This ingenious device
prevents other users in your
home or office from
interrupting or eavesdropping
your phone calls or causing
your modem to drop the line
whilst surfing the internet. It
looks and behaves just like a
standard double adaptor with
a clever difference. When the
extension plugged into one
socket is answered, the other extension is
automatically disconnected. LED indicators light
showing when an extension is in use. Completely selfcontained,
requiring no batteries.
