To set up an IP phone, you typically need that phone's IP address, which you can get from your router or from the phone. On this phone, press the OK button (the round center button) and the phone will show the Status screen; look for IPv4 — that is your phone’s IP address. Alternatively, if the OK button is disabled or customized, press Menu, go to Status, select Network, and look for IPv4 Address.

The first time you log into the phone, you will be prompted to update the password. The default username/password are both admin (if not, look for a sticker on the bottom side of the phone).
