• Noise investigation about FFUs in the corner stations
  • Method

    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".
       (Operated FFU / Total FFU) list is,
       

  area name	MCE	IFI	PRM	PR3	PR2	BS	SR2	SR3	SRM	OMC
  Operation/Total	2/16	2/12	2/12	4/16	4/20	4/20	4/20	4/16	4/16	4/16

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.
