enabled), and also pick up
calls that are received on the monitored line. For more information, contact your system
administrator.
