Please remind the front and back of the plug. 2. Use only INFINIX charger and cables. Other chargers or cables may damage the device. This will invalidate yo ur phone warranty. 5 Emergency call If any emergency arises, dial 112/911 (or other emergency call number) for emergency help. Due to the nature of cellular networking, the success of emergency call is not guaranteed. FCC Warning: 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, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This equipment has been tested and f ound 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 us ed 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, th e 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 co nnected. ‐Consult the dealer or an experienced radio/TV technician for help. 6 The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device types X657B (FCC ID: 2AIZN‐X657B) has also been tested against this SAR limit. The highest reported SAR values for head, body‐worn accessory, and product specific (Hotspot) are 1.00 W/kg, 0.75 W/kg, and 0.81 W/kg res pectively. The Max simultaneous SAR is 1.21 W/kg. This device was tested for typical body‐worn operations with the back of the handset kept 10mm from the body. To maintain compliance with FCC RF exposure requirements, use accessories that maintain a 10mm separation distance between the user's body and the ba ck of the handset. The use of belt clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided. 5G For 5150‐5250 and 5725‐5850 fr equency band, Operations in the 5150‐5250 and 5725‐5850 band are restricted to indoor usage only. 5G: Any emission is maintained within the band of operation under all conditions of normal operation. The max. frequency stability is less than 20ppm.

Figure 1 – MVG COMOSAR Dosimetric E field Dipole Probe Length 330 mm Length of Individual Dipoles 2 mm Maximum external diameter 8 mm Probe Tip External Diameter 2.5 mm Distance between dipoles / probe extremity 1 mm 3 MEASUREMENT METHOD The IEEE 1528, OET 65 Bulletin C, CENELEC EN50361 and CEI/IEC 62209 standards provide recommended practices for the probe calibrations, including the performance characteristics of interest and methods by which to assess their affect. All calibrations / measurements performed meet the fore mentioned standards. 3.1 LINEARITY The evaluation of the linearity was done in free space using the waveguide, performing a power sweep to cover the SAR range 0.01W/kg to 100W/kg.

The information contained herein is to be used only for the purpose for which it is submitted and is not to be released in whole or part without written approval of MVG. 3.2 SENSITIVITY The sensitivity factors of the three dipoles were determined using a two step calibration method (air and tissue simulating liquid) using waveguides as outlined in the standards. 3.3 LOWER DETECTION LIMIT The lower detection limit was assessed using the same measurement set up as used for the linearity measurement. The required lower detection limit is 10 mW/kg. 3.4 ISOTROPY The axial isotropy was evaluated by exposing the probe to a reference wave from a standard dipole with the dipole mounted under the flat phantom in the test configuration suggested for system validations and checks. The probe was rotated along its main axis from 0 - 360 degrees in 15 degree steps. The hemispherical isotropy is determined by inserting the probe in a thin plastic box filled with tissue-equivalent liquid, with the plastic box …
