    1. Make marks on FFU switches that are not turned off in MCE, IFI, PRM, PR3, PR2, BS, SR2, SR3, SRM, OMC with "Pink Tape".
    2. 4 people stand by (MCE, IFI, PRM), (PR3, PR2, BS), (SR2, SR3), (SRM OMC) FFU switchs.
    3. Keep taking sensitivity of FPMI condition by an operator.
    4. Turn off almost FFUs at the same time by 4 people, except for pink one.
    5. Check the difference btw FFU operation and alnost-no operation.
