Abstract:
1. An operating method of a remote control device, comprising steps of: a) providing a recognition code in a central control unit of a memory host in a car having burglarproof function to distinguish an emitting device of a particular group from an emitting device of a different group, wherein a memory circuit is ready for storing a reading code in a memory device; b) checking if a receiving recognition code corresponds to said recognition code of said central control unit and actuating responsive thereto a code learning function of said host, an emitting device of the particular group in an effective range of said host thereby placing said host under code learning mode, and thereafter transmitting a new code to a register of said host; c) determining whether said new code is of a master code or a user code form; d) additionally determining whether prior entry has been made in said memory device of any code having the same code form as said new code, and selectively clearing said memory device responsive thereto; and, e) storing said new code in said memory device to replace an old code and achieve code wash function.
