Toxic and harmful substances I.Warning 1. The energy storage power supply needs to be stored in a dry envir onment. The correct storage method can prolong the service life of th e energy storage power supply. 2. If the product is not used for a long time, please charge and dischar ge the product every 3 months to improve the service life of the produ ct cell. 3. Do not store the product in a place where the temperature is too hig h or too low. Too high or too low ambient temperature will shorten the service life of electronic products and seriously damage the product shell. 4. Do not wipe the product with corrosive chemical solvents. The appe arance stains can be wiped with a cotton swab dipped with a small am ount of anhydrous alcohol. 5. The product must be handled carefully when being us and please do not fall or disassemble it violently. 6. There is high voltage in this product. Please do not disassemble it by yourself to avoid safety accidents. 7. This product will not be warranted if you disassemble it by yourself. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interf erence to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to w hich the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help.

Note 2: For the applicable limit, see FCC 1.1310, 680106 D01 RF Exposure Wireless Charging Apps v03r01. Note 3: Emissions between 100 kHz to 300 kHz should be assessed versus the limits at 300 kHz in Table 1 of Section 1.1310: 614 V/m and 1.63A/m. A KDB inquiry is required to determine the applicable exposure limits below 100 kHz. Page 5 of 12 Report No.: HK2211105039-2E 4. TEST PROCEDURE a. For devices designed for typical desktop applications, such a wireless charging pads, RF exposure evaluation should be conducted assuming a user separation distance 20cm. E and H field strength measurements or numerical modeling may be used to demonstrate compliance. Measurements should be made from all sides and the top of the primary/client pair, with the 0-20 cm measured from the center of the probe(s) to the edge of the device. 4.1 Test Setup 4.2 Result of Maximum Permissible Exposure Page 6 of 12 Report No.: HK2211105039-2E For Full load mode: H-Field Strength at 0-20 cm from the edges surrounding the EUT (A/m) Measuring distance (cm) Field strength Test Position A Test Position B Test Position C Test Positio n D Test Position E Test Position F Limits (A/m) 0 uT 1.543 1.504 1.505 1.460 1.522 1.547 / A/m 1.234 1.203 1.204 1.168 1.217 1.237 1.63 2 uT 1.443 1.440 1.434 1.387 1.420 1.332 / A/m 1.154 1.152 1.147 1.110 1.136 1.065 1.63 4 uT 1.264 1.207 1.312 1.309 1.247 1.209 / A/m 1.011 0.966 1.049 1.047 0.998 0.968 1.63 6 uT 1.143 1.120 1.194 1.219 1.185 1.195 / A/m 0.914 0.896 0.955 0.975 0.948 0.956 1.63 8 uT 1.094 1.050 1.045 1.089 1.073 1.104 / A/m 0.876 0.840 0.836 0.871 0.858 0.883 1.63 10 uT 0.991 0.996 1.054 0.996 0.968 0.982 / A/m 0.793 0.797 0.843 0.797 0.774 0.785 1.63 12 uT 0.925 0.855 0.834 0.887 0.858 0.812 / A/m 0.740 0.684 0.667 0.710 0.686 0.649 1.63 14 uT 0.754 0.794 0.817 0.764 0.784 0.823 / A/m 0.603 0.635 0.654 0.611 0.627 0.658 1.63 16 uT 0.670 0.709 0.726 0.681 0.679 0.712 / A/m 0.536 0.567 0.581 0.545 0.543 0.569 1.63 18 uT 0.651 0.619 0.559 0.657 0.575 0.599 / A/m 0.521 0.495 0.447 0.526 0.460 0.479 1.63 20 uT 0.375 0.382 0.465 0.462 0.411 0.386 / A/m 0.300 0.306 0.372 0.369 0.329 0.309 1.63 Note.
