All IQ2 series digital backs feature a red and a green LED. A flashing green LED indicates that the back is busy exposing the CCD or moving data from the CCD. An illuminated red LED means the back is writing to the storage media. A continuous green light indicates that the display of the IQ back is dimmed, but the back is still ready to shoot.
