- 12.4 sec before lockloss, K1:VIS-ETMY_MN_OPLEV_TILT_SUM_OUT_DQ shows sudden decrease (1060 --> 1050)
- 12.0 sec before lockloss, K1:VIS-ETMY_TM_WIT_P_DQ shows a big gritch with duration of ~1sec. Similar glitch is found in VIS-ETMY_MN but not in ETMX
- 12.0 sec before lockloss, K1:OMC-TRANS_DC_{A_IN1, B_IN1, SUM_OUT}_DQ shows a big glitch.
- 10.0 sec before lockloss, K1:OMC-TRANS_DC_{A_IN1, B_IN1, SUM_OUT}_DQ shows a smaller glitch with the duration of ~2sec.
- 5.0 sec before lockloss, K1:VIS-ITMX_TM_WIT_{P,Y}_DQ show the decrease.
- 5.0 sec before lockloss, K1:ASC-DSOFT_P_{IN1, OUT}_DQ show the increase (-200 --> 1000).
- 3.0 sec before lockloss, K1:LSC-TR_{IRX, GRX}_NORM_OUT_DQ starts decreasing.
