FCC Warning Statement 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 found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits ar e 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 par ticular 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 r eceiving 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. This device complies with part 15 of the FCC Rules. Oper ation 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. The device has been evaluated to meet general RF exposure requirement.

FCC RF Exposure EUT Description: Wireless Headphones Model No.: Tommy earbuds 333, Tommy earbuds 433, Tommy Buds FCC ID : 2AXK8‐EP333 1. Limits According to KDB 447498 D01 General RF Exposure Guidance v06 The 1‐g and 10‐g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤50 mm are determined by: [(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: Result=P/D*√F F= the RF channel transmit frequency in GHz P=Maximum turn‐up power in mw D=Min. test separation distance in mm 2. Test Result of RF Exposure Evaluation 2.4G Output power （dBm ） Tune Up Power （dBm） Max Tune Up power dBm/mW Min test separatio n distance mm Result Limit SAR Test Exclusion BT ‐5.219 ‐6±1 ‐5/ 0.32 5 0.09919 3.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2009152611‐E, antenna gain=‐0.58dBi Per KDB 447498 D01, when the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine RF Exposure test exclusion. The test exclusion threshold is 0.09919 which is<= 3, RF Exposure testing is not required. Note: Exclusion Thresholds Results=[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] f(GHz) is the RF channel transmit frequency in GHz Distance=5mm
