Please do not use, leave or store the product in a high temperature environment. Do not throw this product into fire. Do not drop this product, place heavy objects on top of it, or give it a shock. Doing so may result in electric shock, malfunction, injuries, or smoke/fire. This product should be used away from devices that generate heat. Do not leave it in high temperature places such as in direct sunlight or in a car. It may cause heat generation and ignition. CautionFCC Warning Statement Do not use this product for any purpose other than its intended use. Do not use this product near flammable oil, chemicals or flammable substances. Do not use or store the product in a place where it is exposed to water or other liquids. This product may become hot while using the wireless charging function, but this is due to the specifications and is not a malfunction. Please note that we are not responsible for any damage, breakage, breakdown or loss of data on devices connected to this product. When using the wireless charging function, do not use a metal protective cover attached. This will activate the object detection function and prevent proper charging. Depending on the thickness of the protective cover, magnetic wireless charging may not work or charging may become slow. In this case, please remove the cover. Also, please note that wireless charging cannot be done while wearing a drop prevention ring. If the ambient temperature is high, the wireless charger will automatically limit its output to reduce heat generation, which may slow down the charging speed. This is a common phenomenon with most wireless chargers. In addition, batteries tend to deteriorate in high-temperature environments, so we recommend charging in environments below 25 degrees Celsius. This product may become hot when using the wireless charging function, but this is not a problem. This product has a built-in magnet. Do not hold credit cards or other items close to or between this product. Doing so may result in damage to the magnetism or RFID chip. This product has a built-in wireless transmitter that generates magnets and electromagnetic waves. These parts may interfere with medical devices such as pacemakers. Please consult with your doctor before use. Due to its characteristics, wire…

RF EXPOSURE EVALUATION METHOD FCC ID: 2BO4X-MB10W1C Applicable standard： In accordance with FCC 47 CFR part 2 (2.1093) this device has been defined as a portable device which is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable devices must be evaluated using the specified in FCC 47 CFR part 2 (2.1093) and ANSI/IEEEC95.1-1992. and had been tested in accordance with the measurement methods and procedures specified in IEEE 1528-2003. Per FCC KDB 447498 D01 v06, the 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances s 50 mm are determined by: SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. 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 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.

[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] * [√f(GHz)] < 3.0. 2. SAR Test Exclusion Thresholds is 3.0 for separation distance 5mm. Therefore, SAR test is not required.
