Circuit operation explanation ---- BRAIN rf block diagram ---- a1 a2 a3 a4 (Tx data)Modulation Local RF buffer RF amplify a5 oscillation (434.79 MHz) Antenna CPU (PIC16C74B)) b3 b6 RX /TX 2ST oscilationswitching (20.945MHz) b1 b2 b4 b5 RX Fsk FM data 2ST mixer 1ST mixer RF amplif y detection <Picture 1> Input s/w(door pin s/w, hood pin s/w, trunk pin s/w) - A basic carrier frequency consists of a1, a2, a3 (on picture 1). - Receiver : super heterodyne recever - Modulation type : FM FSK(frequncy shift keying) - Brain transmitting frequncy : 434.79MHz - Brain receive local oscillation frequncy : 413.39MHz 1. Brain controller 1.1 Transmission Transmission is executed when input s/w is sensed or received from the remote. Modulation signal is occurred at CPU(location u2) pin no 35. Modulation is formed at a1 (D2), a2 (Q3). a3 (Q4) creates frequency 434.79MHz. The frequency of 434.79MHZ is amplified through the components of a4(Q5,Q6) and b6(rx/tx switching) and transferred to antenna. 1.2 Receiver A carrier frequency (413.39MHz) amplifies at b5 (Q7, Q8) pass through a5 (antenna b5 (Q7,Q8) receives signals of a3 (Q4), b4(Q9) and makes 1st IF (21.4MHz) to send b2 (IC1) mixes with 2nd local oscillation frequency (20.945MHz) of b3 (X102) and 455Khz demodulates FM at b1 (X103) and quadrature detects Sends Fsk out to CPU(location U2) pin no 36.

This product is composed of Brain and Remote. The purpose of signal transmitted from Brain is informing the status of vehicle to user by Remote. After confirmed the status of the vehicle through LCD display and sound of the Remote, the user can do appropriate actions. The Brain is operating to transmit the signal in case of two ways. First, when receiving the signal to operate Door Lock, Door unlock, Panic, Trunk open, Find and Engine start from Remote, the Brain transmits the signal with results of its conduction to Remote as follows. 1) Brain operates Door motor, which is built in the door, to lock the door when receiving the order of Door lock. 2) After operating, Brain transmits the pulse code signal, which is frequency modulated from the pre-arranged pulse, to remote. Second, When the condition of vehicle is changed, the Brain transmits the signal with status of vehicle to Remote as follows. 1) Door open CPU of Brain senses the change of the voltage, 12V to 0V on Door pin switch if Door opens 2) Trunk open CPU of Brain senses the change of the voltage, 12V to 0V on Trunk pin switch if Trunk opens 3) Hoop open CPU of Brain senses the change of the voltage, 12V to 0V on Hood pin switch if Hood opens 4) Shock sensor CPU of Brain senses the change of the voltage, 5V to 0V if the impact to vehicle is transmitted to Shock sensor. 5) Engine start CPU of Brain senses the change of the voltage, 0V to 12V if engine is started. The above described cases, No. 1) ~ 5) are called as the events For example, If Door open while vehicle is in arm, the Brain transmits the signal, which is frequency modulated from its pre-arranged pulse, to Remote after CPU of Brain senses the change of the voltage on Door pin switch, 12V to 0V. As a result, the transmission signal is not data but the pulse code signal, which is frequency modulated from the pre-arranged pulse. Actually, the Remote is controlled to turn on LCD and sound when the Brain transmits the signal. The information of code pulse and transmission time are following; z 1 Bit = 430us z 1 Frame = 120Bit(120x430us = 51.6ms) z Total transmission time for one transmission = 4074.8 ms 51.6ms Total transmission Time at event(118.2ms x 35 - 62.2 = 4074.8ms) 4074.8ms 118.2ms

Test Procedure 1.1 Preliminary Testing for Reference Preliminary testing was performed in a KTL absorber-lined room to determine the emission characteristics of the EUT. The EUT was placed on the wooden table which has dimensions of 0.8 meters in height, 1 meter in length and 1.5 meters in width. Receiving antenna (Biconical antenna : 30 to 300 MHz, Log-periodic antenna : 200 to 1000 MHz or Horn Antenna : 1 to 18 GHz) was placed at the distance of 1 meter from the EUT. An attempt was made to maximize the emission level with the various configurations of the EUT. Emission levels from the EUT with various configurations were examined on a spectrum analyzer connected with a RF amplifier and graphed by a plotter. 1.2 Fin…
