FCC ID: BP9-MS300ASP2I MPE Calculation : Bluetooth Maximum power Frequency range Max Target Power ANT Gain Maximum EIRP Maximum EIRP Requriment RF function or Mode density (MHz) (dBm) (dBi) (dBm) (mW) (mW/cm2) (mW/cm2) Bluetooth(BDR) 2402.00 ~ 2480.00 1.50 3.25 4.75 2.986 0.0006 1.000 Bluetooth(EDR) 2402.00 ~ 2480.00 -3.50 3.25 -0.25 0.945 0.0002 1.000 ~ ~ ~ ~ ~ ~ Note: Please refer to the operation description for Max tune-up power. The EUT will only be used with a separation of 20 centimeters or greater between the antenna and the body of the user. The MPE sample calculation for this exposure is shown below. ▪S= EIRP / ( 4 R2 π ) - Note = 2.986 / ( 4 X 202 X π ) S= Maximum power density(mW/cm2) = 0.0006 mW/cm2 EIRP= Equivalent Isotropic Radiated Power(mW) R= Distance to the center of the radiation of the antenna(20cm) ▪ Limits for Maximum Permissible Exposure (MPE) Electric Field Magnetic field Frequency range Power Density Averageing time strength strength 2 (MHz) (mW/cm ) (minutes) (V/m) (A/m) 0.3 ~ 1.34 614 1.63 *100 30 2 1.34 ~ 30 824/f 2.19 / f *180 / f 30 30 ~ 300 27.5 0.073 0.2 30 300 ~ 1,500 f / 1500 30 1,500 ~ 100,000 1.0 30 Conclusion : The exposure condition of this device is compliant with FCC
