Technical Specifications Notes: The above data is measured by LIVALL in a controlled environment, with room temperature at 25°C and specific light patterns. The actual data might be different according to the environment. Model:C20 Charging port : Magnetic USB Battery : 3.7V/455mAh Waterproof class : IPX4 Temperature: Storage Temperature: -20°C ~45°C. Temperature for use: 0°C~40°C. Temperature while charging: 0°C~40°C. Electricity parameter : DC 5V/1A Charging time : 3-4 hours Battery life : about. 26-36hrs for lighting all the time Performance standards: USA: CPSC1203:1998, FCC Part 15 Rules Europe: EN 1078: 2012+A1:2012 V. Considerations 1. The helmet contains electronic parts inside. Please do not take a long ride in the rain although the helmet can prevent the rain from splashing. 2. After the helmet gets wet in the rain, the water droplets might occur in the chimney of tail LED lights. The water droplets will disappear when you put the helmet under the ventilation environment for 1-2 days. 3. The helmet contains the battery of 3.7V/455mAh. The battery capacity varies with temperature change. The battery life can decay when the helmet is used at low temperatures or below Zero degrees Celsius. 4. Trying to clean the golden colour contacts of the charging plug sheet with metal or hard tools such as blades or tweezers is strictly forbidden. Please use cotton swabs with clean water or alcohol in case of cleaning. Please make sure the charging plug is clean and try while charging the helmet. 5. If the electronic functions do not work, please charge the helmet for 3 hours and then check if it works normally. 7 VI. Instructions for Use and Care 1.

RF Exposure Info

RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Smart Commuter Helmet C20 Model Name C20, N20, A20, C21, C22, C23, SH50 SOS, SH50 FCC ID 2AEKF-C20 2. EVALUATION METHOD According to 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 f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 3. CALCULATION P t =-3.543dBm=0.44mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(0.44mW /5mm) .[√2.440GHz)]= 0.14<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
