Operational Principle 1. CPU,HS6228 have an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. Opration frequency is 3.5 MHz with internal RC oscillator., This chip is responsible to control RF-Baseband Transceiver(HS6228). 2. Matrix,8*18 matrix with eight input line and eighteen output line. 3. 2.4 GHz ISM Band Transceiver/Framer,HS6228 which is a low-cost,fully inegrated CMOS radio frequency(RF) transceiver block,combined with a 64-byte buffered framer block.It contains transmit,receive,VCO and PLL functions,including an on-chip channel filter and resonator. It needs an external 16MHz crystal for reference frequency; 4. ANTENNA, The antenna is typically fed from the end of the monopole section by a plated through-hole via which is in turn connected to the RF output on the 2.4GHz band. 5.

Report No.: RA230529-29950E-RF-00 Version24: 2023-01-30 Page 11 of 37 FCC-FHSS FCC§15.247 (i)&§1.1307 (b) &§2.1093 – RF EXPOSURE Applicable Standard According to FCC §2.1093 and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D01 General RF Exposure Guidance 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 1. f(GHz) is the RF channel transmit frequency in GHz. 2. Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. Measurement Result Frequency (MHz) Maximum Tune-up power Calculated Distance (mm) Calculated Value Threshold (1-g SAR) SAR Test Exclusion (dBm) (mW) 2402-2480 1.0 1.26 5 0.4 3.0 Yes Note: the maximum tune up power was declared by the applicant. Result: Compliant.
