According to KDB447498 D01 General RF Exposure Guidance V05 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 f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 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. We use 5mm as separation distance to calculate.

Access to the World 7.2 RADIO FREQUENCY TEST SETUP 2 The test site semi-anechoic chamber has met the requirement of NSA tolerance 4 dB according to the standards: ANSI C63.10. The test distance is 3m.The setup is according to the requirements in Section 13.1.4.1 of ANSI C63.10-2013 and CAN/CSA-CEI/IEC CISPR 22. Below 30MHz The EUT is placed on a turntable 0.8 meters above the ground in the chamber, 3 meter away from the antenna (loop antenna). The Antenna should be positioned with its plane vertical at the specified distance from the EUT and rotated about its vertical axis for maximum response at each azimuth about the EUT. The center of the loop shall be 1 m above the ground. For certain applications, the loop antenna plane may also need to be positioned horizontally at the specified distance from the EUT. 30GHz-1GHz The EUT is placed on a turntable 0.8 meters above the ground in the chamber, 3 meter away from the antenna. The maximal emission value is acquired by adjusting the antenna height, polarisation and turntable azimuth. Normally, the height range of antenna is 1 m to 4 m, the azimuth range of turntable is 0 to 360, and the receive antenna has two polarizations Vertical (V) and Horizontal (H). Above 1GHz The EUT is placed on a turntable 1.5 meters above the ground in the chamber, 3 meter away from the antenna. The maximal emission value is acquired by adjusting the antenna height, polarisation and turntable azimuth. Normally, the height range of antenna is 1 m to 4 m, the azimuth range of turntable is 0 to 360, and the receive antenna has two polarizations Vertical (V) and Horizontal (H).

If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. 8.4.3 Test Configuration Test according to clause 7.1 radio frequency test setup 1 8.4.4 Test Procedure The transmitter output (antenna port) was connected to the spectrum analyzer

Reference level measurement Establish a reference level by using the following procedure:

Set instrument center frequency to DTS channel center frequency. Set the span to = 1.5 times the DTS bandwidth. Set the RBW = 100 kHz. Set the VBW 3 x RBW. Set Detector = peak. Set Sweep time = auto couple. Set Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum PSD level. Note that the channel found to contain the maximum PSD level can be used to establish the reference level.

Emission level measurement Set the center frequency and span to encompass frequency range to be measured. Set the RBW = 100 kHz. Set the VBW =300 kHz. Set Detector = peak Sweep time = auto couple. Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum amplitude level. Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding restricted frequency bands) are attenuated by at least the minimum requirements . Report the three highest emissions relative to the limit. 8.4.5 Test Results TRF No.:FCC 15.247/A Page 20 of 41 Report No.: ES150929025E Ver.1.0 Test Model Test Model Access to the World PSD(Power Spectral Density ) RBW=100kHz Bluetooth 4.0 DTS Channel 0: 2402MHz Unwanted Emissions in non-restricted frequency bands Channel 0: 2402MHz Bluetooth 4.0 DTS TRF No.:FCC 15.247/A Page 21 of 41 Report No.: ES150929025E Ver.1.0 Test Model Test Model Band edge Bluetooth 4.0 DTS Channel 0: 2402MHz PSD(Power Spectral Density ) RBW=100kHz Bluetooth 4.0 DTS Channel 19: 2440MHz Access to the World TRF No.:FCC 15.247/A Page 22 of 41 Report No.: ES150929025E Ver.1.0 Test Model Test Model Unwanted Emissions In Non-Restricted Frequency Bands Channel 19: 2440MHz Bluetooth 4.0 DTS Access to the World PSD(Power Spectral Density ) RBW=100kHz Bluetooth 4.0 DTS Channel 39: 2480MHz TRF No.:FCC 15.247/A Page 23 of 41 Report No.: ES150929025E Ver.1.0 Test Model Test Model Unwanted Emissions In Non-Restricted Frequency Bands Channel 39: 2480MHz Bluetooth 4.0 DTS Access to the World Band edge Bluetooth 4.0 DTS Channel 39: 2480MHz TRF No.:FCC 15.247/A Page 24 of 41 Report No.: ES150929025E Ver.1.0 8.5 RADIATED SPURIOUS EMISSION 8.5.1 Applicable Standard Access to the World According to FCC Part 15.247(d) and 15.209 and KDB 558074 DTS 01 Meas.

It must be performed with the highest gain of each type of antenna proposed for use with the EUT. Use the following spectrum analyzer settings:

The EUT was placed on a turn table which is 0.8m above ground plane. Maximum procedure was performed on the highest emissions to ensure EUT compliance.

(2) 300 30 30 3 3 3 3 Access to the World Follow the guidelines in ANSI C63.10-2013 with respect to maximizing the emission by rotating the EUT, measuring the emission while the EUT is situated in three orthogonal planes (if appropriate), adjusting the measurement antenna height and polarization, etc. A pre-amp and a high pass filter are required for this test, in order to provide the measuring system with sufficient sensitivity. Allow the trace to stabilize. The peak reading of the emission, after being corrected by the antenna factor, cable loss, pre-amp gain, etc., is the peak field strength, which must comply with the limit specified in Section 15.35(b). Submit this data. Now set the VBW to 10 Hz, while maintaining all of the other instrument settings. This peak level, once corrected, must comply with the limit specified in Section 15.209. If the dwell time per channel of the hopping signal is less than 100 ms, then the reading obtained with the 10 Hz VBW may be further adjusted by a duty cycle correction factor, derived from 20log(dwell time/100 ms), in an effort to demonstrate compliance with the 15.209 limit. Submit this data. Repeat above procedures until all frequency measured was complete. 8.5.5 Test Results

The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current devices or to devices operated under the provisions of 15.211, 15.213, 15.217, 15.219, or 15.221. Further, this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with 15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that the proper antenna is employed so that the limits in this part are not exceeded. For intentional device, according to FCC 47 CFR Section 15.203, an intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. And according to FCC 47 CFR Section 15.247 (b), if transmitting antennas of directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. 8.6.2 Result The EUTS antenna is Metal antenna.
