                            1. The RF exposure test was performed on 360 degree
                               turn table in anechoic chamber.
                            2. The measurement probe was placed at test distance
                               (15cm) which is between the edge of the charger and
                               the geometric centre of probe.
                            3. The turn table was rotated 360d degree to search of
     Test Procedure:
                               highest strength.
                            4. The highest emission level was recorded and
                               compared with limit as soon as measurement of each
                               points (A, B, C, D, E) were completed.
                            5. The EUT were measured according to the dictates of
