1.    Constitution of the Radio Frequency Keyless Entry     System for vehicle   The radio frequency keyless entry is  a  system  that  it  controls  locking and unlocking  the  door  and  the            trunk and the panic by wireless remote controller. This system consists of three 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 and crc 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 receiving 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            UNLOCK                                                    unlock the door           TRUNK                                                     open the trunk                   PANIC                                                  alarm the horn                                                                         Transmitter                                                               f = 313.85MHz                                                                                                                                  - 1 -
2. User's manual (provisionally)    REMOTE TRANSMITTER         OKA- 950T            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 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.        TRUNK     When you push continuously the TRUNK button during 1s, TRUNK will open.       PANIC     When you push the PANIC button, horn will alarm.                                                              - 2 -

 5.Features    5.1 Door lock control      The LOCK relay in the receiver drives  the door lock actulators to "LOCK"-side when LOCK button of      transmitter was pressed. The UNLOCK relay in the receiver drives         5.2    Battery saving      To prevent the battery exhaustion , the micro-computer of the transmitter is usually inactive. When the button      will be pressed, the micro-computer wakes up immediately and judges which button is pressing. Then the      micro-computer constructs the transmission frame and radiates it from the antenna .After transmitting, the      micro-computer switches stand-by mode by itself.          6.
