RF Exposure Evaluation for 2ADMUDOTTI6821 Refer user manual this device is a Bluetooth audio with FM transmitter and charger and this device was designed used in fixed devices the minimum distance between human’s body is 20cm. Based on the 47CFR 2.1093, this device belongs to fixed device. The definition of the category as following: Portable Derives: CFR Title 47 §2.1093(b) (b) For purposes of this section, a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. FCC KDB 447498 D01 General RF Exposure Guidance v05r02 Limit Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or 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, listed below, is satisfied. These test exclusion conditions are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions. The minimum test separation distance is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander. 1) 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  3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. 2) At 100 MHz to 6 GHz and for test separation distances > 50 mm, the SAR test exclusion threshold is determined according to the following, and as illustrated in below table: a. [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50 mm)·( f(MHz)/150)] mW, at 100 MHz to 1500 MHz b. [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50 mm)·10] mW at > 1500 MHz and ≤ 6 GHz RF Exposure Evaluation Result Table: Evolution Mode Power condition Max. power transmitting Evaluation Frequency(MHz) 2450MHz Peak Conducted power (mW) 1.06 RF Exposure evolution result FCC exclusion condition 1.06mW＜96mW Verdict Pass
