SS WI R E L E S S E A R B U D S i A P REGULATORY NOTICE This equipment has been tested and found to comply with the limits for a Class B digital devi ce, pursuant to part 15 of the FCC Rules. These limits are designed to provi de reasonable protec�on against harmful interference in a residen�al installa�on. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruc�ons, may cause harm ful interference to radio communica�ons. However, there is no guarantee that interference will not occur in a par�cular installa�on. If this equipment does cause harmful interference to radio or televi sion recep�on, 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 ante nna. • Increase the separa�on 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. Changes or modifica�ons not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This devi ce complies with Part 15 of the FCC Rules. Opera�on is subject to the following two condi�ons: (1) this devi ce may not cause harmful interference, and (2) this devi ce must accept any interference received, including interference that may cause undesired opera�on. This equipment complies with FCC RF radia�on exposure limits set forth for an uncontrolled envi ronment. This devi ce and its antenna must not be located or operated in conjunc�on with any other antenna or transmi�er. iTECH ® A P Earbuds Touchpad Earbuds Charging Case withUSB charging port Wireless Charging Area (rear of case) OPERATING INSTRUCTIONS Fully charge your device before using.

Standalone SAR test exclusion considerations Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. These test exclusion conditions are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions. The minimum test separation distance defined in 4.1 f) is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander. To qualify for SAR test exclusion, the test separation distances applied must be fully explained and justified, typically in the SAR measurement or SAR analysis report, by the operating configurations and exposure conditions of the transmitter and applicable host platform requirements, according to the required published RF exposure KDB procedures. When no other RF exposure testing or reporting are required, a statement of justification and compliance must be included in the equipment approval, in lieu of the SAR report, to qualify for SAR test exclusion. When required, the device specific conditions described in the other published RF exposure KDB procedures must be satisfied before applying these SAR test exclusion provisions. a) For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g extremity SAR, where  f (GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation  The result is rounded to one decimal place for comparison  The values 3.0 and 7.5 are referred to as numeric thresholds in step b) below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm, and for transmission frequencies betwe…
