Test Model No.: NR4‐141601

FCC ID：2AHZK101200 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Label Size:6cm*3cm

Test Model No.: NR4‐141601

FCC ID: 2AHZK101200 According to 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(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, where --f(GHz) is the RF channel transmit frequency in GHz --Power and distance are rounded to the nearest mW and mm before calculation --The result is rounded to one decimal place for comparison eirp = pt x gt = (EXd) 2 /30 where: pt = transmitter output power in watts, gt = numeric gain of the transmitting antenna (unitless), E = electric field strength in V/m, --- 10 ((dBuV/m)/20) /10 6 d = measurement distance in meters (m) ---3m So pt = (EXd) 2 /30 x gt Field strength = 90.70dBuV/m @3m Ant gain =2dBi, so Ant numeric gain= 1.58 So pt={ [10 90.70/20) /10 6 x 3] 2 /30x1.58}x1000 mW =0.222mW So (0.222mW /5mm)x √2.442=0.069<3 Then SAR evaluation is not required
