Adjustment
1. Connect the waveform monitor to D-1 SDI 1 of the
connector panel SD OUT board.
Set the waveform monitor mode to 3H, so that the

straight, it means that the camera moving table
assembly has been pulled out excessively. Return it
back slightly.
2. Rotate the R, G, and B adjustment RVs fully in the
clockwise direction.
