FCC ID: LDKDPC3939DECT Sheet 29 of 89 Sheets ETC Report No.: 13-03-MAS-074 6.11 Safety exposure levels 6.11.1 Standard Applicable: FCC 15.319(i) UPCS devices are subject to the radio frequency radiation exposure requirements specified in FCC parts 1.1307 (b), 2.1091 and 2.1093, as appropriate. All equipment shall be considered to operate in a “general population / uncontrolled environment. For portable devices tests according to IEEE 1528 are requested, if applicable. 6.11.2 Measurement procedure Consideration of radio frequency radiation exposure for EUT is done as SAR test according IEEE1528 (for PP) MPE calculation as below (for FP, Repeater) SAR test results: not applicable MPE calculation: The EUT is considered as a mobile device according to OET Bulletin 65, Edition -97-01. Therefore distance to human body of min. 20 cm is determined. The limit of Power density for General Population / Umcontrolled Exposure is 1.0 mW/cm². Formula: S = EIRP / 4πR² Calculation: EIRP Radiated Power (dBm) 23.39 EIRP Radiated Power (mW) 218.3 R Distance (cm) 20 S Power Density (mW/cm²) 0.0434 Electronics Testing Center, Taiwan No.8, Lane 29, Wenming RD., LeShan Tsuen, GuiShan Shiang, Taoyuan County 33383, Taiwan, R.O.C. Rev. No 1.0

FCC ID: LDKDPC3939DECT Sheet 30 of 89 Sheets ETC Report No.: 13-03-MAS-074 Simultaneous Evaluation: WLAN 2.4GHz, 5GHz and DECT radio can transmit simultaneously. The formula of calculated MPE is: CPD1/LPD1+CPD2/LPD2+…etc. ＜ 1 CPD=Calculated Power Density LPD=Limit of Power Density Radio Technology Worse CPD (mW/cm2) WiFi 2.4 GHz 0.4246 WiFi 5 GHz 0.2071 DECT 0.0434 The MPE evaluation is 0.4246/1+0.2071/1+0.0434/1=0.6751＜1, which confirm the device comply the MPE limit. 6.11.3 Results：Complies Electronics Testing Center, Taiwan No.8, Lane 29, Wenming RD., LeShan Tsuen, GuiShan Shiang, Taoyuan County 33383, Taiwan, R.O.C. Rev. No 1.0
