Black Balance Adjustment
Correct adjustment of the black balance is important for optimum operation of a video camera. It is necessary when using the camera for the first time or after a significant period out of use, and also when there has been a sudden change in temperature. The adjustment value is saved in memory, and readjustment is not normally necessary after powering the camera off or simply when lighting conditions change.
Notes

Shutter Settings
This section covers the settings for electronic shutter speed, CLS (clear scan ) and EVS function. The new value for the shutter speed or CLS frequency and EVS setting remains set until changed, even when the camera is powered off. Shutter speeds There are five shutter speeds, from 1/100 s (DXC-D30) or 1/60 s (DXC-D30P) to 1/2000 s. Increasing the shutter speed reduces blurring when shooting a fast-moving subject. It is also possible to reduce flicker when shooting under fluorescent lighting by changing the shutter speed. CLS (Clear Scan) function When shooting a computer screen or projected image, horizontal bands may appear in the camera image. This is because the vertical scan frequency of the computer-generated image is different from the vertical scan frequency of the video system. The clear scan function allows you to select a vertical scan frequency to reduce this interference. EVS (Enhanced Vertical Scan) This function enhances the vertical scan resolution from 400 lines to 450 lines to reduce flicker. However, this increases the aliasing.

� When using a camera control unit, if the W/B BALANCE switch of the camera control unit is set to MANUAL, it is not possible to carry out black balance adjustment on the camera. � When using a CCU-M5/M5P Camera Control Unit, make sure that the MODE switch of the CCU-M5/ M5P is in the CAM position. If black balance adjustment cannot be completed automatically The warning message �AUTO BLACK -NG-� appears in the viewfinder. Make the necessary corrections, then carry out the process again.
Warning messages for black balance adjustment Message AUTO BLACK -NG: IRIS NOT CLOSED TRY AGAIN AUTO BLACK -NG: ?? TRY AGAIN BARS Meaning and corrections to be made The lens iris did not close fully. Check whether the lens cable is connected properly, and whether there to a fault in the lens. If a second attempt is carry out the adjustment fails, consult your Sony dealer. The iris opened during adjustment or there is a hardware error. Close the iris and try again. If this fails, consult your Sony dealer. The camera is outputting a color bar signal. Move the OUTPUT/DL/DCC+ switch to one of the CAM positions.

AUTO BLACK -OP-

� The faster you make the shutter speed, the darker the image becomes. Check the brightness in the viewfinder, and if necessary increase the lighting level or adjust the iris. � When the shutter speed is very fast, shooting a high intensity subject may cause long vertical tails to appear on the highlights (smear).
Note on setting the CLS function

Press the UP/ON button or DOWN/OFF button to select the required shutter speed, scan frequency or EVS. Each time you press the UP/ON button or DOWN/ OFF botton, the shutter speed or clear scan frequency setting changes in the following order:
DXC-D30
1/250 1/500 1/1000 1/2000 EVS

1/100 (Value when shipped) 1/60

After a few seconds the adjustment is complete, and the legend in the viewfinder changes to �AUTO BLACK -OK-�.

The vertical scan frequencies of computer screens vary, and it may not be possible to eliminate the interference patterns entirely. Note also that the vertical scan frequency may change depending on the software being run.
