Ronald supplied what could be a solution to Jo's problem, but we had to delete it because he provided a hidden (and unsupported) command whose use COULD very easily get you into legal trouble. All countries have laws controlling how much transmit power is permitted and what frequencies may be used, changing to the wrong country-code can cause the device to violate your local laws and get you into legal trouble. Adam Conway asked the correct question. If you have been shipped -FCC devices but are not in the US, you can either return them to your reseller for the correct part number items, or Aerohive Technical Support can assist you in converting these from US to World units. That change should only be done under the direct supervision of Aerohive Technical Support.
