Page 1 of 7 FCC ID: 2A93X-V7 R F Exposure Evaluation 1 Measuring Standard KDB 680106 RF Exposure Wireless Charging Apps v03r01 2 Requirements According to the item 5 of KDB 680106 v03r01: Inductive wireless power transfer applications that meet all of the following requirements are excluded from submitting an RF exposure evaluation. (1)Power transfer frequency is less than 1MHz. (2) O utput power from each primary coil is less than or equal to 15 watts. (3)The system may consist of more than one source primary coils, charging one or more clients. If more than one primary coil is present, the coil pairs may be powered on at the same time. (4) Client device is placed directly in contact with the transmitter. (5) Mob ile exposure conditions only (portable exposure conditions are not covered by this exclusion). (6) T he aggregate H-field strengths anywhere at or beyond 15 cm surrounding the device, and 20 cm away from the surface from all coils that by design can simultaneously transmit, and while those c oils are simultaneously energized, are demonstrated to be less than 50% of the applicable MPE limit. Remark: Meet all the above requirements. 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) Page 2 of 7 FCC ID: 2A93X-V7 3 Test Setup 4 Test Procedure 1) The RF exposure test was performed in anechoic chamber. 2) The measurement probe was placed at test distance (15 cm from all sides and 20 cm from the top) which is between the edge of the charger and the geometric center of probe. 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 D01v03. Remark：The EUT’s test position A, B, C, D and E is valid for the E and H field measurements. 5 Description of the test mode Equipment under test was operated during the measurement under the following conditions: Test Mode Description Mode 1 AC Adapter + EUT + Mobile phone+ Earphone+ Watch Record Mode 2 AC Adapter + EUT + Mobile phone+ Earphone Pre-tested Mode 3 AC Adapter + EUT + Mobile phone+Watch Pre-tested Mode 4 AC Adapter + EUT + Earphone +Watch Pre-tested Mode 5 AC Adapter + EUT + Mobile phone Pre-tested Mode 6 AC Adapter + EUT + Earphone Pre-tested Mode 7 AC Adapter + EUT + Watch Pre-tested Mode 8 Test the EUT in idle mode.
