Description
The Headset/Handset Adapter can be used to connect the Duet Executive or
Quattro2 DTI to a telephone that has no headset connection. The adapter will
take advantage of the handset connection to your phone and allow for both
your handset and Phoenix Audio device to be connected.
The buttons on the adapter allow you to switch between the Phoenix Audio
device and your handset with an aditional "mute" button
option.
