High temperatures can shorten the lifespan of electronic components, damage the battery, and deform some plastic parts. ·Do not place the product in excessively cold environments to avoid damaging the internal circuit board. ·Do not attempt to disassemble the product. This may damage the product if not done by a professional. ·Do not drop, subject to strong vibrations, or impacts from hard objects to avoid damaging the internal circuitry. ·Do not use harsh chemicals or cleaning agents to clean the headphones. ·Do not scratch the product surface with sharp objects to avoid damaging the casing and affecting its appearance. Maintenance and Repair 13 ·Please store the headsets in a cool, dry place at room temperature. Prolonged exposure to sunlight, humidity, sealed environments, and high temperatures will accelerate oxidation and material wear. ·After use, if there are sweat stains, oil stains, or other liquids, wipe them clean with a cotton cloth dampened with diluted alcohol and store them in a ventilated place to prevent the ear tips from staining, deforming, hardening, and decomposing, thus shortening their lifespan. ·When not in use, please place the headsets in the headset case or hang them on a headphone stand to avoid damaging the ear tips. ·Avoid excessive stretching of the ear tips, as this will deform them and affect wearing comfort. ·Please clean them regularly, using a soft cloth or small brush to gently wipe away liquids and dirt from the ear tips. ·Proper maintenance will keep the ear tips in good condition, extend their lifespan, and improve sound quality and comfort.

FCC 47CFR §2.1093 REQUIREMENT 2.1 TEST STANDARDS Follow the maximum permissible exposure (MPE) limits specified in 447498 D04 Interim General Radio Frequency Exposure Guidelines v01. The gain of the antenna used in the product was extracted from the supplied antenna data sheet and the maximum total power input to the antenna was also measured. Calculate the distance from the product to the MPE limit by the formula. 2.2 LIMIT For single RF sources (i.e., any single fixed RF source, mobile device, or portable device, as defined in paragraph (b)(2) of this section): A single RF source is exempt if: (A) The available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption may not be used in conjunction with other exemption criteria other than those in paragraph (b)(3)(ii)(A) of Part 1.1307. Medical implant devices may only use this exemption and that in paragraph (b)(3)(ii)(A); (B) Or the available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is less than or equal to the threshold Pth (mW) described in the following formula. This method shall only be used at separation distances (cm) from 0.5 centimeters to 40 centimeters and at frequencies from 0.3 GHz to 6 GHz (inclusive). Pth is given by: Page 7 of 9 Report No.:STS2510211H01 (C) Or using below table and the minimum separation distance (R in meters) from the body of a nearby person for the frequency (f in MHz) at which the source operates, the ERP (watts) is no more than the calculated value prescribed for that frequency. For the exemption in Table 1 to apply, R must be at least λ/2π, where λ is the free-space operating wavelength in meters. If the ERP of a single RF source is not easily obtained, then the available maximum time-averaged power may be used in lieu of ERP if the physical dimensions of the radiating structure(s) do not exceed the electrical length of λ/4 or if the antenna gain is less than that of a half-wave dipole (1.64 linear value).
