Bay Area Compliance Laboratories Corp. (Shenzhen) Project No.: RTZ201110004-RF FCC ID : 2AX6N-CW305 1.1. Test Facility The Test site used by Bay Area Compliance Laboratories Corp. (Shenzhen) to collect test data is located on the 6/F., West Wing, Third Phase of Wanli Industrial Building, Shihua Road, Futian Free Trade Zone, Shenzhen, Guangdong, China. The test site has been approved by the FCC under the KDB 974614 D01 and is listed in the FCC Public Access Link (PAL) database, FCC Registration No.: 342867, the FCC Designation No.: CN1221. The test site has been registered with ISED Canada under ISED Canada Registration Number 3062B. 1.2. Measuring Standard FCC CFR 47 Part 1(1.1310) KDB 680106 D01 v03 1.3. Requirements The EUT does comply with item 5(b) of KDB 680106 D01 v03 1) Power transfer frequency is less than 1MHz 2) Output power from each primary coil is less than or equal to 15 watts. 3) The transfer system includes only single primary and secondary coils. This includes charging systems that may have multiple primary coils and clients that able to detect and allow coupling only between individual pair of coils. 4) Client device is inserted in or placed directly in contact with the transmitter. 5) Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion) 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. Bay Area Compliance Laboratories Corp. (Shenzhen) Project No.: RTZ201110004-RF 1.4. Test Configuration 1) The field strength of both E-field and H-field was measured at 15cm using the equipment list above for determining compliance with the MPE requirements of FCC Part 1.1310. 2) The RF power density was measured at Under maximum load test 3) Maximum E-field and H-field measurements were made 15cm from each side of the EUT. Along the side of the EUT and still 15cm away from the edge of the EUT, the field probes were positioned at the location where there is maximum field strength. The maximum E-field and H-field is reported below. 4) This device uses a wireless charging circuit for power transfer operating at the frequency of 110–205kHz. Thus, the 300kHz limits were used: E-field Limit = 614 (V/m); H-field limit = 1.63 (A/m). Bay Area Compliance Laboratories Corp. (Shenzhen) Project No.: RTZ201110004-RF 1.5. Test Procedure 1) The RF exposure test was performed in anechoic chamber. 2) The aggregate H-field strengths at 15 cm surrounding the device and 20 cm above the top surface 3) The highest emission level was recorded and compared with limit as soon as measurement of each points (A, B, C, D, E) were completed. 4) The EUT was measured according to the dictates of KDB 680106 D01 v03. Remark: The EUT’s test position A, B, C, D, and E is valid for the E and H field measurements. 1.6. Test Setup Bay Area Compliance Laboratories Corp. (Shenzhen) Project No.: RTZ201110004-RF 1.7. Limits Remark: 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 1.63 A/m 1.8.
