RF EXPOSURE EVALUATION METHOD FCC ID: 2BXJW-T2 Applicable standard： In accordance with FCC 47 CFR part 2 (2.1093) this device has been defined as a portable device which 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. Portable devices must be evaluated using the specified in FCC 47 CFR part 2 (2.1093). and had been tested in accordance with the measurement methods and procedures specified in IEEE 1528-2003. Per FCC KDB 447498 D01 v06, the 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances s 50 mm are determined by: SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. 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 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.

Record the max value. 11.4 Test Result Condition Mode Frequency (MHz) Conducted Power (dBm) Limit (dBm) Verdict NVNT 1-DH5 2402 2.80 30 Pass NVNT 1-DH5 2441 3.00 30 Pass NVNT 1-DH5 2480 2.33 30 Pass NVNT 2-DH5 2402 3.81 21 Pass NVNT 2-DH5 2441 3.94 21 Pass NVNT 2-DH5 2480 3.33 21 Pass NVNT 3-DH5 2402 3.82 21 Pass NVNT 3-DH5 2441 3.94 21 Pass NVNT 3-DH5 2480 3.32 21 Pass Report No.:BCTC2608630719-1E No.：BCTC/KJ-RF-ICT-001 Page 60 of 88 Edition：B.1 Test Graphs Power NVLT 1-DH5 2402MHz Power NVLT 1-DH5 2441MHz Report No.:BCTC2608630719-1E No.：BCTC/KJ-RF-ICT-001 Page 61 of 88 Edition：B.1 Power NVLT 1-DH5 2480MHz Power NVLT 2-DH5 2402MHz Report No.:BCTC2608630719-1E No.：BCTC/KJ-RF-ICT-001 Page 62 of 88 Edition：B.1 Power NVLT 2-DH5 2441MHz Power NVLT 2-DH5 2480MHz Report No.:BCTC2608630719-1E No.：BCTC/KJ-RF-ICT-001 Page 63 of 88 Edition：B.1 Power NVLT 3-DH5 2402MHz Power NVLT 3-DH5 2441MHz Report No.:BCTC2608630719-1E No.：BCTC/KJ-RF-ICT-001 Page 64 of 88 Edition：B.1 Power NVLT 3-DH5 2480MHz Report No.:BCTC2608630719-1E No.：BCTC/KJ-RF-ICT-001 Page 65 of 88 Edition：B.1 12. Hopping Channel Separation 12.1 Block Diagram Of Test Setup 12.2 Limit Frequency hopping systems shall have hopping channel carrier frequencies separated by a minimum of 25 kHz or the 20 dB bandwidth of the hopping channel, whichever is greater. Alternatively, frequency hopping systems operating in the 2400-2483.5 MHz band may have hopping channel carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping channel, whichever is greater, provided the systems operate with an output power no greater than 0.125W. 12.3 Test procedure 1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port to the spectrum. 2. Set the spectrum analyzer: RBW = 30kHz. VBW = 100kHz , Span = 2.0MHz. Sweep = auto; Detector Function = Peak. Trace = Max hold. 3. Allow the trace to stabilize. Use the marker-delta function to determine the separation between the peaks of the adjacent channels. The limit is specified in one of the subparagraphs of this Section Submit this plot. 12.4 Test Result Condition Mode Hopping Freq1 (MHz) Hopping Freq2 (MHz) HFS (MHz) Limit (MHz) Verdict NVNT 1-DH5 2402.044 2403.048 1.004 0.663 Pass NVNT 1-DH5 2442.050 2441.070 0.980 0.637 Pass NVNT 1-DH5 2479.030 2480.046 1.016 0.665 Pass NVNT 2-DH5 2403.050 2402.038 1.012 0.849 Pass NVNT 2-DH5 2442.050 2441.040 1.010 0.851 Pass NVNT 2-DH5 2480.054 2479.054 1.000 0.874 Pass NVNT 3-DH5 2403.186 2402.186 1.000 0.850 Pass NVNT 3-DH5 2442.046 2441.050 0.996 0.874 Pass NVNT 3-DH5 2480.054 2479.050 1.004 0.866 Pass Note: For conducted power less than 0.125 W(21 dBm), the limit can be set using hopping channel carrier frequencies that are separated by 25 kHz or two thirds of the 20 dB bandwidth of the hopping channel, whichever is greater.
