External Device
Caution
When using the CCU, the camera tally control is possible for the camera assigned

camera tally cannot be lit.
Notes
• When the video from a camera with the tally lit is being used for program
output, then if you press the FTB button, the tally goes off.
• If you open a file on the hard disk in the source viewer assigned to the video
from a camera with the tally lit, the tally goes off.
When you connect an external device to the FACTORY USE connector on the
