Description of Test Mode To investigate the maximum EMI emission characteristics generates from EUT, the test system was pre-scanning tested base on the consideration of following EUT operation mode or test configuration mode which possible have effect on EMI emission level. Each of these EUT operation mode(s) or test configuration mode(s) mentioned follow was evaluated respectively. Test Mode Charging & Playing mode Transmitting mode Remark Description Keep the EUT in Charging& Playing mode Keep the EUT in Transmitting mode with worst case data rate GFSK(Mbps) is the worst case mode Remark: The sample was placed.8m above the ground plane of 3m chamber. Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating the turntable, varying antenna height from m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. Tel: (86)-755-23498786 Fax: (86)-755-2976525 www.ata-test.com

Test Procedure ) The EUT was placed on the top of a rotating table.8 meters above the ground at a 3 meter semi-anechoic camber. The table was rotated 36 degrees to determine the position of the highest radiation. 2) The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top of a variable-height antenna tower. 3) The antenna height is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set Tel: (86)-755-23498786 Fax: (86)-755-2976525 www.ata-test.com

Report No.: T479F Page: 47 of 52 to make the measurement. 4) For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from meter to 4 meters and the rotatable table was turned from degrees to 36 degrees to find the maximum reading. 5) The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. Peak value: RBW=MHz, VBW=3MHz; verage value: RBW=MHz, VBW=Hz; QP Value: RBW=2kHz, VBW=3kHz 6) If the emission level of the EUT in peak mode was db lower than the limit specified, then testing could be stopped and the peak values of the EUT would be reported. Otherwise the emissions that did not have db margin would be re-tested one by one using peak, quasi-peak or average method as specified and then reported in a data sheet. 4.4. Test Data Remark:. During the test, pre-scan the GFSK, π/4-dqpsk, 8-DPSK modulation, and found the GFSK modulation is the worst case. 2. Pre-scan all kind of the place mode (X-axis, Y-axis, Z-axis), and found the Y-axis is the worst case. 3. 9 khz to 3 MHz is noise floor, so only shows the data of above 3MHz in this report.
