Reply： Yes, Output power from each primary coil is 5 watts.The max output power is 5W. 3 The transfer system includes only single primary and secondary coils. This includes charging systems that may have multiple primary coils and clients that are able to detect and allow coupling only between individual pairs of coils. Reply： Yes, EUT has one primary coils, but each coil can only correspond to one client 4 Client device is placed directly in contact with the transmitter. Reply： Yes, The client device needs to be in contact with the transmitter base, and the contact distance is less than 10mm. 5 Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion). Reply： Yes, EUT is mobile device 6 The aggregate H-field strengths at 15 cm surrounding the device and 20 cm above the top surface from all simultaneous transmitting coils are demonstrated to be less than 50% of the MPE limit. Reply： Yes, RF Exposure Evaluation report test result meets this Limt.Please refer to the RF exposure Evaluation report. If you have any question or concerns, pls. contact us.

1 / 10 EUT Specification FCC ID: 2BAN4DKWL002 Characteristics Description Product Name Wireless charger Model number DK-WL-002 Power Supply 5Vdc from AC/DC Adapter（Provided by the laboratory） Operating Frequency Range 110-205KHz Modulation Technique ASK Antenna Type Induction coil Device category Portable (<20cm separation) Mobile (>20cm separation) Others ___ Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm2) Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Evaluation applied MPE Evaluation SAR Evaluation Applicable Standard: FCC Part 1(1.1310) ,Part 2(2.1091) and KDB 680106 D01 RF Exposure Wireless Charging Apps v03 Applicable Requirement: Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These categories are fixed installation, mobile, and portable and are defined as follows: 2 / 10 Fixed Installations: fixed location means that the device, including its antenna, is physically secured at a permanent location and is not able to be easily moved to another location. Additionally, distance to humans from the antenna is maintained to at least 2 meters. Mobile Devices: a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to be generally used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. Transmitters designed to be used by consumers or workers that can be easily re-located, such as a wireless modem operating in a laptop computer, are considered mobile devices if they meet the 20 centimeter separation requirement. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091. Portable Devices: a portable device 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 device requirements are found in Section 2.1093 of the FCC's Rules (47 CFR§2.1093). The FCC also categorizes the use of the device as based upon the user’s awareness and ability to exercise control over his or her exposure. The two categories defined are Occupational/ Controlled Exposure and General Population/Uncontrolled Exposure. These two categories are defined as follows: Occupational/controlled exposure limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. Limits for occupational/controlled exposure also apply in situations when a person is transient through a location where occupational/controlled limits apply provided he or she is made aware of the potential for exposure. The phrase fully aware in the context of applying these exposure limits means that an exposed person has received written and/or verbal information fully explaining the potential for RF exposure resulting from his or her employment. With the exception oftransient persons, this phrase also means that an exposed person has received appropriate training regarding work practices relating to controlling or mitigating his or her exposure. Such training is not required for transient persons, but they must receive written and/or verbal information and notification (for example, using signs) concerning their exposure potential and appropriate means available to mitigate their exposure. The phrase exercise control means that an exposed person is allowed to and knows how to reduce or avoid exposure by administrative or engineering controls and work practices, such as use of personal protective equipment or time averaging of exposure. General population/uncontrolled exposure limits apply in situations in which the general public may be exposed, or in which persons who are 3 / 10 exposed as a consequence of their employment may not be fully aware of the potential for exposure or cannot exercise control over their exposure. Licensees and applicants are responsible for compliance with both the occupational/controlled exposure limits and the general population/uncontrolled exposure limits as they apply to transmitters under their jurisdiction. Licensees and applicants should be aware that the occupational/controlled exposure limits apply especially in situations where workers may have access to areas in very close proximity to antennas and access to the general public may be restricted. In lieu of evaluation with the general population/uncontrolled exposure limits, amateur licensees authorized under part 97 of this chapter and members of his or her immediate household may be evaluated with respect to the occupational/controlled exposure limits in this section, provided appropriate training and information has been provided to the amateur licensee and members of his/her household. Other nearby persons who are not members of the amateur licensee's household must be evaluated with respect to the general population/uncontrolled exposure limits. Test Setup Block 4 / 10 Test Procedure for mobile device 1.Connect the EUT and equipment as above diagram of test configuration. 2.EUT was placed on a table, and the measure probe was placed at a measurement distance of 15cm from the EUT to the center of the probe. 3.Power on the measuring probe, the EUT was set at the maximum field strength emission state. 4.The EUT was put in different directions (Left, Right, Front, Rear, Top and Bottom) toward to the measure probe. The distance from the top of the EUT to the probe is 20CM, and the distance from other directions is 15cm.Measure the value of field strength. 5.Record the worst data of the different directions. Test Procedure for protable device 1.EUT was placed on a table, and the measure probe was placed at a measurement distance of 0~10cm from the EUT to the…
