shift in sop
initially were told to do exactly this (if in doubt about severity, use manual mode) but of course am still not a pro in auto mode, especially do not believe a big system should change color from green to yellow within 5 minutes when approaching. have read manuals on internet but main question beside "avoid red" stays:
avoid or accept yellow when not a cell but "all yellow" within a huge area?
initial question about meaning of continuous st elmo's fire still open...
