This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. Information to user. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Information to the user. Note: This equipment 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 off 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 different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. Specific Absorption Rate (SAR) information: This mobile phone meets the government's requirements for exposure to radio waves. The guidelines are based on standards that 5 were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons regardless of age or health. FCC RF Exposure Information and Statement The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device types: X6528B (FCC ID:2AIZN-X6528B) has also been tested against this SAR limit. The highest SAR value reported under this standard during product certification for use at the ear is 1.17 W/kg and when properly worn on the body is 0.78 W/kg. Body-worn Operation This device was tested for typical body-worn operations. To comply with RF exposure requirements, a minimum separation distance of 1.0 cm must be maintained between the user’s body and the handset, including the antenna. Third-party belt-clips, holsters, and similar accessories used by this device should not contain any metallic components. Body-worn accessories that do not meet these requirements may not comply with RF exposure requirements and should be avoided. Use only the supplied or an approved antenna. 6 For DTS patents, see http://patents.dts.com. Manufactured under license from DTS Licensing Limited.

General SAR test exclusion guidance c) For frequencies below 100 MHz, the following may be considered for SAR test exclusion (also illustrated in Appendix C): 1) For test separation distances > 50 mm and < 200 mm, the power threshold at the corresponding test separation distance at 100 MHz in step b) is multiplied by [1 + log(100/f (MHz))] 2) For test separation distances ≤ 50 mm, the power threshold determined by the equation in c) 1) for 50 mm and 100 MHz is multiplied by ½ 3) SAR measurement procedures are not established below 100 MHz Measurement Result: For NFC, the power of EUT: E Field@3m is 67.08dBuV/m =-28.12 dBm(0.0015mW) Note: E[dBμV/m] = EIRP[dBm] + 95.2 for d = 3 m. SAR test exclusion threshold for NFC(13.56MHz) separation distance < 50mm =[474*(1 + log(100/f (MHz)))]/2 = 443mW >0.0015mW Result: Compliant.
