The country code selection is for non-US model only and is not available for all US models. Per FCC regulation, all WiFi products marketed in US must be fixed to US operation channels only. RF Exposure Information (SAR) This device meets the governments requirements for exposure to radio waves. This device is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the U.S. Government. The exposure standard for wireless devices employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC/ISED is 1.6W/kg. *Tests for SAR are conducted using standard operating positions accepted by the FCC/ISED with the device transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the device while operating can be well below the maximum value. This is because the device is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. While there may be differences between the SAR levels of various devices and at various positions, they all meet the government requirement. This device has also been tested and meets the FCC/ISED RF exposure guidelines for use with an accessory that contains no metal and positions the handset a minimum of 15mm from the body. 9
