keyword=Note: Fast feedback turns off at low current
Just a note about the fast feedback: when you are running at low beam
currents, the fast feedback turns off (the fast feedback control screen
says "gain fail"), but it comes back on automatically when you ramp back
up to high current. It can turn off if the current is too low, or too
high. If you get this "gain fail" message and it doesn't turn back on on
its own, you need to call MCC and ask them to do a gain search.
