BSL Testing Co.,LTD. Report No.: BSL10544802RF 5.3 Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and the Cable Factor, and subtracting the Amplifier Gain from the Amplitude reading. The basic equation is as follows: Corr. Ampl. = Indicated Reading +Ant.Loss +Cab. Loss – Ampl.Gain The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of -6dB  V means the emission is 6dB  V below the maximum limit. The equation for margin calculation is as follows: Margin = Corr. Ampl. – FCC Part 15C Limit 5.4 Environmental Conditions Temperature: 21 C Relative Humidity: 50 ATM Pressure: 1011 mbar 5.5 Summary of Test Results/Plots According to the data below, the FCC Part 15.205, 15.209 and 15.231 standards, and had the worst margin of: -6.53 dB at 1735.68 MHz in the Horizontal polarization, AV Detector, 9 kHz to 5 GHz, 1 Meters Note: this EUT was tested in 3 orthogonal positions and the worst case position data was reported.

During the testing, the switch was released then the EUT automatically deactivated. 8.3 Environmental Conditions Temperature: 20 C Relative Humidity: 52 ATM Pressure: 1011 mbar 8.4 Summary of Test Results Type of Pulse Width of Pulse Quantity of Pulse Transmission Time Total Time (Ton) ms ms ms Pulse 1 (Wide) 1.296 4 5.184 16.464 Pulse 2 (Narrow) 2.256 5 11.28 Test Period (Tp) Total Time (Ton) Duty Cycle Duty Cycle Factor ms ms % dB 31.824 16.464 52 -5.68 Note:Duty Cycle Factor=20log (Duty Cycle) Please refer to the attached test plots Add:BuildingNo.24,ZhihengndustrialPark,GuankouerRoad,Nantou,NanshanDistrict,Shenzhen,Guangdong,ChinaCertifi cateSearch:http://www.bst-lab.com,Tel:400-882-9628, 8009990305, E-mail:christina@bst-lab.com Page 20 of 23
