Report No.: E2/2017/90035 1 MAXIMUM PERMISSIBLE EXPOSURE (MPE) 1.1 Standard Applicable According to §1.1307(b)(1), systems operating under the provisions of this section shall be op- erated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. This is a Mobile device, the MPE is required. According to §1.1310 and §2.1091 RF exposure is calculated. Limits for Maximum Permissive Exposure (MPE) Frequency Range Electric Field Magnetic Field Power Density Averaging Time (MHz) Strength (V/m) Strength (A/m) (mW/cm2) (minute) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 1.34-30 824/f 2.19/f *(180/f2 ) 30 30-300 27.5 0.073 0.2 30 300-1500 / / F/1500 30 1500-15000 / / 1.0 30 F = frequency in MHz * = Plane-wave equipment power density Unless otherwise stated the results shown in this test report refer only to the sample(s) tested and such sample(s) are retained for 90 days only. 除非另有說明，此報告結果僅對測試之樣品負責，同時此樣品僅保留90天。本報告未經本公司書面許可，不可部份複製。 This document is issued by the Company subject to its General Conditions of Service printed overleaf, available on request or accessible at www.sgs.com/terms_and_conditions.htm and, for elec- tronic format documents, subject to Terms and Conditions for Electronic Documents at www.sgs.com/terms_e-document.htm.

Output include tune up tolerance Power is average power MPE Prediction (BLE 2402~2480) Prediction of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 S=PG/4πR2 Where: S = Power density P = Power input to antenna G = Power gain of the antenna in the direction of interest relative to an isotropic radiator R = Distance to the center of radiation of the antenna Max. output power including tune-up tolerancel: 0.97 (dBm) Max. output power including tune-up tolerancel: 1.250259 (mW) Duty cycle: 65.38 (%) Maximum Pav : 0.8174194 (mW) Peak Antenna gain (Maximum): 4.1 (dBi) Peak Antenna gain (linear): 2.5703958 (numeric) Prediction distance: 20 (cm) Prediction frequency: 2442 (MHz) MPE limit for uncontrolled exposure at prediction 1 frequency: (mW/cm2) Power density at predication frequency at 20 (cm) 0.000 distance (mW/cm2) Measurement Result The predicted power density level at 20 cm is 0 mW/cm2. This is below the uncontrolled exposure limit of 1 mW/cm2 at 2442MHz.
