When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion According to KDB447498D01 General RF Exposure Guidance v06 Standalone SAR test exclusion considerations Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Exclusion Threshold condition, listed below, is satisfied. 90187-23-72-23-PP002 Page 2 of 2 Address: No.11, WuSong Road, Tel: 86-769-22607797 DongchengDistrict,Dongguan, Fax: 86-769-22607907 GuangdongProvince,China523117 http://www.cpcteam.com Calculated Result and Limit Operation Mode: GFSK, 8DPSK Channel Maximum Peak Conducted Output Power (dBm) Tune up tolerance (dBm) Maximum tune-up Power Calculated value Exclusion threshold (dBm) (mW) GFSK -Lowest (2402MHz) 7.60 7±1 8 6.30 1.95 3.0 GFSK -Middle (2440MHz) 7.17 7±1 8 6.30 1.97 GFSK -Highest (2480MHz) 7.09 7±1 8 6.30 1.98 Conclusion: the calculated value ≤3.0, SAR is exempted.
