Your telephone can detect another tele-

privacy feature will prevent accidental
instruction by another VT4121 speak-
erphone user. The “Line-In-Use” circuit
will light the CO line button if the line is
not physically connected. For instance,
if you only have lines 1,2, and 3 con-
nected you can disable line 4( if you do
not disable that line, the lamp will re-
main lit steady even though you can’t
access the line). When you disable a
CO line the lamp and button will not op-
erate.
