User reported overnight that there was no beam and that the beam blanking logic had
become reversed.  Could not reach that user reporting as they did not leave me a number
to call back to...
Upon my morning arrival to the lab at ten AM I found the system had been tampered with:
 -- laser power supply was switched off manually
- Digital Pattern generator manual 'beam on' switch had been switched DOWN causing the
beam to be always on...  Sticker next to switch indicates this switch stays up was not
seen by User reporting problem.
System check out in progress,
