AUTO W/B BAL switch
Automatic white balance adjustment begins.
During adjustment, the message "AWB: EXECUTING" will be
displayed on the viewfinder screen.
After about one second, the message "AWB: OK" will be
displayed, and the adjustment process will complete.
The adjusted value will be automatically stored in the selected
memory (A or B).
Note
When using a zoom lens with automatic iris control capability,
1)
hunting may occur. Adjust the lens' iris gain control (labeled
IG, IS, S, etc.).
1) Hunting: The automatic iris responds over and over, and the image
repeatedly darkens and lightens.
For more information, refer to the operation manual for the
lens.
About white balance memory
There are two white balance memories: A and B.
When you execute automatic white balance adjustment, the
adjusted white balance value and the settings of the filter
select knobs will be stored in either memory A or B, selected
with the WHITE BAL switch.
The white balance values stored in memory will be preserved
even when power is turned off. When power is turned on
again, the white balance in memory corresponding to the
current WHITE BAL switch setting is retrieved.
By setting FILTER WHT MEM to ON on the <OTHERS 2>
page of the MAINTENANCE menu, you can store a white
balance value for each of the built-in CC filters in memory A
and B individually. In this case, a total of 8 white balance
values can be stored as the camera has four CC filters. The
settings of the filter select knobs are not stored when you
adjust white balance with FILTER WHT MEM set to ON. In this
case, the white balance in memory corresponding to the
current WHITE BAL switch and CC filter select knob settings
is retrieved when power is turned on again.
If automatic black balance or white balance
adjustment fails
If the adjustment process does not end successfully, the error
message "ABB: NG" or "AWB: NG" will be displayed on the
viewfinder screen for approximately three seconds.
If this error message is displayed, try the adjustment again.
If the error message continues to be displayed after several
attempts, the camera requires internal inspection.

Setting the Electronic Shutter

This section explains the different modes which can be used
for the electronic shutter and gives the procedures for setting
the shutter mode and shutter speed.
Note
When a CCU or an external control device, such as an RCP/
RM or MSU, is connected, the electronic shutter is controlled
from the external control device, and the switch on the camera
is disabled.
About the shutter modes
The shutter modes that can be used with the electronic shutter
of the camera and the shutter speeds that may be selected are
as follows:
Shutter mode Shutter speed 1)
Standard 1/100, 1/125, 1/250,
1/500, 1/1000, 1/2000
seconds
ECS (Extended Continuously variable
Clear Scan) in the range of 60.0
Hz to 4300 Hz
1) The values in the table are those with 59.94i. With other formats, the
available values may be different.
Note
With artificial lighting, particularly fluorescent lights and
mercury vapor lamps, the brightness appears to be constant,
but in fact the strength of the red, green, and blue components
varies with the power supply frequency. This phenomenon is
known as "flicker." When using the electronic shutter under
these lighting conditions, there are certain cases in which the
flicker is more noticeable. In particular, color flicker is evident
when the power frequency is 60 Hz. In areas where the power
frequency is 50 Hz, setting the shutter speed to 1/100 second
will reduce the flicker.
Selecting the mode and speed of the shutter
The mode and the shutter speed in Standard mode are set
using the SHUTTER switch.
