to set and position the title characters, (2) to switch the
"LOW LIGHT" indication on or off, (3) to raise or lower the
reference level of the automatic iris adjustment, or (4) to

to "9" or "18", the video output level is raised by 9 dB or
18 dB respectively.
[6] BARS/WB (color bar generation/white balance
adjustment) selector
BARS: When the selector is set to this position, a color
bar signal is generated, supplied to the viewfinder and
output from the VIDEO OUT and the VTR/CCU/CMA
connectors on the CA-325/325P. Use this position for
adjusting the video monitor. At this position, the iris of
the zoom lens attached to the camera will be
automatically closed.

When the AUTO W/B BAL switch [3]is set to WHT or
BLK, the white balance or black balance will be
automatically adjusted (and stored in the memory).
After the adjustment, the memorized white balance
and black balance values are always obtained at this
position.
3200K: At this position the white balance is set to the
factory preset value of an iodine lamp (8200K). When
the selector is set to this position, set the FILTER
selector [1]to an appropriate position. Use this position
when there is no time to adjust the white balance.
When the BARSMWB selector is set to this position, the
automatic white balance adjustment of the AUTO W/B
BAL switch [3]will not operate. (However, the
automatic black balance adjustment of the AUTO W/B
BAL switch [3]operates.)
