RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Motorcycle 4-Way Conference Intercom Model Name T30-S FCC ID 2AQN2-T30-S 2. EVALUATION METHOD According to 447498 D01 General RF Exposure Guidance v05 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 3. CALCULATION P t =8.489dBm=7.06mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(7.06mW /5mm) .[√2.402GHz)]=2.19<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.

So the Amplitude of test plots is equal to Reading level plus the Factor in dB. Use the A dB(μV) to represent the Amplitude. Use the F dB(μV/m) to represent the Field Strength. So A=F. All test modes had been pre-tested. The GFSK modulation is the worst case and recorded in the report. Report No.: AGC00793200401FE03 Page 38 of 55 11. NUMBER OF HOPPING FREQUENCY 11.1. MEASUREMENT PROCEDURE The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings: 1. Span: The frequency band of operation. Depending on the number of channels the device supports, it may be necessary to divide the frequency range of operation across multiple spans, to allow the individual channels to be clearly seen. 2. RBW: To identify clearly the individual channels, set the RBW to less than 30% of the channel spacing or the 20 dB bandwidth, whichever is smaller. 3. VBW ≥ RBW. Sweep: Auto. Detector function: Peak. Trace: Max hold. 4. Allow the trace to stabilize. 11.2. TEST SETUP (BLOCK DIAGRAM OF CONFIGURATION) Same as described in section 8.2 11.3.
