Included with the Duet are:

your VOIP needs. This cable is all you need in order to operate and use the Duet
with your VOIP applications.

2. Two RJ11 (4 position 4 contacts) to RJ11 cable (same connectors as your
telephone handset). These cables will connect your Duet to a telephone that is
equipped with a standard RJ11 type headset connector (typically IP
telephones)*. Some telephones will work with one of the cables and some with
the other one.

3. An RJ11 (4 position 4 contacts) to 2.5mm cable. This cable will connect your
Duet to a telephone (or cellular phone) that is equipped with a standard 2.5mm
headset connector*.

4. A 110-220VAC to 5VDC converter. This converter will provide power to the Duet
if a USB connection is not available.

* Please consult with your IP Telephone provider or your telephone / cellular phone user

manual for compatibility. Only devices that can use standard headsets (with either RJ11
connector or 2.5mm connectors) can be used with the Duet. Phoenix Audio
Technologies is not responsible for any damage that will be caused to your equipment if
