The D400 is a DECT USB adapter used to provide the best wireless connection and acoustic sound quality to your new Savi 8200 UC headset.  DECT is a different wireless technology compared to the typical WiFi and Bluetooth found on most computers.

This adapter includes a DECT radio and behaves like a soundcard, once connected to your computer or laptop, works with all your apps that use audio.

Typically, your D400 USB adapter is subscribed (connected) to your headset. In the event your adapter is disconnected, or it was purchased separately. You will need to subscribe your headset to the adapter.

• Put your DECT USB adapter into subscription mode by double pressing the subscription button until the USB adapter flashes red and green
  
  
• Subscription is successful when you hear "pairing successful" and "base connected" and the DECT USB adapter LED is solid green.
  
  
• NOTE If the USB adapter LED goes solid red after flashing red and blue, the subscription attempt has failed and should be repeated.
