Preparatory Settings
To adjust the white balance
1 Select the built-in filter according to the lighting
conditions with the filter select knob (1: Clear, 2:
1/4 ND, 3: 1/16 ND, 4: 1/64 ND).
2 Place a white pattern, as shown below, with the same
lighting conditions as the subject, and zoom in on it.
A white object (white cloth, a white wall, etc.) near the
subject may be used in place of a white pattern.
Be careful not to have any spots of high illumination in the
rectangle.
3 Adjust the lens iris opening.
With a manually adjusted lens: Set the opening to an
appropriate value.
With a lens which has automatic iris control: Set the
lens’ automatic/manual iris control switch to
automatic.
4 Select white balance memory A or B with the WHITE
BAL switch and push the AUTO W/B BAL switch
toward WHT.
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).
When using a zoom lens with automatic iris control capability,
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 setting of the filter select
knob 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.
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

When a CCU or an external control device, such as an RCP/
RM, is connected, the electronic shutter is controlled from the
external control device or the HKCU-FP1 mounted on the
CCU, 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
