FCC ID:HH8TXA-3B527 Page 4 of 36 INTRODUCTION The measurement procedure described in American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9kHz to 40GHz (ANSI C63.4-2001) was used in determining radiated and conducted emissions emanating from Dongyang Security Electronics Co., Ltd. FCC ID : HH8TXA-3B527, Keyless Entry System. These measurement tests were conducted at Nemko Korea Co., Ltd. EMC Laboratory . The site address is 300-2, Osan-Ri, Mohyun-Myun, Yongin-City, Kyungki-Do, KOREA The area of Nemko Korea Corporation Ltd. EMC Test Site is located in a mountain area at 80 kilometers (48 miles) southeast and Seoul International Airport (Incheon Airport), 30 kilometers (18miles) south-southeast from central Seoul. It is located in the valley surrounded by mountains in all directions where ambient radio signal conditions are quiet and a favorable area to measure the radio frequency interference on open field test site for the computing and ISM devices manufactures. The detailed description of the measurement facility was found to be in compliance with the requirements of §2.948 according to ANSI C63.4 on June 06, 2001. Fig. 1.

FCC ID:HH8TXA-3B527 Page 5 of 36 TEST CONDITIONS & EUT INFORMATION Operating During Test The EUT was continuously operated at switch on mode. Operational Description When the button of the remote is pressed, the switching transistor (Q2) is turn ON and the power is applied to the Encoder I.C (U1) and RF ASK Mod Oscillator Stage (Q1). The Encoder I.C (U1) is generated to the security code and data (Manchester coding) according to the button switch, and applied to the transistor Q1-base of the ASK MOD oscillator stage. The ASK MOD oscillator stage is consisted of the SAW resonated oscillator (Q1, SAW1, C6, C7, C8, R3, loop antenna), and oscillated at the frequency of 315.00MHz band when the transistor Q1 base is biased, and stoped to oscillate when the transistor is not biased. The ASK modulation is performed by the Encoder data st…
