Report No: SSP24070377-1E FCC ID:2BKID-CAW52 Annex of Test Report Annex D. Label and Information FCC Label Sample FCC Label Specifications Text is Black in color and is justified. Labels are printed in indelible ink on permanent adhesive backing or silk-screened onto the EUT or shall be affixed at a conspicuous location on the EUT. Where the EUT is constructed in two or more sections connected by wires and marketed together, the above statement is required to be affixed only to the main control unit. When the EUT is so small or for such use that it is not practicable to place the statement on it, the above information shall be placed in a prominent location in the instruction manual or pamphlet supplied to the user or, alternatively, shall be placed on the container in which the device is marketed.

FCC ID:2BKID-CAW52 RF Exposure Evaluation Product Name: Wireless Charging Pad Model No.: CAW52 Transmitting mode Keep the EUT in continuously wireless charging mode Power supply: Input: DC 9V/2A Wireless charging Output:10W (MAX) Test Modes: TM1 Wireless charging 10W Record Note: All modes have been tested and only the worst mode (Wireless Charging 10W) data is represented in the report. 1 Test Instruments list Software name Manufacturer Model Version EHP200-TS Narda EHP-200A Rel 1.95 Item Equipment No. Equipment name Manufacturer Model Serial No. Calibration date Due date 1 HB-E073 Electric and Magnetic Field Analyzer Narda EHP-200 A 180ZX1101 3 2024-05-21 2025-05-20 Note: the calibration interval of the above test instruments is 12 months and the calibrations are traceable to international system unit (SI). 2 Test Setup 3 Test Procedure 1) The RF exposure test was performed in anechoic chamber. 2) E and H-field measurements should be made with the center of the probe at a distance of 20m surrounding the device and 20 cm above the top surface of the primary/client pair. These measurements should be repeated for three different client battery levels, 1%, 50%, and 99%. 3) The highest emission level was recorded and compared with limit as soon as measurement of each points were completed. 4) The EUT was measured according to the dictates of KDB 680106 D01 v04. Limits The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) Limits for Maximum Permissible Exposure (MPE) 4 Measuring Standard KDB 680106 D01 Wireless Power Transfer v04r01 5 Requirements According to the item 5 of KDB 680106 D01 Wireless Power Transfer v04r01: Inductive wireless power transfer applications that meet all of the following requirements are excluded from submitting an RF exposure evaluation. (1) The power transfer frequency is below 1MHz. Yes, the device operate in the frequency range from 110.1KHz to 205KHz. (2) The output power from each transmitting element (eg., coil) is less than or equal to 15 watts. Yes, the maximum output power of the primary coil is 10W. (3) A client device providing the maximum permitted load is placed in physical contact with the transmitter (i.e., the surfaces of the transmitter and client device enclosures need to be in physical contact) Yes, the surfaces of the transmitter and client device enclosures need to be in physical contact. (4) Only § 2.1091-Mobile exposure conditions apply (i.e., this provision does not cover § 2.1093-Portable exposure conditions). Yes, this device is a Mobile device. (5) The E-field and H-field strengths, at and beyond 20 cm surrounding the device surface, are demonstrated to be less than 50% of the applicable MPE limit, per KDB 447498, Table 1. These measurements shall be taken along the principal axes of the device, with one axis oriented along the direction of the estimated maximum field strength, and for three points per axis or until a 1/d (inverse distance from the emitter structure) field strength decay is observed. Symmetry considerations may be used for test reduction purposes. The device shall be operated in documented worst-case compliance scenarios (i.e., the ones that lead to the maximum field components), and while all the radiating structures (e.g., coils or antennas) that by design can simultaneously transmit are energized at their nominal maximum power. The EUT field strength levels are less 50% x MPE limit. (6) For systems with more than one radiating structure, the conditions specified in (5) must be met when the system is fully loaded (i.e., clients absorbing maximum power available), and with all the radiating structures operating at maximum power at the same time, as per design conditions. If the design allows one or more radiating structures to be powered at a higher level while other radiating structures are not powered, then those cases must be tested as well. For instance, a device may use three RF coils powered at 5 W, or one coil powered at 15 W: in this case, both scenarios shall be tested. This device has only one wireless charging coil. 6 Test Result Maximum permissible Exposure Battery levels Test sides Test distance(cm) E –field(V/m) H–field(A/m) <1% Top 20 2.471 0.322 <1% Left 20 4.252 0.220 <1% Right 20 6.345 0.478 <1% Front 20 3.674 0.186 <1% Back 20 1.733 0.135 Limit 614 1.63 50% Margin Limit 307 0.815 Maximum permissible Exposure Battery levels Test sides Test distance(cm) E –field(V/m) H–field(A/m) <50% Top 20 2.162 0.197 <50% Left 20 4.374 0.2352 <50% Right 20 6.155 0.271 <50% Front 20 3.856 0.176 <50% Back 20 1.384 0.175 Limit 614 1.63 50% Margin Limit 307 0.815 Maximum permissible Exposure Battery levels Test sides Test distance(cm) E –field(V/m) H–field(A/m) <99% Top 20 2.741 0.346 <99% Left 20 4.722 0.184 <99% Right 20 6.668 0.387 <99% Front 20 3.543 0.285 <99% Back 20 2.362 0.203 Limit 614 1.63 50% Margin Limit 307 0.815 7 Test Setup Photo
