The above equipment was tested by A Test Lab Techno Corp. For compliance with the requirements set forth in 47
CFR § 2.1093. The results of testing in this report apply only to the product/system, which was tested. Other similar
equipment will not necessarily produce the same results due to production tolerance and measurement uncertainties.

SAR Test Exclusion
As RF exposure evaluation of portable device, SAR test is not required when the evaluation results. According to
KDB 447498 4.3.1, unless excluded by specific FCC test procedures, portable devices shall include SAR data for
equipment approval. SAR test necessity will be based on the exclusion result.
The test exclusion refers KDB 447498 as below:
≤50mm:
[(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
>50mm and <200mm:
a) [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50 mm)·( f(MHz)/150)]
mW, at 100 MHz to 1500 MHz
b) [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50 mm)·10] mW at > 1500
MHz and ≤ 6 GHz

Exclusion Considerations: Body SAR is not required
Note: 1. Calculated Value include string "mW",that is mean through compare output power with threshold, if the
output power more than threshold value the SAR test should be perform. Otherwise, the SAR test could
be exempt. (> 50mm)
2. Calculated Value only include number format, that is mean through compare output power with threshold,
if the Calculated value more than 3, the SAR test should be perform. Otherwise, the SAR test could be
exempt. (<50mm)
3. When an antenna qualifies for the standalone SAR test exclusion of KDB 447498 section 4.3.1 and also
transmits simultaneously with other antennas, the standalone SAR value must be estimated according to
KDB 447498 section "4.3.2. Simultaneous transmission SAR test exclusion considerations b) ".
4. We used highest frequency and power,that result should be evaluated the worst case.
5. Power and distance are rounded to the nearest mW and mm before calculation.
6. The result is rounded to one decimal place for comparison.
7. We use a minimum distance of 5mm for bluetooth function.
