DEVICE AND METHOD FOR SENSING BURGLARPROOF CODE OF CAR AUDIO

摘要

PURPOSE: A device and method for sensing a code are provided to automatically input the burglarproof code when power turns on after intercepted by repair, change of a battery or additional troubles. CONSTITUTION: When a user turns on a car audio using a power switching unit(100), a car audio microcomputer(200) is input the signal from the power switching unit and outputs a control signal. Then an EEPROM(300) is input the control signal and outputs the stored burglarproof code and the microcomputer is input the burglarproof code and outputs a burglarproof code data to an electric device controlling unit(500) for storing the burglarproof code. The control signal of the microcomputer is input to a display unit(400) for displaying the input mode of the burglarproof code.
