  2. Slide the BiCU [A] in the direction of the blue arrow below and remove it.

    There are three kinds of FFC connectors.

    A: Disconnect the FFC while pushing the lock lever.
    B: Disconnect the FFC while lifting up the lock lever.
    C: Disconnect the FFC while pulling it out straight. It does not have a lock mechanism.

  3. Remove the NVRAM from the old BiCU and attach it to the new BiCU.

    • Attaching the used NVRAM to the new BiCU allows users to use old data such as SP settings.
    • SC995 occurs when replacing the BiCU. Execute SP5-811-004 then turn the main power off and on.
    • Install a new NVRAM [A] so that the indentation [B] on the NVRAM corresponds with the mark on the BiCU. Incorrect installation of the NVRAM will damage both the BiCU and NVRAM.
