1 - GENERAL INFORMATION 1.1 Product Description for Equipment Under Test (EUT) Applicant: SJ Incorporated Address of Applicant: 8th F,202 Dong,Chunui Techno-Park2,202,Chuni-Dong,Wonmi- Gu,Bucheon-Shi,Kyungki-Do,South Korea Manufacturer 1: SJ Technology(Shenzhen)Co.,Ltd Address of manufacturer: F6, 1 Bldg, A Area, Yintianxifa Industrial Area, Xixiang Town, Baoan District Shenzhen, Guangdong Province, China Manufacturer 2: SJ Incorporated Address of Manufacturer: 8th F,202 Dong,Chunui Techno-Park2,202,Chuni-Dong,Wonmi- Gu,Bucheon-Shi,Kyungki-Do,South Korea General Description of E.U.T Items Description EUT Description: Gyro Receiver Graupner/SJ HoTT Model No.: GR-24 PRO+3xG+3A+3M+Vario Trade Name: GRAUPNER/SJ HoTT Supplementary Model: GR-24 PRO+3xG+3A Frequency Band: 2404.056 MHz ~ 2474.025 MHz Number of Channels: 70 Type of Modulation: FHSS Antenna Gain: 1.5dBi Antenna Type: Integral Antenna Antenna description 2T2R Rated Voltage: Input: DC 3.6V~8.4V Adapter description: Model: N/A Input: N/A Output: N/A Remark: * The test data gathered are from the production sample provided by the manufacturer. 1.2 Objective The objective of the following report is used to demonstrate that EUT operated in a manner that ensures the public is not exposed to radio frequency energy levels in excess of the relative provisions of FCC 47CFR Part 1.1307 Report No.: BCT13HR290-1 Page 3 of 5

1.3 General Description of Test Items Description EUT Frequency band FHSS: 2.400GHz ~ 2.483GHz WLAN: 2.400GHz ~ 2.483GHz WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz WLAN: 5.745GHz ~ 5825GHz Others: __________________________ Device category Portable (<20cm separation) Mobile (>20cm separation) Others __________________________ Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm2) Others: __________________________ Antenna diversity Single antenna Multiple antennas: Tx diversity Rx diversity Tx/Rx diversity Max. output power 13.24dBm (0.0211W) Antenna gain (Max) 1.5dBi (Numeric gain:1.41) Evaluation applied MPE Evaluation SAR Evaluation Note: 1. The maximum output power is 13.24dBm (0.0211W) at 2404.0056MHz (with 1.41 numeric antenna gain.) 2. For mobile or fixed location transmitters, no SAR consideration applied. The minimum separation generally be used is at least 20 cm, even if the calculations indicate that the MPE distance would be lesser. 1.4 Human Exposure Assessment Results Report No.: BCT13HR290-1 Page 4 of 5

EUT parameter (data from the separate report) Given Where G: numerical gain of transmitting antenna; TP: Transmitted power in watt; d: distance from the transmitting antenna in meter Max average output power in Watt (TP) 13.24dBm (0.0211W) Antenna gain (G) 1.5 dBi (Numeric gain: 1.41 ) Total Antenna gain (G) 4.51dBi(Numeric gain: 2.82 ) Exposure classification S=1mW/cm2 Minimum distance in meter (d) 20cm (0.2m) (from transmitting structure to the human body) Yields 30 xPxG S= , P=0.0211W, G=2.82, d=0.2 3770d 2 S=0.0118mW/cm2 Or 30xPxG d= , S=1, P=0.0211W, G=2.82 3770S d=0.0218m Conclusion: S=0.0118mW/cm2 is significant lower than the General Population Exposure Power Density Limit 1mW/cm2 or except the distance when human body proximity to the antenna is less than 2.1cm then will reach the General Population Exposure Power Density Limit (For mobile or fixed location transmitters, the maximum power density is 1.0 mW / cm2 even if the calculation indicates that the power density would be larger.)
