Label: Model:Light-005 FCCID:2BWWC‐LIGHT005 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. 50mm 27mm

FCC ID:2BWWC-LIGHT005 RF Exposure Evaluation According to KDB 447498 D01 General RF Exposure Guidance v06 and part 2.1091，Unless specifically required by the published RF exposure KDB procedures, standalone 1-g heador body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. Limits The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) Limits for Maximum Permissible Exposure (MPE) Frequency range (MHz) Electric field strength (V/m) Magnetic field strength (A/m) Power density (mW/cm 2 ) Averaging time (minutes) (A) Limits for Occupational/Controlled Exposures 0.3–3.06141.63*(100)6 3.0–301842/f4.89/f*(900/f 2 )6 30–30061.40.1631.06 300–1500f/3006 1500–100,00056 (B) Limits for General Population/Uncontrolled Exposure 0.3–1.346141.63*(100)30 1.34–30824/f2.19/f*(180/f 2 )30 30–30027.50.0730.230 300–1500f/150030 1500–100,0001.030 f = frequency in MHz Friis transmission formula:Pd = (Pout*G)/(4*pi*r 2 ) Where Pd= power density in mW/cm 2 ,Pout= output power to antenna in mW; G= gain of antenna in linear scale,Pi=3.1416; R= distance between observation point and center of the radiator in cm Pd id the limit of MPE, 1 mW/cm 2 . If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where theMPE limit is reached. Test Procedure Software provided by client enabled the EUT to transmit and receive data atlowest, middle and highest channel individually. Test Result of RF Exposure Evaluation So a SAR test is not required Operating Mode Frequency Measured Power Tune up tolerance Max.
