If during a phone conversation the green
light goes out, someone has activated a tap or picked up an extension.
Press the red button to resume talking, now with caution. When
Tele-Data Guard is installed on all your extensions, the extension you
pick up automatically disconnects the others! No more running to turn
off the answering machine. LED also tells you – before you pick up – if
the line is in use. Like a mini-phone system, protecting your faxes or
modems from interruption, saving you steps, and insuring your privacy.
Measures just 3-1/2"x2"x1" and requires no batteries. |
