3. Method of measurement

3.1. Applicable Standard
According to §1.1307(b)(1), systems operating under the provisions of this section shall be
operated in a manner that ensures that the public is not exposed to radio frequency energy level
in excess of the Commission’s guidelines.
According to §1.1310 and §2.1093 RF exposure is calculated.
According KDB680106 D01v02: RF Exposure Wireless Charging Apps v03.


3.2. Block diagram of test setup




Note: Due to installation limitations no tests from the underside of the charging device (Test
Position F) are required.


3.3. Test Procedure
a) The RF exposure test was performed in shielded chamber.

b) The measurement probe was placed at test distance (15cm) which is between the edge of the
   charger and the geometric centre of probe.

c) The measurement probe used to search of highest strength.

d) The highest emission level was recorded and compared with limit as soon as measurement of
   each points (A, B, C, D, E) were completed.

e) The EUT were measured according to the dictates of KDB 680106D01v03.
