Poly Vxx 150 and 250 no phone manual just a quick reference guide (Set Up)

Poly Vxx 150 and 250 no phone manual just a quick reference guide. Trying to hook it up t my pc since I dont have a wall jack on this floor. Anyone know how to do this and update the phone date time etc? It might have been a good point to make that a wall jack or router be near by for this type of phone to be set up.
