Telephone Operation
LINE STATUS
Each line’s button has a status indicator.
Note: The indicator’s flashing duration when
the line is in use is longer than the flashing
duration for an incoming call.
LINE LOCK
Each time you pick up the handset or press
SPKR PHONE to make or answer a call, the
phone's line lock feature automatically locks
to prevent all other internal stations from us-
ing that line.
You can release the line lock and let another
station join in the call by pressing the line
button. The phone rings once and other sta-
tions can join the call.
To reapply line lock during the same call,
press the line button again. A double ring
sounds and all other internal stations are dis-
connected (if they joined your call) and
locked out.
