LCIE SUD EST Laboratoire de Moirans Z.I. Centr’Alp 170, Rue de Chatagnon 38430 MOIRANS – FRANCE RF Exposure Considerations for FCC ID: XKB-AXIPRTBT Per FCC KDB 447498 D01 General RF Exposure Guidance v06 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions. The minimum test separation distance defined in 4.1 f) is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander. Minimum test separation distance: 5 mm Step a) For 100 MHz to 6 GHz and test separation distances ≤ 50 mm The 1-g and 10-g SAR test exclusion thresholds are determined by the following: (max π‘π‘œπ‘€π‘’π‘Ÿ π‘œπ‘“ π‘β„Žπ‘Žπ‘›π‘›π‘’π‘™ (π‘šπ‘Š)) × √𝑓(𝐺𝐻𝑧) ≤ 3.0 π‘“π‘œπ‘Ÿ 1 − 𝑔 𝑆𝐴𝑅 π‘œπ‘Ÿ ≤ 7.5 π‘“π‘œπ‘Ÿ 10 − 𝑔 𝑒π‘₯π‘‘π‘Ÿπ‘’π‘šπ‘–π‘‘π‘¦ 𝑆𝐴𝑅 (min 𝑑𝑒𝑠𝑑 π‘ π‘’π‘π‘Žπ‘Ÿπ‘Žπ‘‘π‘–π‘œπ‘› π‘‘π‘–π‘ π‘‘π‘Žπ‘›π‘π‘’ (π‘šπ‘š)) Where:  f(GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation31  The result is rounded to one decimal place for comparison  The values 3.0 and 7.5 are referred to as numeric thresholds in step b) below 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. Maximum source- based time averaged conducted output Minimum Limit for Frequency power or EIRP (worst separation Result of Limit for 10-g Channel Verdict (GHz) case) distance Eq. 1 1-g SAR extremity including tune-up (mm) SAR tolerance (dBm) (mW) Min 2.402 -2.6 0.55 5 0.17 3 7.5 Exempt from SAR Mid 2.440 -2.8 0.52 5 0.16 3 7.5 Exempt from SAR Max 2.480 -2.7 0.54 5 0.17 3 7.5 Exempt from SAR Conclusion: Therefore our device complies with FCC’s RF radiation exposure limits for general population without SAR evaluation.
