Report Number: 1908FS16 Rev.00 1. Reference Testing Standards Standard Description Version American National Standard safety levels with respect to human ANSI/IEEE C95.1 exposure to radio frequency electromagnetic fields, 300 kHz to 100 1992 GHz, New York. IEEE Recommended Practice for Determining the Peak IEEE 1528 Spatial-Average Specific Absorption Rate (SAR) in the Human Head 2013 From Wireless Communications Devices: Measurement Techniques. FCC 47 CFR Part 2.1093 Radiofrequency radiation exposure evaluation: portable devices. --- SAR measurement 100 MHz to 6 GHz - describes SAR FCC KDB 865664 D01 measurement procedures for devices operating between 100 MHz to v01r04 6 GHz RF Exposure Reporting - provides general reporting requirements as FCC KDB 865664 D02 well as certain specific information required to support MPE and SAR v01r02 compliance.

Report Number: 1908FS16 Rev.00 2. Description of Equipment under Test (EUT) LEXON Applicant 91 avenue Jean-Baptiste Clément - 92100 Boulogne - FRANCE LEXON Manufacturer 91 avenue Jean-Baptiste Clément - 92100 Boulogne - FRANCE Product Type TYKHO 3 Trade Name LEXON Model Number LA119 FCC ID 2ARD3-LA-119 Frequency Range Operate Band (MHz) Frequency Range Bluetooth BR/EDR 2402 - 2480 Bluetooth LE 2402 - 2480 Max. Gain Type Antenna information (dBi) Inverted F Antenna -0.58 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. Page 5 of 8

Report Number: 1908FS16 Rev.00 3. 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: ≤50 mm: [(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 >50 mm and <200 mm: 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 Page 6 of 8

Report Number: 1908FS16 Rev.00 3.2 Evaluation Results The evaluation of SAR test reduction according to KDB447498 SAR test is not required when the results showed “EXEMPT”. SAR test reduction Distance of Ant. Frequency Power Calculated threshold value Ant. Used Band To User (mm) (GHz) (dBm) (mW) Front Back Front Back 0.6 0.6 DSS Bluetooth 2.441 3 1.995 5 5 EXEMPT EXEMPT Exclusion Considerations: SAR is not required Note: 1. Calculated Value include string "mW",that is meam 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 inculde 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. ---END--- Page 8 of 8
