Your telephone can detect another tele- phone, facsimile, or modem that is in- use on one or more of the CO lines.This 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.
