RCPor MSU.
When the DISPLAY switch is set to the DISPLAY
position, a message like the one in the figure below
will be displayed on the viewfinder screen during
adjustment.
After a few seconds the adjustment process will be
complete, and the message “AWB: OK” will be
displayed. The adjusted value is automatically stored
in memory.
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 lens’ operation manual.
When automatic white balance adjustment fails
If the white balance adjustment process does not end
successfully, the error message “AWB: NG” will be
displayed on the viewfinder screen for approximately three
seconds.
If this error message is displayed, try white balance
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 shutter modes and speeds which
can be used for the electronic shutter of this camera.
The SHUTTER switch of this camera does not function.
Use a remote control device, RCP or MSU.
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:
As this product is a super-slow-motion camera of 3-times
speed, the selected shutter speed in effect becomes one-
third, and the ECS frequency becomes 3 times.
1) The values in the table are those with 1080/59.94i. With other formats, the
available values may be different.
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.
The HDCU3300 to be used with this camera has a flicker-
reduction function. If flicker is noticeable, set it to ON.
Selecting the shutter mode and speed
The shutter mode and the shutter speed are set using the
RCP or MSU.
