7.4 Test Procedure

1. 1The EUT is placed on a turntable. For below 1GHz, the EUT is 0.8m above ground plane;
For above1GHz, the EUT is 1.5m above ground plane.
2. The turntable shall be rotated for 360 degrees to determine the position of maximum emission level.
3. EUT is set 3m away from the receiving antenna, which is moved from 1m to 4m to find out the
maximum emissions. The spectrum was investigated from the lowest radio frequency signal
generated in the device, without going below 9 kHz, up to the tenth harmonic of the highest
fundamental frequency or to 40 GHz, whichever is lower.
4. Maximum procedure was performed on the six highest emissions to ensure EUT compliance.
5. And also, each emission was to be maximized by changing the polarization of receiving antenna
both horizontal and vertical.
6. Repeat above procedures until the measurements for all frequencies are complete.
7. The radiation measurements are tested under 3-axes(X,Y,Z) position(X denotes lying on the table,
Y denotes side stand and Z denotes vertical stand), After pre-test, It was found that the worse
radiation emission was get at the X position. So the data shown was the X position only.

11 Human Exposure
Test Requirement: FCC Part 1.1307
Evaluation Method: FCC Part2.1093 & 447498 D01 General RF Exposure Guidance v06

11.1 Requirements

1) The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances
≤50 mm are determined by:
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√
f(GHz)] ≤3.0 for 1-g SAR and ≤7.5 for 10-g extremity SAR where

1. f(GHz) is the RF channel transmit frequency in GHz
2. Power and distance are rounded to the nearest mW and mm before calculation
3. The result is rounded to one decimal place for comparison
The test exclusions are applicable only when the minimum test separation distance is ≤50 mm and for
transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is
< 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
