1. 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 ACTION LOCK Lock the door and output the signal to security unit UNLOCK Unlock the door and output the signal to security unit BOOT RELEASE Release the boot PANIC Beep the horn and flush the small light. (it continues 30 seconds) This receiver also controls wired operation. When the key is in the driver’s 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 diver’s side door is mechanically unlocked. It is also available to control the door lock status by using the remote door control switch(both driver’s and passenger’s side). Transmitter f = 313.85MHz - 1 -
2. User’s manual (provisionally) LOCK When you push the LOCK button, all the doors will lock. And output the signal to security unit. 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 once, all the door s will unlock. And output the signal to security unit. You cannot unlock any of the doors with the remote transmitter if the key is in the ignition switch. BOOT RELEASE To open the boot, push the BOOT RELEASE button for approximately 0.5 second. The boot will not open if the key is in the ignition switch. PANIC MODE Panic mode allows you to remotely sound your vehicle’s horn to attract attention. To activate this mode, press and hold the PANC button for about one second. Your vehicle’s 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 to ON. Panic mode will not activate if the ignition switch is in ON. - 2 - CAUTION: Changes or modifications not expressly approved by the manufacturer responsible forcompliance could void the user's authority to operate the equipment

5. Features 5.1 Integrated controller The controller works both wireless and wired operation. You can use it remotely as the receiver of the keyless entry system. You can operate the door lock remotery using the remote transmitter. It is also avialable to release the boot. When you turn the door lock switch, the controller works as the door lock controller. The controller monitors the switch related to the door lock. In case of the status of the switch changed, the controller will detect and output the signal to the door lock actuator. / SIGNAL FORM / Synchronous Header Identification code code code security code function code (324bit) (4bit) (56bit) 5.2 Battery saving The receiver works intermittently to reduce the battery consumption. The microcomupter mounted on the receiver controlls the power supply for the RF circuit. In case of the microcomputer detects the wake-up signal during the power supplied, the microcomputer continue supplying the power until the data frame will be received. - 5 -
