Figure 16. Here, the ring in the upper right corner of the GUI is yellow, indicating that the LDI is in Warm-up mode. The 

operating mode is indicated in the status bar in the lower left corner.

 

Setting the Control Mode 

After  the  unit  completes  Warm-up,  configure  the  desired  shutter  and  intensity  control  modes  from 
'Control  Modes'  tab  in  the  'System  Info  &  Settings'  window.  Th

e  ‘System  Info  &  Settings’  window  is 

accessed by gear icon in the LDI GUI (Figure 17).
