No. 5 6 Item Micro SIM slot (optional) MicroSD card slot Description Accepts a micro SIM card. It meets the requirements of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The maximum SAR value is calculated at the highest output level in all frequency bands of the mobile device. The highest SAR value reported under this standard during product certification for use of the device at a distance of zero gaps from the body is 1. 87 W/kg. For body worn operation, this device has been tested and meets the ICNIRP exposure guidelines and was included in the European Standard EN 62311 and EN 62209-2 for use with accessories that contain no metal and that position the handset a minimum of 1. 5 cm from the body. Use of other accessories may not ensure compliance with ICNIRP exposure guidelines. If you do not use a body worn accessory and are not holding the device at the ear, position the handset a minimum of 1. 5 cm from your body when the device is switched on. During use, the actual SAR level is usually much lower than the maximum value, because the mobile device works in different output levels. [. . . ] 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 poser required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. [. . . ]
