For areas where there are regulations on recycling and disposal of used batteries, please comply with the related local regulations and help protect the environment. 2. Do not short circuit the batteries. When a metallic object (such as keys, jewelry, wires, coins or other conductive materials) inadvertently connects the positive and negative terminals of the batteries, a short circuit will occur. A short circuit may damage the battery or the connector, and may result in property damage or personal injury. Please put charged batteries in an appropriate place, paying particular attention to those in your pocket, wallet or other place where there might be metal objects. 3. Do not throw batteries into a fire or place them in a high temperature environment so as to avoid battery leakage, overheating, explosion or fire. 4. Do not disassemble, solder or modify the batteries; do not put the battery in locations subject to strong mechanical impact or hit the battery with a hard object, which will cause battery leakage, overheating, explosion or fire. III.Safety Precautions for Battery Use Comply with all related regulations and do not use this product in areas where blasting is in progress. 9. Accessories and batteries: Use only our approved accessories and batteries as other accessories and batteries may damage the product and be dangerous. 10. Connecting to other devices: When connecting the product to other devices, read the instructions of the other device for detailed safety instructions. Do not connect incompatible products. -4- 5. It is strictly prohibited to disassemble, crush, heat or burn built-in batteries; sharp objects, screwdrivers, etc. are forbidden from piercing or prying open the batteries. These actions may cause the battery to ignite or burn. 6. If a battery's electrolyte gets into your eyes, there is a risk of blindness. If the electrolyte is accidentally splashed into your eyes, do not rub your eyes. Immediately flush thoroughly with clean water and contact a hospital for treatment; in case a weak battery's electrolyte comes into contact with skin or clothes, wash immediately with soap and clean water, and consult a doctor immediately if necessary. 7. Do not use the battery for other purposes. Never use a damaged charger or battery. In case of overheating, discoloration, deformation, bulging, leakage and other anomalies that occur when batteries are in use, being charged or in storage, please stop using and replace so as to avoid safety issues. 8. Batteries are not waterproof. Do not use or charge a battery in the kitchen, bathroom or other hot and humid location. 9. When a battery is being charged, its temperature will rise. Please do not put the battery and combustibles (e.g.: bedding, clothing, books, etc.) together in case of fire. IV.Warning and Important Tips (For Helmets) 1. This helmet is designed especially for use with bicycles. Do not use it with motorcycles, motor- mounted bicycles or other sports equipment or during other sporting activities. 2. No safety helmet can completely avoid all unforseen impacts. Yet to achieve the …

RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Bling Helmet Model Name BH51M Neo, BH51T Neo, BH51M, BH51T FCC ID 2AEKFBH51XX 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 BT(BLE) P t =0.450dBm=1.11mW 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=(1.11mW /5mm) .[√2.402(GHz)]= 0.34<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. BT(BR&EDR) P t =7.418dBm=5.52mW 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=(5.52mW /5mm) .[√2.402(GHz)]= 1.71<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. Note: The BLE and BR&EDR can not transmit simultaneously. 4. CONCLUSION The SAR evaluation is not required.

The GFSK modulation is the worst case and recorded in the report. Report No.: AGC01993210403FE03 Page 59 of 78 11. NUMBER OF HOPPING FREQUENCY 11.1. MEASUREMENT PROCEDURE The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings: 1. Span: The frequency band of operation. Depending on the number of channels the device supports, it may be necessary to divide the frequency range of operation across multiple spans, to allow the individual channels to be clearly seen. 2. RBW: To identify clearly the individual channels, set the RBW to less than 30% of the channel spacing or the 20 dB bandwidth, whichever is smaller. 3. VBW ≥ RBW. Sweep: Auto. Detector function: Peak. Trace: Max hold. 4. Allow the trace to stabilize. 11.2. TEST SETUP (BLOCK DIAGRAM OF CONFIGURATION) Same as described in section 8.2 11.3. MEASUREMENT EQUIPMENT USED The same as described in section 6 11.4. LIMITS AND MEASUREMENT RESULT Test Data of Number of Hopping Frequency Test Mode Number of Hopping Frequency Limits Pass or Fail GFSK Hopping 79 >=15 Pass Test Graphs of Number of Hopping Frequency Test_Graph_BR_HOP_ANT1_NA_1Mbps_Number of Hopping Note: The GFSK modulation is the worst case and recorded in the report. Report No.: AGC01993210403FE03 Page 60 of 78 12. TIME OF OCCUPANCY (DWELL TIME) 12.1. MEASUREMENT PROCEDURE The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings: 1. Span: Zero span, centered on a hopping channel. 2. RBW shall be≤channel spacing and where possible RBW should be set >> 1 / T, where T is the expected dwell time per channel. 3. Sweep: As necessary to capture the entire dwell time per hopping channel; where possible use a video trigger and trigger delay so that the transmitted signal starts a little to the right of the start of the plot. The trigger level might need slight adjustment to prevent triggering when the system hops on an adjacent channel; a second plot might be needed with a longer sweep time to show two successive hops on a channel. 4. Detector function: Peak. Trace: Max hold. 5. Use the marker-delta function to determine the transmit time per hop. 6. Repeat the measurement using a longer sweep time to determine the number of hops over the period specified in the requirements. The sweep time shall be equal to, or less than, the period specified in the requirements. Determine the number of hops over the sweep time and calculate the total number of hops in the period specified in the requirements, using the following equation: (Number of hops in the period specified in the requirements) = (number of hops on spectrum analyzer) × (period specified in the requirements / analyzer sweep time) 7. The average time of occupancy is calculated from the transmit time per hop multiplied by the number of hops in the period specified in the requirements. 12.2.

FREQUENCY SEPARATION 13.1. MEASUREMENT PROCEDURE The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings: 1. Span: Wide enough to capture the peaks of two adjacent channels. 2. RBW: Start with the RBW set to approximately 30% of the channel spacing; adjust as necessary to best identify the center of each individual channel. 3. Video (or average) bandwidth (VBW) ≥ RBW. 4. Sweep: Auto. e) Detector function: Peak. f) Trace: Max hold. g) Allow the trace to stabilize. Use the marker-delta function to determine the separation between the peaks of the adjacent channels. 13.2. TEST SETUP (BLOCK DIAGRAM OF CONFIGURATION) Same as described in section 6.2 13.3.
