Constitution of the Radio Frequency Keyless Entry System with Door Lock Controller for vehicle The radio frequency keyless entry is a system that it controlls locking and unlocking the door by wireless remote controller. This system consists of two components. The TRANSMITTER is a device that transmits the signal when the button is pressed. The transmission signal consists of several synchronous codes, unique identification code, security code and function code. The RECEIVER is fixed inside the vehicle. It works intermittently to prevent the battery exhaustion. When the receiver detects the synchronous code, it runs continuously to receive the signals completely. After receiveing the signal, the receiver decides which operation will be performed. The user can select the following operations by pressing the button of the remote transmitter. OPERATION LOCK UNLOCK PANIC ACTION Lock the door Unlock the door Open the window Beep the horn and flush the small light. (it continues 30 seconds) This receiver also controls wired operation. When the key is in the drivers side key cylinder, all doors will Unlock if the key is turned to UNLOCK and hold more than one second. In case of the operation time is shorter, the only divers side door is mechanically unlocked. It is also available to control the door lock status by using the remote door control switch(both drivers and passengers side). Transmitter f = 313.85MHz

2. Users manual (provisionally) REMOTE TRANSMITTER You can lock and unlock your vehicle with the remote transmitter. LOCK When you push the LOCK button, all the doors will lock. You cannot lock any of the doors with the remote transmitter if any door is open or the key is in the ignition switch. UNLOCK When you push the UNLOCK button , all the doors will unlock. You cannot unlock any of the doors with the remote transmitter if the key is in the ignition switch. When you push the UNLOCK button more than about 1.0 second , the window will open. PANIC MODE Panic mode allows you to remotely sound your vehicles horn to attract attention. To activate this mode , press and hold the PANIC button for about one seconds. Your vehicles horn will beep for about 30 seconds. To cancel Panic mode before 30 seconds , press any button on the remote transmitter. You can also turn the ignition switch is in ON
