Use, Maintenance, and After-Sales Service (1) Proper Wearing and Use � •Applicable Scenarios: Regular cycling, skateboarding, unicycling, and other common sports where wearing a helmet is required. •Non-Applicable Scenarios: This product is not suitable for extreme sports or other high-speed or high-risk activities. •Proper Helmet Wearing: ① The helmet should be worn level, with the front edge positioned appropriately above the forehead. ② Adjust the head circumference system and chin strap to ensure a secure fit without excessive pressure. ③ The helmet should not move noticeably when shaking your head. ④ Before each ride, please check the helmet shell, retention system, and electronic functions to ensure they are functioning properly. Safety Notice: This helmet has been certified in accordance with EN 1078�2012+A1�2012 and holds CPC certification. It meets the essential health and safety requirements (WGSA of Regulation (EU) 2016/425) as well as the U.S. CPSC safety standard for bicycle helmets for persons aged 5 years and older. However, no helmet can provide complete protection in all accidents. This product is designed to reduce the risk of head injuries but cannot guarantee the prevention of all injuries. (2) Cautions and Warnings •This helmet contains electronic components and provides limited splash resistance. Please do not use it for prolonged riding in rainy conditions. •After exposure to rain, water droplets may appear inside the rear warning light cover. Place the helmet in a well-ventilated area for 1–2 days, and the moisture will dissipate naturally. •This helmet contains a battery. Battery capacity may vary with temperature. When used in low-temperature environments or below 0°C, the operat- ing time may be reduced to varying degrees. •To maintain battery lifespan, if the helmet is to be stored for an extended period (over 3 months), it is recommended to fully charge the helmet before storage and recharge it every 3–6 months. Important Safety Warning: If the helmet experiences a severe impact, fall, or traffic accident during use, internal cushioning materials may be damaged even if no visible damage is present. Protective performance can no longer be guaranteed. Discontinue use immediately and replace the helmet with a new one. (3) Cleaning and Maintenance Instructions � •Store the helmet properly. Clean it with clean water only. Do not use alcohol, gasoline, organic solvents, or corrosive liquids such as acids or alkalis. Avoid impacts to the helmet. •Do not modify the structure of the helmet. Drilling holes in the shell or altering the internal foam liner is strictly prohibited, as this may impair its shock-absorption and penetration-resistance performance. •Under normal use and proper maintenance, the recommended service life of the helmet is 3–5 years. (4) Technical Specifications •Charging Port: Type-C USB •Electrical Rating: DC 5V / 1A •Charging Time: 1.5 hours •Waterproof Rating: IPX45 •Operating Time: Up to approximately 28 h…
