Abstract

본 발명은 카오디오의 도난방지 장치에 관한 것으로, 시동이 꺼졌을때 경보등을 점등시키는 도난예방 표시부를 구비하고 시험모드일 때에는 설정키에 의하여 설정시간 동안만 정상동작하고, 시험모드가 아닐때에는 비밀코드을 입력시키되 2회까지만 비밀코드입력 기회를 부여토록 하는 장치로써, 도난방지 기능을 가지며 시험모드 때는 설정시간 동안 시험할수 있고 사용시에는 3회 미만까지 비밀코드 입력기회를 제한하여 신뢰도를 향상시킨 장치이다.The present invention relates to an anti-theft device of a car audio, comprising an anti-theft display unit for turning on an alarm lamp when the start-up is turned off, and in the test mode, operates normally only for a set time by the setting key, and when the test mode is not secret, It is a device that allows you to enter a code but gives you a chance to enter a secret code only up to two times. It has an anti-theft function and can be tested for a set time in test mode, and improves reliability by limiting the secret code input opportunity to less than three times when used. .
