To shut me down if you are finished and it is the end of the day: Close the Netscape window by clicking in the upper left corner. Close the Program Manager Window by clicking in the upper left corner. Click on "Yes" to close the Windows Session. At the F:LOGIN prompt, shut off the Master power button--the red one at the right hand side of the power strip under the terminal. You do not need to shut anything off on the drive unit itself.
