V1.0 Page 4 of 7 Report No.: CTL1412082952-WM 1. SUMMARY 1.1. EUT configuration The following peripheral devices and interface cables were connected during the measurement: ● - supplied by the manufacturer o - supplied by the lab o Battery Manufacturer: Jingnengte Model: F970 1.2. Equipment Under Test Power supply system utilised Power supply voltage : o 120V / 60 Hz o 115V / 60Hz o 12 V DC o 24 V DC „ Other (specified in blank below) DC 7.4V from battery 1.3. Description of the test mode 1. Test program used to control the EUT for staying in continuous transmitting mode is programmed. Channel low (5750MHz), mid (5790MHz) and high (5830MHz) with highest data rate are chosen for full testing. 2. Test Mode: Test Mode(TM) Description Remark 1 Transmitting 5750MHz 2 Transmitting 5790MHz 3 Transmitting 5830MHz 1.4. NOTE The EUT is a Wireless Video Transmission System,The functions of the EUT listed as below: Test Standards Reference Report FCC Part 15 Subpart C CTL1412082952-WF (Section15.247) Wireless Video Transmission System(5750-5830MHz) FCC Per 47 CFR 2.1091(b) CTL1412082952-WM

V1.0 Page 5 of 7 Report No.: CTL1412082952-WM 2. TEST ENVIRONMENT 2.1. Address of the test laboratory Shenzhen CTL Testing Technology Co., Ltd. Floor 1-A, Baisha Technology Park, No.3011, Shahexi Road, Nanshan District, Shenzhen, China 518055 The sites are constructed in conformance with the requirements of ANSI C6230, ANSI C63.4 (2009) and CISPR Publication 22. 2.2. Environmental conditions During the measurement the environmental conditions were within the listed ranges: Temperature: 15-35 ° C Humidity: 30-60 % Atmospheric pressure: 950-1050mbar 2.3. Statement of the measurement uncertainty The data and results referenced in this document are true and accurate. The reader is cautioned that there may be errors within the calibration limits of the equipment and facilities. The measurement uncertainty was calculated for all measurements listed in this test report acc. to CISPR 16 - 4 „Specification for radio disturbance and immunity measuring apparatus and methods – Part 4: Uncertainty in EMC Measurements“ and is documented in the Shenzhen CTL Testing Technology Co., Ltd. quality system acc. to DIN EN ISO/IEC 17025. Furthermore, component and process variability of devices similar to that tested may result in additional deviation. The manufacturer has the sole responsibility of continued compliance of the device. Hereafter the best measurement capability for CTL laboratory is reported: Test Range Measurement Notes Uncertainty Radiated Emission 30~1000MHz 4.10dB (1) Radiated Emission 1~12.75GHz 4.32dB (1) Conducted Disturbance 0.15~30MHz 3.22dB (1) (1) This uncertainty represents an expanded uncertainty expressed at approximately the 95% confidence level using a coverage factor of k=2.

V1.0 Page 6 of 7 Report No.: CTL1412082952-WM 3. Method of measurement 3.1. Applicable Standard According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. 3.2. Limit Limits for Maximum Permissible Exposure (MPE)/Controlled Exposure Limits for Maximum Permissible Exposure (MPE)/Uncontrolled Exposure F=frequency in MHz *=Plane-wave equivalent power density 3.3. MPE Calculation Method Predication of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna From the peak EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the gain of the used antenna is 2.5 dBi, the RF power density can be obtained.
