- 1 -1. Constitution of the Radio Frequency Keyless Entry Controller Systemfor vehicleThe radio frequency keyless entry is a system that it controllers 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. TheRECEIVER is fixed inside the vehicle. It works intermittently to prevent the battery exhaustion. When the receiver detects thesynchronous code, it runs continuously to receive the signals completely. After receiving the signal, the receiver decides whichoperation will be performed. The user can select the following operations by pressing the button of the remote transmitter.
- 2 -2. User's manual (provisionally) REMOTE TRANSMITTERYou 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 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 any door is open or the key is in the ignition switch.

- 5 -5.Features 5.1 Door lock controlThe LOCK relay in the receiver drives the door lock actuators to "LOCK"-side when LOCK button of transmitter was pressed.The UNLOCK relay in the receiver drives the door lock actuators to "UNLOCK"-side when UNLOCK button of transmitterwas pressed. These facility doesn't work if the key is inserted the key cylinder or the door is open. 5.2 Battery savingBecause of the power source of the receiver is car Battery, it is very important problem to minimize a power consumption. Thereceiver's CPU works intermittently to prevent the battery exhaustion.6.DerivativesOKA-700R is an integrated controller for a car body control, includes the keyless entry receiver. The integrated controller consists ofthe multiple control functions as follows, centralized door lock, turn-signal lamp, room-lamp, intermitted wiper, power window timer,ignition key illumination, auto light, warning buzzer and so on.INFORMATION TO THE USERThis equipment has been tested and found to comply with the limits for a Class B digital device, pursuant topart 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmfulinterference in a residential installation. This equipment generates, uses and can radiate radio frequencyenergy and, if not installed and used in accordance with the instructions, may cause harmful interference toradio communications. However, there is no guarantee that interference will not occur in a particularinstallation. If this equipment does cause harmful interference to radio or television reception, which can bedetermined by turning the equipment off and on, the user is encouraged to try to correct the interference byone more of the following measures:Reorient or relocate the receiving antenna.Increase the separation between the equipment and receiver.Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.Consult the dealer or an experienced radio/TV technician for help.WA RN INGChanges or modifications not expressly approved by the manufacturer could void the user’s authority to operate theequipment.
