Such changes will, however, be incorporated into new editions of this User Guide. All illustrations are for illustration purposes only and may not accurately depict the actual device. n n 1 3 2 During SAR testing, this device was set to transmit at its highest certied power level in all tested frequency bands, and placed in positions that simulate RF exposure in usage against the head with no separation, and near the body with the separation of 5 mm. SAR compliance for body operation is based on a separation distance of 5 mm between the unit and the human body.Carry this device at least 5 mm away from your body to ensure RF exposure level compliant or lower to the reported level. To support body operation, choose the belt clips or holsters,which do notcontain metallic components, to maintain a separation of 5 mmbetween this deviceand yourbody. RFexposure compliance with any body accessory, which contains metal, was not tested and certied, and use such body-worn accessory should be avoided. EU Certication Information (Highest SAR) SAR 10g limit: 2.0W/Kg, SAR Value: Head: 0.231W/Kg, Body: 1.480 W/Kg (5 mm distance) Legal Information This device may be operated in all member states of the EU. Observe national and local regulations where the device is used. This device may be restricted for use, depending on local network.

FCC Regulations E-label This mobile phone complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This mobile phone has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment o and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. 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. The exposure standard for wireless devices employs a unit of measurement known as the Specic Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/Kg. For body-worn operation, this device has been tested and meets the FCC RF exposure guidelines for use with an accessory that contains no metal and positions the device a minimum of 1.0 cm from the body. RF exposure compliance with any body-worn accessory that contains metal was not tested and certied, and use of such body-worn accessory should be avoided. Accessory available in market and must be used to keep use distance 1.0 cm from EUT to Body for Body-worn operation. FCC Note Changes or modications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Manufacturer: Xiaomi Communications Co., Ltd.
