shutter speeds – 1/250, 1/2 000, 1/4 000, and
1/10 000 can be selected.
• In case of using the hybrid control panel, only
OFF, 1/100, or ELC can be selected.
• If the lens iris switch is at M (Manual) when
operating the camera alone or when the iris
switch on the RCU (RCB) is at AUTO, ELC
may not function. Set the lens iris switch to A
(Auto).
• Flickering may increase at ELC under fluorescent
lights.
