  3. Transmission range: 30 m or more outside the vehicle
  4. Transmitter Registration Procedure
    1. In registration mode, up to a maximum of 4 EA can be registered.
    2. When re-registering, data is registered anew after deleting the previous TX DATA.
      No. Stored code Code to change Changed code
      1 A C C (A deleted)
      2 A, B, C, D E E (A, B, C, D deleted)
      3 A, B C, D, E C, D, E
      4 A, B C, C, D C
    3. For registration procedures using the Hi-scan tool, refer to "TRANSMITTER CODE REGISTRATION".
  5. Transmitter Signal and Receiver Specifications
    1. Transmission signal
      A. Transmit the corresponding transmission data (transmission frame) twice by pressing TX SW.
      B. If the TX LOCK switch and the UNLOCK switch are pressed simultaneously, only the LOCK signal is output.
