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 are designed to provide reasonable protection against harmful interf erence in a residential in stallation. This equipment generates uses and ca n radiate radio frequency energy and, if not in stalled and used in accordance with the in structions, may cause harmful interf erence to radio communica tio ns. However, there is no guarantee that inter ference will not occur in a particular in stallation. If this equipment does cause harmful interf erence to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to corr ect the interference by one or more of the following measures: ‐‐ Reori ent 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 th e receiver is connected. ‐‐ Consult the dealer or an experienced radio/TV technician for help. This device complies with part 15 of the FCC Rules. Operation is subject to th e following two conditions: (1) This device may not ca use 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: SMART EYEWEAR Model No.: TCW02 FCC ID: 2AU3D-TCW02 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.

The test exclusion threshold is 2.501 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
