POWER SUPPLY METHOD OF CAR AUDIO SYSTEM

摘要

PURPOSE: A power supply method of car audio system is provided to turn on a car audio system with any function keys equipped in the car audio system. CONSTITUTION: An input of a key operation signal by user's key operation(S200) from any one key among a plurality of keys is detected(S210). A car audio system is turned on with the generation of a control signal(S220). The last operation mode before the power of the car audio system is off is confirmed(S230). The insertion of a cassette tape is confirmed(S240). The cassette tape is regenerated in response to the control signal from a microcomputer(S250). The microcomputer confirms whether a compact disk is inserted in a compact disk regeneration part(S260). The compact disk regeneration part regenerates the compact disk in response to the control signal from the microcomputer(S270). A tuner part outputs radio broadcasts in response to the control signal from the microcomputer(S280).
