Test Result 6.1 Test Setup Side Side 11 Side Side 55 Side Side 44 Side22 Side Side Side 66 Side Side 33 6.2 Measurement Procedure The RF exposure test was performed on 360 degree turn table in anechoic chamber. The measurement probe was placed at test distance ( 10 ㎝) which is between the edge of the charger and the geometric center of probe. The turn table was rotated 360 degree to search of highest strength. The highest emission level was recorded and compared with limit as soon as measurement of each points (Side 1 ~ 6) were completed. The EUT were measured according to the dictates of KDB 680106 D01v02. EUT Type: Refrigerator FCC ID.: BEJE18MRE07 G E T E C

The EUT does with item 5.2 of KDB 680106 D01v02 a) Power transfer frequency is less that 1 ㎒ - Power transfer(Main Carrier) frequency is fixed between 330 kHz ~ 370 kHz b) Output power from each primary coil is less than 5 watts. - The maximum field strength of fundamental : 60.81 dBµV/m at 3 m. The EIRP calculation is reference to KDB 789033 ※ EIRP[dBm] = E[dBµV/m]+20log(d[meters]) -104.77 , d = 3 m ※ 60.81 dBµV/m – 95.2 = -34.39 dBm EIRP ※ The output power from primary coil is 0.000 363 ㎽ c) 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 - The system is consists of single primary and secondary coils. d) Client device is inserted in or placed directly in contact with the transmitter - Client device(Receiver) is placed by the transmitter with a less than 10 mm gap. Refer to following photo. e) The maximum coupling surface area of the transmit(charging) device is between 60 cm2 and 400 cm2 - The shape of primary and secondary coils are same and the they are center-aligned. Maximum coupling surface area of transmitter is under 20cm2 f) Aggregate leakage fields at 10 cm surrounding the device from all simultaneous transmitting coils are demonstrated to be less than 30% of the MPE limit. - Aggregate leakage level of the system in normal operating condition at 10cm surrounding the device is under 15% of MPE limit (<0.2A/m) - 0.212 A/m (maximum measure value) < 0.486 Am (30% MPE limit) EUT Type: Refrigerator FCC ID.: BEJE18MRE07 G E T E C
