=Description=
−This decodes one or more encoded friend codes into local friend codes for use with some friend-related commands. Encoded friend codes seem to generally be retrieved from [[NWM_Services#NWM_local-WLAN_service_.22nwm::UDS.22|NWMUDS]] command [[NWMUDS:GetNodeInformation|GetNodeInformation]].
+This unscrambles one or more scrambled friend codes. Scrambled friend codes seem to be generally be retrieved from [[NWM_Services#NWM_local-WLAN_service_.22nwm::UDS.22|NWMUDS]] command [[NWMUDS:GetNodeInformation|GetNodeInformation]].
