1. Make sure the scanner bed is at the home position (all the way up and all the way out)
2. If a coil is on the table, all element should be plugged in
3. Click the “System” tab at the top of the screen
4. Click on “Control”
5. Click the “Meas & Recon” Tab
6. Click “Standby”
7. Click “Yes” to the pop up message if needed
8. The system will take 1-2 minutes to turn off –you will hear a “clunk” when the
equipment shutdowns and the LCD screen in the scanner room will turn off

Temp/YourName/SubjectID folder
14. Note –please remember to periodically delete saved data from your non-dicom folder
and scanner console temp folder –data is not meant to stay in these folders indefinitely as
there is limited space
