A: For all of the headphone products, they need a period of use to get better sound quality. Some components, such as transistors, integrated circuits, and capacitors, are inherently unstable in electrical parameters and can be stabilized after a period of use. Q: Why cannot synchronize the volume? AOur products are mainly compatible with iPhone, Samsung, and other mainstream mobile phones,they may not be able to adapt to all computers, because there are too many Android systems, our headphones may not match all types of Android systems. If the volume cannot be synchronized, it needed to adjust it manually from your phone and computer. Q: How to keep clear calls? A: When using with a phone call, please turn the volume to the maximum to avoid making calls in noisy environments, such as subways and buses. These places will affect the signal connection and stability of the earbuds. Never disassemble or modify your earphone for any reasons to avoid any damages and danger. - Do not store the earphone in extreme temperature(under 0 or over 45). - Do not use this earphone during a thunderstorm to avoid irregular function and increased risk of electricshock. - Do not use harsh chemicals or strong detergents to clean the earbuds. - Keep the earbuds dry Maintenance: 1. The Reasons of our products has a battery inside it, also the battery itself has power consumption issue, so please make sure that the last charge is harged once a week in order to prevent low battery power caused by the protection plate self-protection.

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 Exclusion Threshold condition, listed below, is satisfied. 4.1.2 Limits 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 f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 17 The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is≤50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20200400315E-02 Page: 6 of 6 4…
