How do I enable the DD10K DECT Dongle on my Yealink phone?

First, ensure that the phone’s firmware is current or up to date.
Insert the DD10K Dongle in to the USB port of the phone and reboot the phone.
Set the DECT base station to registration mode.
Once phone has booted up and is idle, press the Reg softkey to register phone to the base station and enter pairing password (default: 0000)
