Labels are printed in indelible ink on permanent adhesive backing or silk-screened onto the EUT or shall be affixed at a conspicuous location on the EUT. Where the EUT is constructed in two or more sections connected by wires and marketed together, the above statement is required to be affixed only to the main control unit. When the EUT is so small or for such use that it is not practicable to place the statement on it, the above information shall be placed in a prominent location in the instruction manual or pamphlet supplied to the user or, alternatively, shall be placed on the container in which the device is marketed.

FCC ID: 2BFDN-LIV-222 RF Exposure Evaluation According to KDB 447498 D01 General RF Exposure Guidance v06 and part 2.1093，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(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(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 Here, The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction. For BR+EDR Max Conducted Power(dBm) Tune-up Power(dBm) Max Tune-up Power(dBm) Max Power(mW) Frequency(MHz) Min. distance(mm) Calc. thresholds limit -7.28 -8(±1) -7 0.2 2402 5 0.061993 3.0 So a SAR test is not required
