Test Result 6.1 Test Setup 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 ( 15 ㎝ and 20 cm (the top surface)) 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 ~ 5) were completed. The EUT were measured according to the dictates of KDB 680106 D01v03 GETEC-QP-28-007 (Rev.03) EUT Type: Household Refrigerator G E T E C FCC ID.: BEJA408SW19

The EUT does with item 5.2 of KDB 680106 D01v03 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 or equal to 15 watts. - The maximum field strength of fundamental : 57.51 dBV/m at 3 m. The EIRP calculation is reference to KDB 789033 ※ EIRP[dBm] = E[dBV/m]+20log(d[meters]) - 104.77 , d = 3 m ※ 57.51 dBV/m – 95.2 = -37.69 dBm EIRP ※ The output power from primary coil is 0.000 17 ㎽ 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) Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion) -None. f) The aggregate H-fields 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. - 0.414 A/m (maximum measure value) < 0.815 A/m (50% MPE limit) GETEC-QP-28-007 (Rev.03) EUT Type: Household Refrigerator G E T E C FCC ID.: BEJA408SW19

Limits for occupational/controlled exposure also apply in situations when an individual is transient through a location where occupational/controlled limits apply provided he or she is made aware of the potential for exposure. Note 2 to Table 1: General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure.
