Report No: 128S067R-RF-US-P20V01 1. RF Exposure Evaluation 1.1. Limits According to FCC 1.1310: 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) Electric Magnetic Power Average Frequency Field Field Density Time Range (MHz) Strength Strength (mW/cm2) (Minutes) (V/m) (A/m) (A) Limits for Occupational/ Control Exposures 300-1500 -- -- F/300 6 1500-100,000 -- -- 5 6 (B) Limits for General Population/ Uncontrolled Exposures 300-1500 -- -- F/1500 6 1500-100,000 -- -- 1 30 F= Frequency in MHz Friis Formula Friis transmission formula: Pd = (Pout*G)/(4*pi*r2) Where Pd = power density in mW/cm2 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/cm2 . 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 the MPE limit is reached. Page: 4 of 5

Report No: 128S067R-RF-US-P20V01 1.2. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. The temperature and related humidity: 18℃and 78％ RH. 1.3. Test Result of RF Exposure Evaluation Product : Surface Radio Test Item : RF Exposure Evaluation Test Site : AC-6 Antenna Gain: Antenna Gain: The maximum Gain measured in fully anechoic chamber is 2dBi in logarithm scale. Output Power into Antenna & RF Exposure Evaluation Distance: Maximum Output Power to Power Density at R = 20 cm Frequency Band (MHz) Antenna (mW) (mW/cm2) 2418~2460MHz 73.6207 0.023213 Note: The power density Pd (4th column) at a distance of 20 cm calculated from the Friis transmission formula is far below the limit of 1 mW/cm2.
