Where did you get that 1062 phone? Did you buy it retail from Amazon, Newegg, Fry's, etc, or is it from eBay or Craigslist, or ??
If it was purchased at retail, it would have come with an AC wall power adapter and an Ethernet cable. If DialPad supplied it to you, they may have sent it without the AC adapter, because the unit is also sold for large-enterprise installation to be powered over the Ethernet cable (PoE). If you did get it from DialPad, I have to believe they would provide setup help.
