Tidying Up

Tidying Up e.g. before next Operator

End of day “to do” procedures shown in ORANGE
- if you're the last Operator of the day (according to Calpendo).

SUMMARY

• UPSs in place, to remain powered/protecting equipment. REO Isolation Transformer removed.
• EyeLink Host PC to be shut down after use, the 6-way Mains extension bar plug then switched off (to power off Camera).
• EyeLink batteries charged/used as normal. Don't leave switched on/charging overnight. Make sure the AC Adapter in the Stimulus Cabinet is switched off.
• PROPixx projector to remain powered, to be "awakened" or "slept" as necessary. Lens cover can be left off.
• STIM PC to remain powered, leave switched to NEW Stim via KVM at End of Day (a screensaver is set to protect monitor).
• NAtA Response Box Controller to remain powered up.
• All other Tiding Up as per our usual procedures...
  • L2V Converters switched off after use.
  • HPI coils cleaned.
  • Polhemus cabling left tidy, L2V FO cabling/NAtA Response Box FO cabling/EyeLink cabling, left tidy in MSR.
  • Log out of the DACQ Console, switch off the DACQ Console monitor once login screen appears.
  • Fill out a Maintenance Log report for your session (one report for each session, if you have consecutive sessions).
  • Move the gantry to 25, if you're the last Operator of the day/End of Day, or more than ~1hr between daily booked slots (check Calpendo).

Remember to check Calpendo to see if another Operator has booked the next session after yours;
in that case, you may be able to leave some equipment powered up.

FULL PROCEDURE

• Remove, and throw away, disposable response box covers (if used). If not, wipe down NAtA response boxes - with Alcohol wipes (not gel!). Be careful! Don't wipe too hard!
• Throw away disposable electrodes/used Micropore tape.
• If used, Clean EEG cap.
• Clean reusable electrodes.
  • Carefully remove the double-sided sticky disc, and any Micropore tape, and dispose of in the bin.

  • Dry the electrode using a green paper towel, and hang the cable over the handle of the EEG trolley.
• Remove as much Teagderm as possible from each HPI coil - be gentle - DON'T PULL on coil or cable!.

Use a piece of Blenderm tape to pull/pick off ("stipple") the remaining stubborn small bits of Teagderm tape from the coloured heatshrink sections of each HPI coil.

• Wash HPI coils in warm, soapy water - DON'T GET grey end connector wet!
• Dry coils with a green paper towel.
• Soak coils in Isoproply Alcohol (IA) (marked tub) for a few minutes, then wipe with a paper towel and leave to dry on a green paper towel.

  • Resoak again in IA if necessary.
• Leave the HPI lead coiled up on a green paper towel to dry off on the EEG trolley.
• Replace the internal cover on any open pot of Isopropyl Alcohol, then screw on the lid gently but firmly. Leave pot upright on EEG trolley.
  • If end of day, return Isopropyl Alcohol pots to red Flammables cabinet located in Changing Room.
• Throw away used cotton buds/used paper towel/Tegaderm backing paper.

ppx a / ppx s didn't work on one occasion. PROPixx needed a full power off/on to reset.

Projector lens cover to remain off, so the projector state can easily be determined.
