Universal Interface UI 710
The UI 710 allows you to connect a standard telephone, the
handset of the telephone and a headset of the Sennheiser
Office or Call Center series.
With the UI 710, you can then switch between the headset
and the handset.
Connecting the handset to the UI 710
Pull the Western plug of the handset cable out of the
telephone and connect it to the HANDSET socket on the
UI 710 until it locks into place. An audible “click” should
be heard.
